Wang Guoqiang, former Communist Party of China (CPC) chief of Fengcheng city in northeast China's Liaoning province, Monday returned to China from the US and turned himself in to the discipline authority.
This is one of the key cases currently being handled by a high ranking anti-corruption office in its quest to repatriate suspects and return stolen assets to the state in the country's wider anti-corruption drive, Xinhua reported.
Both China and the US acknowledged that this was an important case, according to the CPC Central Commission for Discipline Inspection.
Wang fled in 2012 and returned following the joint efforts of various central departments and local authorities. The US also provided support to the Chinese authorities, according to the commission.
Wang gave himself up along with a confession statement.
The investigation will continue.
