MEMORANDUM ***
Jian-Long Liu, a native and citizen of the People’s Republic of China, petitions for review of the Board of Immigration Appeals’ (“BIA”) dismissal of his appeal from an immigration judge’s (“IJ”) denial of his applications for asylum, withholding of removal and relief under the Convention Against Torture (“CAT”). We have jurisdiction pursuant to 8 U.S.C. § 1252. Because the BIA adopted the IJ’s decision *763and also gave reasons of its own, we review both decisions. See Molina-Estrada v. INS, 293 F.3d 1089, 1093 (9th Cir.2002). We review for substantial evidence, Gui v. INS, 280 F.3d 1217, 1225 (9th Cir.2002), and deny the petition for review.
Substantial evidence supports the agency’s adverse credibility determination because Liu testified that his wife was forcibly taken by the government authorities to be sterilized, but Liu failed to mention the alleged tubal ligation in either of his asylum applications or in the accompanying addenda. Liu explained that he did not discuss the tubal ligation in his application materials because “[ejverybody know[s] that the Chinese government has this family planning policy.” The agency was “not unreasonable in considering that, if truthful, [Liu] would have thought to mention his most serious allegation of mistreatment when he detailed the persecution he and his family allegedly endured.” Li v. Ashcroft, 378 F.3d 959, 963 (9th Cir.2004). Without credible testimony, the record lacks evidence to support a determination that Liu suffered past persecution or that he has a well-founded fear of future persecution. See Mejia-Paiz v. INS, 111 F.3d 720, 724 (9th Cir.1997).
Because Liu failed to prove eligibility for asylum, he necessarily failed to meet the more stringent standard for withholding of removal. See Alvarez-Santos v. INS, 332 F.3d 1245, 1255 (9th Cir.2003).
Liu, represented by counsel, made no argument in his opening brief regarding his claim for relief under CAT. Therefore, he has waived his right to challenge the IJ’s denial of CAT relief. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259 (9th Cir.1996) (issues raised in a brief which are not supported by argument are deemed abandoned).
PETITION FOR REVIEW DENIED.
