US Special Representative for Democratic People's Republic of Korea (DPRK) Policy Glyn Davies said Thursday that US-DPRK talks in Beijing were "serious and substantive."

"We covered quite a number of issues," Davies said after meeting the DPRK delegation, which was headed by DPRK First Vice Foreign Minister Kim Kye Gwan.

"We are still in the middle of talks with DPRK," Davies said. The envoy did not provide any details of his meeting with the delegation. Media reports said two meetings were conducted on Thursday, starting with a meeting at the DPRK Embassy in Beijing following by a second meeting at the US Embassy.

A number of bilateral talks regarding the Korean Peninsula have occurred in Beijing in recent days.

According to the Foreign Ministry, China's Special Representative for Korean Peninsula Affairs Wu Dawei met in Beijing on Wednesday with Shinsuke Sugiyama, Japan's top envoy to the long-stalled six-party talks.

Dialogue is the best way to resolve the DPRK nuclear issue, Foreign Ministry spokesman Hong Lei said Thursday at a routine press briefing, adding that the six-party talks can effectively address the concerns of all parties and realize the denuclearization of the Korean Peninsula.

China has voiced its support for related parties to improve and develop relations in order to move the talks forward, Hong said.

The six-party talks, which involve the DPRK, the Republic of Korea, the United States, China, Japan and Russia, were launched in 2003, but were stalled in December 2008. The DPRK quit the talks in April 2009.

Former US Special Representative for DPRK Policy Stephen Bosworth met with Kim Kye Gwan twice last year to discuss the possible resumption of the long-stalled talks.
