China imposed Saturday limits on petroleum product exports to North Korea and banned imports of textiles from the country in line with the latest U.N. sanctions over its nuclear program.

The Commerce Ministry said exports of refined petroleum products to North Korea will be limited to 500,000 barrels from Oct. 1 to Dec. 31 and to 2 million barrels per year starting Jan. 1.

The ceilings are stipulated in a resolution approved by the U.N. Security Council this month in response to North Korea's sixth and most powerful nuclear test on Sept. 3.

The U.N. resolution imposes additional sanctions on North Korea, which has been making rapid progress in its quest to develop a nuclear-tipped intercontinental ballistic missile.

The resolution also bans exports to North Korea of natural gas liquids and light crude condensate, a natural gas by-product.

As for textiles, one of North Korea's biggest sources of foreign revenue, the ministry said they cannot be imported starting Saturday midnight.

China accounts for about 90 percent of North Korea's total trade and supplies a huge amount of food and energy.

China, which has been under strong pressure from the United States to do more to rein in North Korea's weapons program, has pledged to fully implement the U.N. sanctions.

The Chinese ministry made the announcement Friday night and it took effect Saturday.
