UNITED NATIONS -- 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.
In response, Pyongyang threatened to cancel the 1953 cease-fire that ended the Korean War.
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.
