Defendant Robsac Industries (“Robsac”) appeals the district court’s entry of summary judgment for Continental Casualty Company (“Continental”) on Continental’s action for declaratory relief and its summary denial of Robsac’s motion to stay the declaratory relief action pending the outcome of a parallel state court proceeding on the merits. This case raises the oft recurring problem of the proper role of the federal courts in the resolution of disputes relating to obligations under insurance policies, an area primarily within the jurisdiction of the state courts. We hold that in light of the pending state action the district court should not have exercised its jurisdiction to grant declaratory relief. Accordingly, we reverse and remand to the district court with instructions to dismiss the action.
FACTS AND PROCEEDINGS BELOW
Robsac is a California corporation. Prior to January, 1987, when it filed a bankruptcy petition, Robsac was in the business of selling artist and drafting supplies through its stores in several cities throughout the United States. In December, 1984, Continental, an Illinois corporation, issued an insurance policy to Robsac along with five other named subsidiaries. In September, 1986, Robert Sachs, the president of Rob-sac, contacted Robsac’s insurance agent and advised him of a potential theft loss. As instructed by the agent, Robsac hired a private investigator to investigate the theft-loss claim. Robsac submitted an official “Proof of Loss” form to Continental on June 17, 1987. On November 25, 1987, Continental denied the claim in a letter to Robsac. Robsac filed suit against Continental for breach of contract in Los Ange-les Superior Court on December 2, 1987. In addition to Continental, Robsac also named as defendants 50 Continental mana*1369gerial level employees, designated as “Does 1 through 50.” The parties agree that some of those employees work and reside in California. Almost a month later, on December 28, 1987, Continental filed this declaratory judgment action in the United States District Court for the Eastern District of Illinois. Continental sought a declaratory judgment that it was not liable under the policy. The sole basis for federal subject matter jurisdiction was diversity of citizenship, 28 U.S.C. § 1332. On June 1, 1988, Robsac moved for a stay of the federal action, or in the alternative, a transfer to the Central District of California. The alternative motion was granted and the case transferred.
On March 7, 1989, Robsac again moved to stay the federal action based upon the pendency of the state action, this time making its motion before the United States District Court for the Central District of California. The parties agree that the district court summarily denied the motion on April 3, 1989, although nothing in the record indicates that an order was ever entered reflecting this decision. Continental then moved for summary judgment on June 6, 1988. Continental argued that Robsac had assigned its entire interest in the claim to a third party or had waived any remaining interest, and that in any event Robsac had not introduced any admissible evidence to prove its alleged theft loss.
On April 28, 1989 the district court heard the motion and entered judgment in favor of Continental and against Robsac on the basis of the assignment/waiver issue. The court did not reach the underlying question whether Continental was liable (to Robsac or an assignee) under the policy. Robsac made an untimely motion for new trial or in the alternative, for reconsideration, which the court denied.1
Robsac filed a timely appeal of the grant of Continental’s summary judgment motion. We have jurisdiction under 28 U.S.C. § 1291.
DISCUSSION
Robsac argues that the district court abused its discretion by granting declaratory relief during the pendency of the state court proceedings. Robsac relies principally on Colorado River Water Conservation District v. United States, 424 U.S. 800, 96 S.Ct. 1236, 47 L.Ed.2d 483 (1976), and Moses H. Cone Memorial Hospital v. Mercury Construction Corp., 460 U.S. 1, 103 S.Ct. 927, 74 L.Ed.2d 765 (1983), which set forth a total of six factors to which district courts generally should look in deciding whether to stay federal proceedings in favor of pending state court proceedings concerning the same subject matter. However, we recently held that “[t]he Colorado River test ... does not apply where the Declaratory Judgments Act, 28 U.S.C. § 2201, is involved.” Chamberlain v. Allstate Ins. Co., 931 F.2d 1361, 1366 (9th Cir.1991). Accordingly, the district court did not err in failing to abstain under the Colorado River doctrine.
