A senior official of China National Offshore Oil Company (CNOOC) was detained within an investigation for bribery, according to the website of the Supreme People’s Procuratorate.

As General Manager of CNOOC Gas & Power group, a wholly-owned subsidiary of CNOOC, Luo Weizhong was running investment deals in multi-billion dollar gas import terminals and deciding upon long term liquefied natural gas import deals.

The detaining comes as the Chinese president Xi Jinping tightens his war on corruption, launched since he took office.

The anti-corruption campaign has spread to various executive branches across Chinese businesses and governmental bodies, including the military, with the top retired general Xu Caihou confessing to taking bribes recently.
