South and North Korea's top nuclear envoys met Friday in what diplomats said could be an attempt to revive stalled six-nation talks aimed at ending the North's nuclear weapons programme, media reports said, according to dpa. North Korea's Ri Yong Ho and South Korea's Wi Sung Lac held talks ahead of the Association of South-East Asian Nations (ASEAN) Regional Forum, the Asia-Pacific's largest security forum, in Bali, Indonesia, the Yonhap News Agency reported, citing South Korean diplomatic sources. "It is the first time that chief nuclear envoys of South and North Korea have held a bilateral meeting on nuclear issues," an unnamed South Korean diplomat told the agency. The diplomat said the talks between Wi and Ri were aimed at clearing the way for the North and South Korean foreign ministers to meet. North Korean Foreign Minister Pak Ui Chun said Friday that Ri would be the North's envoy to the currently stalled six-party talks. The six-party talks - involving South Korea, North Korea, Japan, China, the United States and Russia - have been on hold since December 2008. All six are among the 26 countries to be represented at the ASEAN Regional Forum on Saturday on Bali. North Korea has been under international pressure to give up its nuclear weapons programme. -- SPA
