Difference between China Oil and Gas Co., Ltd. and Group Company

The Group is the major shareholder of the joint-stock company, and the high-quality assets spun off from the group company are listed in Hongkong and new york for margin financing and securities lending. PetroChina mainly includes oil and gas exploration and development, natural gas and pipelines, refining and chemical industry, oil and gas sales, PetroChina engineering, foreign cooperation, and planning and design of petroleum and petrochemical industry. Other companies that have not been selected as joint-stock companies are mainly companies that have been restructured after divestiture of high-quality assets, companies that are indispensable for overall production, and companies that are too big to be divested and listed, but this does not mean that assets that will not be improved will not be invested. These other companies mainly include finance, trust, insurance, enterprise annuity management, hospitals, transportation, education and training, media and equipment manufacturing.
