Chinese Vice Premier Wu Yi will visit Pyongyang next week and plans to discuss with North Korean leaders efforts to end their nuclear-weapons programme, China's foreign ministry said Thursday, according to DPA. Wu will make an "official goodwill visit" to North Korea from October 8 to 11, ministry spokesman Qin Gang told reporters. "During the vice premier's visit, the Chinese and Korean sides will exchange views on bilateral issues and other issues of mutual concern," Qin said. "The nuclear issue on the Korean peninsula is an issue that concerns both China and the Democratic People's Republic of Korea," he said. The visit comes amid uncertainty about North Korea's commitment to principles agreed this month for dismantling its nuclear-weapons and other nuclear programmes. On September 19, North Korea, the United States, China, South Korea, Japan and Russia issued their first joint statement in more than two years of talks aimed at ending Pyongyang's atomic-weapons programme