Nonetheless, in light of Robsac’s stay request, abstention is required under a different but related doctrine — the one applicable to declaratory relief cases. This doctrine was first set forth in Brillhart v. Excess Ins. Co., 316 U.S. 491, 62 S.Ct. 1173, 86 L.Ed. 1620 (1942). It stems from the fact that by its express terms the Declaratory Judgments Act makes the granting of declaratory relief discretionary. 28 U.S.C. § 2201(a) (“any court of the United States, upon the filing of an appropriate pleading, may declare the rights and other legal relations of any interested party seeking such declaration”) (emphasis added). At the time that Robsac moved for a stay our cases could have been read to imply that abstention under Colorado River and abstention pursuant to the terms of the Declaratory Judgments Act are governed by the same standards. Compare Transamerica Occidental Life Ins. Co. v. Digregorio, 811 F.2d 1249, 1254 (9th Cir.1987) with Mobil Oil Corp. v. City of Long *1370Beach, 772 F.2d 534, 542 (9th Cir.1985). We have recently made clear, however, that this is not the case. See Chamberlain, 931 F.2d at 1366 n. 1. In Chamberlain, we narrowed considerably the discretion courts have to issue declaratory relief. We held that quite apart from any considerations under Colorado River, a district court’s discretion to grant relief under the Declaratory Judgments Act ordinarily should not be exercised “where another suit is pending in a state court presenting the same issues, not governed by federal law, between the same parties.” Id. at 1366 (quoting Brillhart, 316 U.S. at 495, 62 S.Ct. at 1176).2
The record does not indicate why the district court decided to exercise its jurisdiction. However, this does not prevent us from considering the issue, because “[w]e review de novo the district court’s decision to exercise its jurisdiction under the Declaratory Judgments Act when a state action is pending.” Chamberlain, 931 F.2d at 1366 (citing Fireman’s Fund Ins. Co. v. Ignacio, 860 F.2d 353, 354 (9th Cir.1988) (per curiam)). We may conduct that review now or remand and delay doing so until after another appeal is taken. See Allstate Ins. Co. v. Mercier, 913 F.2d 273, 277 (6th Cir.1990). Whether we retain jurisdiction and proceed to decide the issue before us or whether we remand to the district court and defer our decision until later, we will still ultimately be obligated to exercise our own discretion in considering the propriety of the district court’s grant or denial of declaratory relief.3 Given the importance of the issue raised in this case and the delay already incurred by the parties, we elect to review the district court’s exercise of jurisdiction now.
In considering the issue ourselves, we are guided by the same criteria and factors as guide the district court in its exercise of jurisdiction. See note 3 supra. We thus put ourselves in the same position as a district judge and determine whether, in the exercise of our discretion, the assumption of jurisdiction over this declaratory judgment action was proper. See United States v. State of Washington, 759 F.2d 1353, 1356-57 (9th Cir.1985) (en banc) (per curiam) (“The court of appeals must exercise its own sound discretion to determine the propriety of the district court’s grant or denial of declaratory relief.”).
In resolving this appeal, we must apply the legal principles applicable at the time we consider the issue. See id. at 1357 (setting forth principles with respect to previously unsettled question governing the standards for exercising discretion to grant declaratory relief, and reversing the district court’s grant of such relief on that basis). Accordingly, having elected to decide the question before us, we must now determine whether, under Chamberlain, Continental’s declaratory relief action should be dismissed in deference to the pending state court proceeding. If it should be, then we are obligated to reverse, even if the law did not clearly establish that abstention was required at the time that the district court considered the question.
As we stated in Chamberlain, when a state court action is pending presenting the same issue of state law as is presented in a federal declaratory suit, “there exists a presumption that the entire suit should be *1371heard in state court.” Chamberlain, 931 F.2d at 1366-67 (citing Brillhart, 316 U.S. at 495, 62 S.Ct. at 1176). We also noted in Chamberlain that the Supreme Court’s decision in Brillhart was based on three principal rationales. “First, the Court wanted to avoid having federal courts needlessly determine issues of state law.” Chamberlain, 931 F.2d at 1367. Second, the Court wished to discourage litigants from filing declaratory judgment actions as a means of forum shopping. Id. Third, the Court relied upon a policy of avoiding duplicative litigation. Id. We consider these factors in turn.
First, it is clear that the federal court could have avoided a needless determination of state law by not exercising its jurisdiction. The precise state law issues at stake in the present case are the subject of a parallel proceeding in state court. In the federal case, a diversity action, California law provides the rule of decision for all of the substantive questions. Moreover, this case involves insurance law, an area that Congress has expressly left to the states through the McCarran-Ferguson Act. 15 U.S.C. §§ 1011-12 (1988). Although this case does not involve Burford abstention, see Burford v. Sun Oil Co., 319 U.S. 315, 63 S.Ct. 1098, 87 L.Ed. 1424 (1943), it is worth noting that the Burford abstention doctrine’s concern “with protecting complex state administrative processes from undue federal interference,” New Orleans Public Serv. v. Council of New Orleans, 491 U.S. 350, 361, 109 S.Ct. 2506, 2514, 105 L.Ed.2d 298 (1989), is also implicated here, where California has established a complex scheme of insurance regulation.
