Negotiators to the fourth round of the six-party talks on the Korean Peninsula nuclear issue will work on final revision of the draft joint document, sources quoted an official with the Russia delegation in Beijing Sunday.

V. Yermolov, deputy head of the Russian delegation, was quoted as saying that the delegations have made consultations on the draft joint document in "a constructive atmosphere" on Sunday.

He said that after the delegations each revised the draft that the Chinese delegation presented, they fed the revised version back to China Sunday.

The fourth round of the six-party talks has entered into the sixth day, and though no concrete progress has been disclosed, all parties have agreed to work out a joint document to sum up the developments.

Although it was weekend, all delegations were busy in the Diaoyutai State Guesthouse on discussing the draft joint document, according to Chinese delegation.

The heads of the six delegations to the talks agreed at their meeting Saturday morning that a joint document would be issued to record the results of this round of talks. The Chinese delegation presented a draft at the meeting.

The US delegation, a major participant in the talks, described the draft as representing "a good basis" for "future negotiations and future discussions" and for "final document and final agreement."

As for whether the joint document could come out Sunday, Christopher Hill, US delegation head and US assistant secretary of state, said, "We know it takes time."

On Sunday, Song Min-soon, chief negotiator of the Republic of Korea (ROK), said it was hard to tell when the ongoing nuclear talks would conclude, but all sides agreed to establish a framework for the denuclearization of the Korean Peninsula.

All sides had agreed to reach an agreement that would embody the core contents of the talks through cooperation, he added.
