Beijing, Aug 12: Russia today said six-nation North Korean nuclear talks will be at vice ministerial-level in Beijing on August 27-29, although diplomats from other nations said the formalities had yet to be worked out. "The talks will be held on August 27-29, they will be held at the vice ministerial level," a Russian diplomatic source told a newspersons.

Russian Deputy Foreign Minister Alexander Losyukov was expected to attend the meeting, he said. Losyukov was in Beijing yesterday and met with Chinese officials, including Vice Foreign Minister Wang Yi. China and Russia are considered Pyongyang's closest allies.

The meeting will involve North and South Korea, China, the United States, Japan and Russia and follows a first round of three-party talks in Beijing in April.

There has been a flurry of diplomatic activity leading up to the summit in which all sides are expected to discuss how to negotiate the end to North Korea's fledgling nuclear weapons programme, ostensibly in exchange for security guarantees for the Stalinist nation. China's foreign ministry Tuesday refused to confirm any dates saying only that they would be revealed at "an opportune time", although foreign minister Li Zhaoxing said yesterday they would be held in late August.

The South Korean, Japanese, North Korean and US embassies in Beijing said they could not confirm the dates and that such issues were still under discussion.
