BEIJING, Feb. 10 (Xinhua) -- Envoys to the six-party talks will be pulling out all stops this weekend in an effort to nail down the first steps toward denuclearizing the Korean Peninsula.

The envoys on Friday discussed a draft document and as negotiations enter the third day on Saturday they will endeavor to nail down specifics on the initial steps required to implement a 2005 statement.

Chief U.S. negotiator Christopher Hill said "it is basically one or two items, probably best described as one item", urging the Democratic People's Republic of Korea (DPRK) to take a further step toward a "multilateral agreement."

However, Russian representative Alexander Losyukov, when leaving for talks Saturday morning, said the talks will end with a two-page joint statement.

China is expected to work out a revised proposal based on the draft after Friday's consultations. The revisions will cover the issues of how working groups operate, and how to provide aid to the DPRK, provided consensus is reached, Losyukov said.

"The DPRK is very concerned about the wording of the joint statement," said Losyukov.

Losyukov hinted Friday night that the talks might end before Monday.

"The talks will enter a difficult stage today," said Japanese negotiator Kenichiro Sasae on Saturday, adding that China would work out a revised version of the draft based on Friday's consultations and the parties would have further discussions.

"All parties want to reach an agreement but we need to make greater efforts," Sasae told reporters as he left his hotel.

Reports said the draft agreement proposed halting within two months work at nuclear sites in the DPRK, including the Yongbyon reactor, and supplying Pyongyang with alternative energy sources.

Chief Republic of Korea (ROK) negotiator Chun Yung Woo voiced his caution about the possible deal as the negotiators began to address the "core items" of the Chinese draft proposal.

"It's hard to say whether an agreement will be reached, although all the parties are narrowing down their differences," Chun told reporters.

"Today and tomorrow will be decisive," Chun said.

After a 48-day recess, the negotiators gathered again in Beijing on Thursday to explore the first steps in implementing the 2005 statement.

In the September 2005 joint statement, the DPRK agreed to abandon its nuclear program in exchange for economic aid and security guarantees.
