United Nations ? The United States and Japan on Friday insisted that the Security Council vote within one day on a proposed resolution condemning North Korea’s missile tests, despite an apparent deadlock with China and Russia over the document.

After a second day of negotiations, Japan circulated a new draft text that sought to bridge the differences with China. But Chinese Ambassador Wang Guangya said it contained unacceptable language and threatened to veto the draft.

The split, he said, had to do with one key issue: how much authority to give the council if North Korea doesn’t obey demands to halt its missile program.

“I think I would be forced to vote in a way which means there would be no action by the council,” he said.

The latest draft, obtained by The Associated Press, retains demands that North Korea suspend its ballistic missile program and includes mandatory sanctions, requiring all member states to block it from receiving or selling missile technology.

In an apparent attempt to placate China, the draft narrows the legal authority under which the council could act. It does so by essentially erecting another hurdle on the road to the council using military force if North Korea fails to meet the resolution’s demands.
