PetroChina overseas operations chief Bo Qiliang under investigation - company source
BEIJING May 16 (Reuters) - PetroChina's overseas operations chief Bo Qiliang is under official investigation after being removed from his post, a company source with knowledge of the matter told Reuters.
Earlier on Friday, PetroChina said in a filing with the Shanghai Stock Exchange that Bo had left his post due to a change in job role, but did not give a reason.
Bo will be replaced by Lu Gongxun, the former head of PetroChina in Kazakhstan.
PetroChina spokesman Mao Zefeng reiterated the stock exchange statement but declined further comment when asked by Reuters.
