HONG KONG (AP) — The biggest Chinese airline says its chairman is being investigated by the country's anti-corruption agency.
China Southern Airlines said Thursday that Si Xianmin is being investigated "by the relevant authorities for suspected serious disciplinary violations." The phrase usually refers to corruption.
No details were given in the brief statement to Hong Kong's stock exchange. The statement followed a similar announcement posted late Wednesday on the website of the Central Commission for Discipline Inspection, China's top anti-graft body.
Si is the latest top executive at a state owned company caught up in President Xi Jinping's widening anti-corruption crackdown.
Earlier this week, the commission said it was investigating automaker Dongfeng Motor's general manager.
China Southern is the country's biggest airline by passengers and fleet size.
