China said on Wednesday it won a pledge from North Korean leader Kim Jong Un to denuclearize the Korean peninsula during a meeting with President Xi Jinping, who pledged in return that China would uphold its friendship with its isolated neighbor.After two days of speculation, China announced on Wednesday that Kim had visited Beijing and met Xi during what the official Xinhua news agency called an unofficial visit from Sunday to Wednesday.
The trip was Kim's first known journey abroad since he assumed power in 2011 and is believed by analysts to serve as preparation for upcoming summits with South Korea and the United States.
Beijing has traditionally been the closest ally of secretive North Korea, but ties have been frayed by North Korea's pursuit of nuclear weapons and China's backing of tough U.N. sanctions in response.
Xinhua cited Kim as telling Xi that the situation on the Korean peninsula is starting to improve because North Korea has taken the initiative to ease tensions and put forward proposals for peace talks.
"It is our consistent stand to be committed to denuclearisation on the peninsula, in accordance with the will of late President Kim Il Sung and late General Secretary Kim Jong Il," Kim Jong Un said, according to Xinhua.
