A senior official from China's top anti-graft watchdog vowed on Friday to enhance international cooperation to catch corrupt officials who have fled overseas.

Huang Shuxian, vice-secretary of the Central Commission for Discipline Inspection of the Communist Party of China, also said that Chinese anti-graft authorities will tighten regulations on officials' passports, keep a close eye on international capital flow and strictly follow regulations overseeing officials' spouses and children who have emigrated. These steps, Huang said, will prevent officials from fleeing overseas.

"Even though corrupt officials have fled to the end of the earth, we will bring them back to face the law," he said.