Indeed, we upheld a stay in another declaratory judgment case principally on the basis that there was no compelling federal interest. See Digregorio, 811 F.2d at 1255. Yet in that case there was federal question jurisdiction under the Employee Retirement Income Security Act (ERISA), 29 U.S.C. §§ 1001-1461, suggesting a Congressional recognition of some federal interest in the case. Where, as in the case before us, the sole basis of jurisdiction is diversity of citizenship, the federal interest is at its nadir. Thus, the Brillhart policy of avoiding unnecessary declarations of state law is especially strong here.
We next turn to the second Brillhart factor — the interest in avoiding the use by litigants of declaratory judgment actions as a means of forum shopping. See Chamberlain, 931 F.2d at 1367. We have also described this factor as relating to “the ‘defensive’ or ‘reactive’ nature of a federal declaratory judgment suit,” and stated that if a declaratory judgment suit is defensive or reactive, that would justify a court’s decision not to exercise jurisdiction. Digre-gorio, 811 F.2d at 1254 n. 4.
The present suit was filed in federal court because the insurer apparently perceived a tactical advantage from litigating in a federal forum. Disputes in which insurance companies have sought declaratory relief in federal court have arisen frequently in the past. Often an insurer has brought a declaratory judgment action in federal court against its insured in order to obtain a ruling as to its obligations in relation to a state court action by a third party against the insured. Although the insurer would have been unable to remove the state court action to federal court in most cases due to lack of complete diversity under 28 U.S.C. § 1441(b), there was diversity jurisdiction in the suit for declaratory relief because the insurer and insured were citizens of different states.4 However, we have stated that the ripeness requirement of Article Ill’s “case or controversy” clause precludes the insurer’s obtaining a declaratory judgment with respect to its liability to the insured in such cases be*1372cause “the federal relief sought may hinge upon the outcome of state court actions.” Ticor Title Ins. Co. of Cal. v. American Resources, Ltd., 859 F.2d 772, 777 n. 7 (9th Cir.1988). In light of Chamberlain, the result may well be the same with respect to a determination as to the insurer’s duty to defend. Although the Sixth Circuit has recently held that district courts should dismiss such cases, see Allstate Ins. Co. v. Mercier, 913 F.2d 273 (6th Cir.1990), we have not yet addressed the question, see Ticor Title Ins. Co., 859 F.2d at 773-74.
While the present case does not involve an underlying state court action by a third party, it raises closely related concerns. Here, the insured Robsac (a California citizen) sued its insurer Continental (an Illinois citizen) in state court, and as part of the same action also sued other defendants (some of whom are citizens of California). The case could not have been removed to federal court because there was not complete diversity. See 28 U.S.C. § 1441(b) and (c).5 As a result, in an effort to obtain a federal forum, the insurance carrier brought an action seeking a declaration that it was not liable for any coverage under the policy.
A declaratory judgment action by an insurance company against its insured during the pendency of a non-removable state court action presenting the same issues of state law is an archetype of what we have termed “reactive” litigation. Digregorio, 811 F.2d at 1254 n. 4. Continental argues, however, that because it intended to file its federal suit for declaratory relief even before Robsac filed its complaint in state court, the federal action is not truly “reactive.” We are not persuaded that Continental accurately characterizes the sequence of events, but even if we were, that would not affect our conclusion that the present suit is “reactive.” Reactive litigation can occur in response to a claim an insurance carrier believes to be not subject to coverage even though the claimant has not yet filed his state court action: the insurer may anticipate that its insured intends to file a non-removable state court action, and rush to file a federal action before the insured does so. If, as Continental contends, it intended to file suit in federal court before Robsac filed its state court action, the reason it formed that intention was that it was aware of Robsac’s claim and hoped to preempt any state court proceeding. Whether the federal declaratory judgment action regarding *1373insurance coverage is filed first or second, it is reactive, and permitting it to go forward when there is a pending state court case presenting the identical issue would encourage forum shopping in violation of the second Brillhart principle.
The third Brillhart factor is the policy of avoidance of duplicative litigation. Here it is clear that that policy would be frustrated by permitting the federal action to go forward during the pendency of the state court action because the federal declaratory suit is virtually the mirror image of the state suit. All of the issues presented by the declaratory judgment action could be resolved by the state court.6 Hence, permitting the present action to go forward would waste judicial resources in violation of the third Brillhart factor.
