China’s oil giant, PetroChina Company Limited (NYSE:PTR), received notice of an investigation from a U.S. court on after being alerted to suspicion that former and current heads of the company may have violated U.S. security regulations, Reuters reported Tuesday.

An overseas shareholder filed the complaint with the U.S. District Court for the Southern District of New York against ex-Chairman Jiang Jiemin, current Chairman Zhou Jiping, former Chief Financial Officer Zhou Mingchun and current CFO Yu Yibo.
