The US did not see "any breakthroughs" in Monday's drafting process of a joint document for the six-party talks on the Korean nuclear issue, said US chief negotiator Christopher Hill last night.

"We will stay here as long as we feel we are making progress," Hill said, refusing to give any specific description of the final document.

Having worked for 12 hours yesterday, Hill indicated that the talks would last for "days like this."

Earlier on Monday, Hill told reporters that the process of consultations on the drafting of a joint document was "rather well" though there was "difference on language."

It was reported that China presented on Sunday night the second version of the draft document to all delegations to this round of talks, and deputy heads of all parties discussed the drafting issue yesterday.

The six-party talks inched into the seventh day Monday. Chief negotiators from the six nations had shuttle contacts for in-depth discussions on the wording of the draft document yesterday morning. Deputy negotiators met in the afternoon to hold working-level consultation on the second version of the draft, said a member of the Chinese delegation.
