UNITED NATIONS — The U.N. Security Council on Saturday unanimously adopted a resolution to impose the most punishing sanctions yet against North Korea over its repeated defiance of a ban on testing missiles and nuclear bombs.

The resolution, intended to press North Korea to renounce its nuclear militarization, could reduce the isolated country’s already meager annual export revenue by $1 billion, or about a third of its current total.

Ambassador Nikki R. Haley of the United States, which introduced the resolution, said its adoption by all 15 council members signified what she called “a strong, united step toward holding North Korea accountable for its behavior.”


Haley described the new penalties, which the U.S. painstakingly negotiated with China, North Korea’s most important trading partner, as “the most stringent set of sanctions on any country in a generation.” She also said they would give North Korea’s leaders “a taste of the deprivation they have chosen to inflict on the North Korean people.”

Before she walked into the Security Council chambers for the vote, Haley stopped and told reporters, “All this ICBM and nuclear irresponsibility has to stop.”

The measure’s unanimous approval was a diplomatic victory for the Trump administration and partly reflected growing impatience with North Korea by China, which historically has called relations between them as “close as lips and teeth.”

President Donald Trump has repeatedly cajoled China to exert more pressure on North Korea over its nuclear belligerence.

Whether Trump’s badgering played any role in China’s support for the resolution is unclear. But its willingness to enforce the resolution’s provisions will be critical to its effectiveness.

China’s ambassador to the United Nations, Liu Jieyi, hinted at his country’s vexation with North Korea in his Security Council remarks after the vote. He urged North Korean authorities to “cease taking actions that might further escalate tensions.”


But Liu also criticized the U.S., calling for dismantlement of a missile defense system it has begun installing in South Korea, which China also regards as counterproductive.

Since 2006, North Korea has defied a half-dozen Security Council resolutions over its nuclear and missile development, which North Korea’s leader, Kim Jong Un, has called a necessary, just response to military threats by the U.S. and South Korea.

The latest resolution was a direct reaction to two North Korean tests last month of intercontinental ballistic missiles that appeared capable of reaching the continental U.S.

Under the resolution’s provisions, all exports of North Korean coal, iron, iron ore, lead, lead ore and seafood will be prohibited. The resolution also imposes new restrictions on North Korea’s Foreign Trade Bank and bans the country from increasing the number of workers it sends abroad.

Those workers’ earnings are an important source of foreign revenue for Kim’s cash-starved autocracy. Human rights advocates have criticized his exploitation of their toil as slave labor.

The Security Council vote was held against the backdrop of mixed signals by the Trump administration on how to deal with North Korea, which has remained in a suspended state of war with the U.S. since the Korean War armistice in 1953.

Even as Secretary of State Rex W. Tillerson signaled recently that the U.S. did not want to pick a fight with Kim and was not interested in regime change, the U.S. military tested an intercontinental ballistic missile and conducted military drills with South Korea.


On Saturday, Tillerson arrived in the Philippines for a meeting with the Association of Southeast Asian Nations. His counterparts from North and South Korea will also attend.

While it appeared unlikely that Tillerson would meet with Foreign Minister Ri Yong Ho of North Korea, there was a possibility that Ri would meet with South Korea’s new foreign minister, Kang Kyung-wha.

If an opportunity “naturally occurs, we should talk,” Kang said on Saturday when she arrived in Manila, news agencies reported.