In addition to the three principal Brillhart factors discussed in Chamberlain, there are at least two others that require a decision not to exercise jurisdiction in the present ease. First, there is the general policy of avoiding piecemeal litigation. See Chamberlain, 931 F.2d at 1368. Piecemeal litigation would result if the federal court were to determine Robsac’s rights against Continental, but not against the individual defendants.
Second, allowing this action to proceed would violate the spirit, if not the letter, of the diversity removal provision. Congress decided to permit removal of a state court action to federal court on the basis of diversity of citizenship only where there is complete diversity. See 28 U.S.C. § 1441(b) and (c). Congress could have authorized partial removal of such cases, but apparently determined that the costs due to du-plicative and piecemeal litigation that would have resulted outweighed any benefits of such a scheme.7 To permit the present declaratory judgment action to proceed while there are non-diverse defendants in the state suit who are not parties to the federal action would be to sanction partial removal in all but name. We give considerable weight to the Congressional policy of 28 U.S.C. § 1441(b), and we cannot approve Continental’s attempt to circumvent that policy.8
We conclude that there are particularly strong reasons to apply the Brillhart “presumption that the entire suit should be heard in state court.” Chamberlain, 931 F.2d at 1367. We now consider whether there are any factors favoring the exercise of federal jurisdiction that might rebut the presumption.
Chamberlain was a case in which we held that declaratory relief was appropriate notwithstanding the fact that there was a pending state court declaratory action involving the identical question. The reason we so held was that in Chamberlain the declaratory judgment action in the federal court was a counterclaim to a claim seeking monetary relief. Because the district court’s jurisdiction over the claim for monetary relief was not discretionary, there was no way for the federal court to dismiss the entire action. If the district court dismissed the declaratory judgment counterclaim the result would have been piecemeal *1374litigation: the federal court would have been left with the claim for monetary relief and the state court would have had to decide the declaratory relief claim. We held that the federal court’s granting of declaratory relief was appropriate under those circumstances because only the federal court could resolve the entire coverage dispute. 931 F.2d at 1366-68. By contrast, in the present case, only the state court can adjudicate the entire dispute because of the non-diverse defendants. Cf Allstate, 913 F.2d at 278-79 (state court “would be in a superior position to address the legal issues on which [the insurer] seeks a declaration of rights”). Hence, the circumstance which justified departure from the Brillhart presumption in Chamberlain is not present here. Nor are there any other circumstances that would warrant such a departure.9 Thus, to paraphrase the court in United States v. State of Washington, we choose to rest our decision in this case on the proposition that issuance of the declaratory judgment with respect to the insurance coverage dispute is contrary to the exercise of sound judicial discretion. See 759 F.2d at 1357.
CONCLUSION
We hold that the district court’s exercise of jurisdiction in this case was contrary to the exercise of sound judicial discretion. Courts should generally decline to assert jurisdiction in insurance coverage and other declaratory relief actions presenting only issues of state law during the pendency of parallel proceedings in state court. There are no circumstances present in this case that warrant an exception to that rule.
Accordingly, the judgment of the court below is reversed. The district court is instructed to dismiss the case.
REVERSED AND REMANDED WITH INSTRUCTIONS TO DISMISS.
. The denial of the untimely motion for reconsideration is not at issue on this appeal. We agree with the district court that there was no basis for Robsac’s motion for new trial, as there was no trial in the court below.
. Given our statement in Mobil Oil that the statutory discretion to grant declaratory relief "must be exercised within the narrow boundaries drawn by Colorado River " when "denial of relief is based on principles of 'wise judicial administration,’ ” 772 F.2d at 542 (quoting Moses H. Cone, 460 U.S. at 19, 103 S.Ct. at 939), we cannot fault Robsac for failing to rely on Brilt-hart as a separate basis for abstention. Although we stated in Digregorio that Mobil Oil "must be applied circumspectly," 811 F.2d at 1254, it was not until our decision in Chamberlain that we expressly decided that the Colorado River principles are entirely inapplicable to suits brought under the Declaratory Judgments Act.
. As the Sixth Circuit stated in Allstate:
These same criteria and factors provide the basis for a district court’s exercise of its discretion. When the record contains no indication that the district court considered these criteria and factors, this court has the option either to apply them on appeal or to remand to the district court for this exercise.
Id. at 277 (citations omitted).
