China secured stable domestic oil and gas supply in the first quarter, effectively dampening external shocks from global geopolitical tensions, including conflicts involving the Middle East, according to authorities.

Output of crude oil and natural gas from major industrial enterprises rose 1.3 percent and 3.0 percent year-on-year, respectively, during the first quarter, Xing Yiteng, deputy director of the National Energy Administration's Department of Development Planning, said during a press conference held in Beijing on Monday.

Coal production remained steady against a high comparison base last year, with a mild 0.1 percent year-on-year growth in output of major industrial coal producers, he said.

According to Xing, energy investment maintained robust growth in the quarter, giving strong impetus to the rebound of national fixed-asset investment.

Power grid expansion and safety upgrades gathered pace, alongside accelerated investment in hydrogen energy, coal-to-fuel projects, and new energy storage. Private enterprises have also deepened participation in key national energy research initiatives as well, he said.
