Where does PetroChina pay social security?

The social security management institution where the local branch or subsidiary of China Petroleum is located. According to the inquiry of official website of China Petroleum and Natural Gas Group Company, China's social endowment insurance is a localized management mode, that is, where the company is registered, employees' social security needs to be paid. As a large-scale central enterprise, PetroChina is headquartered in Beijing, but its subordinate second-,third-and fourth-level companies are distributed all over the country. Therefore, the social security of PetroChina employees needs to be handed over to the social security management agency where its branch or subsidiary is located.
