PetroChina is a Beijing-based oil and gas company. The company is a subsidiary of China National Petroleum Corporation (CNPC).

Higher global energy prices helped Asia’s largest oil and gas producer, PetroChina Co Ltd, post a 60% year-over-year increase in nine-month net profit despite the lower domestic fuel demand hurting earnings. PetroChina’s net profit from January to September 2022 was 120.3 billion yuan ($16.66 billion). The company intends to increase its natural gas production to account for 55% of total output by 2025.
