The chairman of one of China’s largest state-owned mobile operators, China Telecom, is being investigated by the country’s anti-corruption watchdog.

Chang Xiaobing is “suspected of serious violation of discipline”, according to a statement on the Central Commission for Discipline Inspection website. The executive was reported missing by local media on Sunday.

He is the latest in a series of high-profile executives to become embroiled in Beijing’s crackdown on corruption.

Correspondents say that Beijing’s crackdown on corruption is partly about using high profile cases to prove the government is serious about tackling corruption.
