“It sends the unambiguous message to Pyongyang that further defiance will invite further punishment and isolation,” U.S. Ambassador Nikki Haley said of the new resolution after the vote Friday.

The resolution adopted by all 15 council members Thursday doesn’t go as far as the toughest-ever sanctions that have been sought by the Trump administration, such as prohibiting all oil imports and freezing international assets of North Korea’s government and its leader, Kim Jong Un.

The resolution caps North Korea’s crude oil imports at 4 million barrels a year and limits its imports of refined oil products, including diesel and kerosene, to 500,000 barrels a year. That would be a nearly 90 percent cut in imported fuels that are key to North Korea’s economy.
