Negotiators in the six-party talks on the Korean peninsula nuclear issue reached a "principled consensus" here on Friday on verifying the declaration of the Democratic People's Republic of Korea (DPRK), a Chinese official said Friday.

The top negotiators discussed the specific principles of setting up a verification and inspection mechanism, as well as economic and energy aid to the DPRK, the Chinese delegation's spokesman, Qin Gang, told reporters.

"The six parties achieved some progress on the verification mechanism, reaching a principled consensus," Qin said, without elaborating. "The specific consensus will be announced very soon."

Negotiators also exchanged views during Friday's talks on establishing the peace and security mechanism in northeast Asia.

In addition, the working groups on denuclearization and economic and energy aid held meetings, mapping out measures to implement the consensus reached by the heads of the delegations, Qin said.

The current session of talks entered a second day Friday at the Diaoyutai State Guesthouse in Beijing.

The fresh discussions came after the DPRK handed over the long-awaited nuclear declaration list in late June and then blew up a cooling tower in its main nuclear reactor at Yongbyon.

The talks, which group China, the United States, the DPRK, the Republic of Korea, Russia and Japan, are scheduled to run for three days.
