China said Wednesday North Korean leader Kim Jong Un pledged to denuclearize the Korean peninsula during a historic meeting in Beijing with President Xi Jinping, who promised China would uphold its friendship with its isolated neighbor.
After two days of speculation, China and North Korea both confirmed Wednesday that Kim had visited Beijing and met Xi during what China's 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.
North Korea's KCNA news agency made no mention of Kim's pledge to denuclearize, or his anticipated meeting with U.S. President Donald Trump that is planned for some time in May.
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 denuclearization 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.
North Korea is willing to talk with the United States and hold a summit between the two countries, he said.
"The issue of denuclearization of the Korean Peninsula can be resolved, if South Korea and the United States respond to our efforts with goodwill, create an atmosphere of peace and stability while taking progressive and synchronous measures for the realization of peace," Kim said, according to Xinhua.
Though billed as an unofficial trip, Kim's appearance in Beijing contained almost all the trappings of a state visit, complete with an honor guard and banquet at Beijing's Great Hall of the People.
Kim and Xi also met at the Diaoyutai State Guest House, where Kim's grandfather, Kim Il Sung, planted a tree in 1959 that still stands to this day.
State television showed pictures of the two men chatting amiably and Kim's wife, Ri Sol Ju, getting an equally warm welcome from Xi's wife, Peng Liyuan.
China briefed Trump on Kim's visit and the communication included a personal message from Xi to Trump, the White House said in a statement.
"The United States remains in close contact with our allies South Korea and Japan. We see this development as further evidence that our campaign of maximum pressure is creating the appropriate atmosphere for dialogue with North Korea," the statement said.
Analysts and former negotiators remain deeply skeptical Kim is willing to give up the nuclear weapons his family has been developing for decades.
Kim told a banquet hosted by Xi the visit was intended to "maintain our great friendship and continue and develop our bilateral ties at a time of rapid developments on the Korean peninsula", according to KCNA.
