All the parties involved in talks on the Korean Peninsula nuclear issue will work together Sunday on the drafting of a joint document, said an official of the Japanese delegation to the ongoing six-party talks in Beijing.

As the fourth round of the six-party talks entered into the sixth day Sunday, the parties would embark on a working-level discussion over the draft of a joint document in the morning.

The Chinese side presented the text of a draft joint document at the meeting of a delegation heads Saturday morning.

US chief delegate Christopher Hill said Saturday night, "The Chinese text represents a good basis for future negotiations and future discussions."

It also served as "a good basis for final document and final agreement," said the US assistant secretary of state.

Hill said every party involved was working on the joint document, but "We know it takes time," and it was hard for the document to come out Sunday.
