The former head of one China North Industries Group Corporation (Norinco) - one of the largest weapons manufacturers in the country, Yin Jiaxu is under investigation for alleged corruption offences, according to the Communist Party's anti-corruption watchdog.
Yin Jiaxu was Communist Party chief and chairman ountil his retirement in 2018, reports the South China Moring Post.
He is being investigated for "serious violations of discipline and the law", the Central Commission for Discipline Inspection (CCDI) said on Sunday, without elaborating on his alleged wrongdoings.
The 65-year old Yin is the latest high-level official from the defence industry to be snared by President Xi Jinping's sweeping anti-corruption campaign that has seen more than 1.3 million officials investigated since 2012.
In January, the CCDI announced that Hu Wenming, the former party chief and chairman of China Shipbuilding Industry Corporation, who oversaw the development of the Liaoning and Shandong aircraft carriers, had been expelled from the party for taking bribes and abusing his power.
Yin replaced Hu as deputy general manager of Norinco in 2010 and took over as party chief in 2014. It is not known if the two cases are connected.
Norinco supplies weapons and equipment to all branches of the Chinese military and armed police force.
According to a December report by Stockholm International Peace Research Institute, it is the ninth-largest arms company in the world and third-largest in China, after Aviation Industry Corporation of China and China Electronics Technology Group Corporation.
