Investing.com -- China's refined oil product exports fell 38% in April compared to the same month last year, reaching 3.12 million metric tons, according to customs data released on Monday by the General Administration of Customs.

The decline follows fuel export restrictions implemented in mid-March to limit the impact of the Iran war on domestic supply. Beijing designated export volumes for specific countries including Vietnam, Indonesia, Malaysia, Australia and the Philippines.

The restrictions exempt exports to Hong Kong and Macau, as well as aviation fuel for international flights and bunker sales for international shipping voyages.

Jet fuel exports declined 47.5% to 990,000 tons in April, while diesel exports fell 54.8% to 230,000 tons.

For the first four months of 2026, China exported 15.87 million tons of refined oil products, down 9% from the same period in 2025.

The customs data also showed LNG imports dropped to 3.55 million tons in April, the lowest level in eight years, representing a 23% decrease from April 2025.

China imported 17.94 million tons of LNG in the first four months of 2026, down 10.3% compared to the same period last year.
