No involvement. Xuan Changwei used to be the former Party Secretary and Deputy General Manager of Kunlun Project of China Petroleum and Natural Gas Corporation, and was later prosecuted for corruption and bribery. Xuan Changwei's case has nothing to do with Fushun Petrochemical, and he has never worked in Fushun Petrochemical, so he will not be implicated in Fushun Petrochemical.