. There will generally be diversity jurisdiction in a suit by an insurer against its insured because most major insurance companies do business nationally, but for purposes of the diversity statute, are “citizens” of only two states — the state of incorporation and the state in which the company has its "principal place of business." 28 U.S.C. § 1332(c)(1). Thus, there will be diversity jurisdiction in a suit between a typical insurance company and its insureds who are domiciled in any of 48 states. However, diversity jurisdiction will usually be defeated if the third party who brought suit against the insured is part of the action because the kinds of occurrences that give rise to liability suits generally involve citizens of the same state.
. In the present case, the lack of diversity is a result of the existence of Doe defendants. In other cases it will result from the presence of two or more named defendants, at least one of whom is a citizen of the same state as the plaintiff. At the time the present suit was brought, 28 U.S.C. § 1441(c) provided:
Whenever a separate and independent claim or cause of action, which would be removable if sued upon alone, is joined with one or more otherwise non-removable claims or causes of action, the entire case may be removed and the district court may determine all issues therein, or, in its discretion, may remand all matters not otherwise within its original jurisdiction.
Congress recently amended section 1441(c) by replacing "would be removable if sued upon alone” with "within the jurisdiction conferred by section 1331 of this title” and by replacing "remand all matters not otherwise within its original jurisdiction" with “may remand all matters in which State law predominates.” See Judicial Improvements Act of 1990, Pub.L. No. 101-650, § 312, 104 Stat. 5089, 5114.
Continental concedes that under the old version of section 1441(c) the case could not have been removed, and does not contend that Rob-sac’s state suit against Continental was removable as an "independent claim or cause of action.” The amendment to 1441(c) does not appear to have any effect on the removability of the action.
It is also worth noting that at the time Continental brought its declaratory judgment action, our rule was that the presence of Doe defendants in the state court action precludes removal. See Bryant v. Ford Motor Co., 844 F.2d 602, 605 (9th Cir.1987) (en banc). Subsequently, Congress amended 28 U.S.C. § 1332, so that the presence of defendants sued under fictitious names no longer defeats diversity jurisdiction. See Judicial Improvements and Access to Justice Act, Pub.L. No. 100-702, 102 Stat. 4642 (1988). We are unaware whether Robsac has learned the true names of the Doe defendants, although Continental has conceded that some of them are California residents. In any event, we proceed on the assumption — shared by both parties— that this case could not have been removed at the time Continental filed its declaratory judgment action or the time the district court denied the motion to stay and granted declaratory relief.
. Indeed, the state court can also resolve the additional claims involving the non-diverse defendants.
. The recent amendments to Title 28 of the United States Code, discussed supra n. 4, do not undermine the conclusion that Congress has chosen not to allow partial removal of diversity cases, at least where all the defendants are known. Indeed, as the House Report on the most recent amendment to 28 U.S.C. § 1441 states, a rule prohibiting partial removal in diversity cases is justified because “the need to provide removal for diverse defendants is not great." H.R.Rep. No. 101-734, 101st Cong., 2d Sess. 23, reprinted in 1990 U.S.Code Cong. & Admin.News 6802, 6860, 6869.
.The potential for avoidance of the policy against partial removal is by no means confined to insurance cases. A grant of declaratory relief in this case would set a precedent for the garden variety case in which A (a citizen of state 1) sues joint tortfeasors B (a citizen of state 1) and C (a citizen of state 2) on the basis of the law of state 1 in a court of state 1. Such a case is indisputably unremovable under 28 Ú.S.C. § 1441(b) and (c), in whole or in part. Yet under the theory advanced by Continental, C could bring a declaratory judgment action in federal court, seeking a declaration that it is not liable to A. Thus, the declaratory judgment action would be converted into a vehicle for defeating the Congressional policy against partial removal of diversity cases.
. It might be argued that where a district court improperly exercised jurisdiction to grant a declaratory judgment, but nonetheless reached a correct decision on the merits, it would, at least in some circumstances, be a waste of judicial resources for the court of appeals to vacate the judgment in order for a state court to duplicate the district court's efforts. Whatever the merits of such an argument, it would in any event fail here. In the first place, the case before us was decided on summary judgment and the expenditure of judicial resources was thus comparatively minimal. In the second, for reasons that do not warrant extensive discussion here, the district court’s decision granting summary judgment was in error. There is a genuine issue of material fact with respect to the question whether Robsac assigned or waived all of its rights to the claim at issue here. While Continental also urges us to affirm the district court's summary judgment decision on the basis of a ground not considered below, in view of the fact that the district court should not have addressed the merits of this case at all, we decline to do so.
