UNITED NATIONS (AP) - The world moved closer to punishing North Korea for its latest nuclear test Tuesday as the United States introduced a draft resolution, backed by China, with new sanctions aimed at reining in Pyongyang's nuclear and ballistic missile programs and preventing their export to other countries. The draft resolution would subject North Korea "to some of the toughest sanctions imposed by the United Nations," U.S. Ambassador Susan Rice told reporters. She called the scope of the sanctions "exceptional." The proposed resolution, worked out by Rice and China's U.N. Ambassador Li Baodong over the last three weeks, reflects the growing anger of the U.N.'s most powerful body at North Korea's defiance of three previous sanctions resolutions that demanded a halt to all nuclear and missile tests. This one pledges additional measures if Pyongyang keeps ignoring the council with new tests, Rice said. North Korea's latest test was in February. With the support of China, the North's closest ally, the proposed resolution is not expected to face serious opposition, though council members will send it to their capitals for review. "We hope for unanimous adoption later this week," Rice said. The draft resolution targets for the first time the illicit activities of North Korean diplomats, the country's illicit banking relationships and its illegal transfers of bulk, Rice said. It also adds new travel restrictions. Hours before the U.N. meeting, and as word emerged of the U.S.-China proposal, Pyongyang threatened to cancel the 1953 cease-fire that ended the Korean War. The swift, unanimous response set the stage for a fourth round of sanctions. In addition to barring North Korea from testing or using nuclear or ballistic missile technology, they also ban it from importing or exporting material for these programs. North Korea's neighbors and the West condemn the North's efforts to develop long-range nuclear missiles capable of hitting the United States as a serious threat to Northeast Asia's delicate security and a drain on the precious resources that could go to North Korea's largely destitute people. North Korea says its nuclear program is a response to U.S. hostility that dates back to the Korean War, which ended with an armistice, not a peace treaty, leaving the Korean Peninsula still technically in a state of war. U.S. Secretary of State John Kerry said President Barack Obama and the American people would like to see North Korean leader Kim Jung Un promote peace and engage in talks. "Rather than threaten to abrogate and threaten to move in some new direction, the world would be better served ... if he would engage in a legitimate dialogue, legitimate negotiations, in order to resolve not just American concerns, but the concerns of the Japanese and the South Koreans and the Russians and the Chinese, everybody in the region," Kerry said in Doha, Qatar. That's our hope.
