Li Huabo, a former financial official in the central province of Jiangxi who is suspected of embezzling 94 million yuan (USD 15.4 million), fled China in 2011, the official Xinhua news agency said.
The Communist Party's corruption watchdog showed a photo on its website of Li being marched down the stairs of an airplane with a police officer holding each arm.
Li was sentenced to 15 months in prison by a Singapore court on another charge, served the jail term and then was repatriated after his release, Xinhua said. It did not say when or if he would face trial in China.
Li is shown second on a list of 100 wanted people issued in April as part of the campaign, with a photo of him sporting a moustache and a red polo shirt.
