BEIJING - PetroChina, China's largest oil and gas producer, reported expansion in revenue in 2019, while its net profit saw a remarkable drop due to the slowing global economic growth and unrest in the international oil market.

Revenue rose 6 percent year-on-year to 2.52 trillion yuan ($355.22 billion), according to the company's annual financial report. The sector of exploration and production, the brightest spot, generated a 30.7-percent increase in profit.

Net profits attributable to equity holders came in at 45.68 billion yuan, slipping by 13.9 percent from the previous year, the report showed.

PetroChina said the performance met profit forecasts, with major production indicators growing steadily despite the complex and grim situation of the global oil market affected by the gloomy economic outlook and sharp decline in oil prices.

Facing challenges arising from intensifying downward economic pressure and the further shrink in oil prices, the company vowed to uphold innovation strategies and promote high-quality development.
