A six-party working group on denuclearizing the Korean Peninsula met Thursday in China to iron out terms for disabling North Korea's nuclear facilities and to lay out concrete steps for denuclearization.

The six-party negotiators held the first day of a plenary session in Shenyang, Liaoning Province, exchanging views on technical methods for the disablement of Yongbyon's five-megawatt experimental reactor and reprocessing facilities.

In an opening speech, China's chief nuclear negotiator Wu Dawei called on his counterparts to "create energy for progress in denuclearization."

Prior to the session, South and North Korean negotiators held a two-way meeting to discuss ways to link the second phase of North Korea's denuclearization measures to the provision of 950-thousand tons of heavy fuel oil.

The South Korean envoy also met with his Chinese counterpart, while chief U.S. envoy Christopher Hill met separately with his Russian and Japanese counterparts one-on-one.
