U.S. Hits Obstacle in Getting a Vote on North Korea

The United States pressed for a Saturday vote on a Security Council resolution that would impose sanctions on North Korea for its reported nuclear test, but questions from China and Russia on Friday evening cast the timing and possibly the content of the document into doubt.

The terms of the resolution had already been softened three times this week to meet objections from China and Russia, and earlier Friday there appeared to be agreement on holding a vote Saturday morning.

John R. Bolton, the American ambassador to the United Nations, said the new problems appeared “technical” rather than “substantial,” but said they would require another conference of Japan and the five permanent Council members, Britain, China, France, Russia and the United States, Saturday before the full 15-member panel met later in the day.

While the wording of the resolution was still being worked out, American intelligence officials said on Friday evening that they had found radioactive material in air samples taken over the region, providing more evidence that North Korea did indeed detonate a nuclear bomb.
