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”.
He is the latest in a series of high-profile executives to become embroiled in Beijing’s crackdown on corruption.
The government’s ongoing anti-corruption drive resulted in more than 70 senior officials at state firms being investigated in 2014.
