NKorean envoy delivers letter to China's Xi

A top North Korean envoy delivered a letter from leader Kim Jong Un to Chinese President Xi Jinping on Friday as part of efforts to mend fences after Pyongyang angered Beijing with recent snubs and moves to develop its nuclear program.

The official China News Service said North Korean Vice Marshal Choe Ryong Hae delivered the handwritten letter from Kim to Xi at an afternoon meeting at the Great Hall of the People in central Beijing. It gave no details about the letter's contents.

The meeting followed an unusual half-year gap in high-level contacts during which Pyongyang angered Beijing by conducting rocket launches, a nuclear test and other saber-rattling - spiking tensions with South Korea and the U.S.

Beijing considered the moves an affront to its interests in regional stability and showed its displeasure by joining with the U.S. to back U.N. sanctions and cut off dealings with North Korea's Foreign Trade Bank.

North Korea also frustrated Beijing by refusing to agree to high-level meetings and incensed the Chinese public this month with the detention of a Chinese fishing crew.

"The relationship is rocky, so they will try to mend the relationship," Cui Yingjiu, a retired professor of Korean at Peking University, said of North Korea. "Second, they also want to improve relations with the U.S. and need China to be their intermediary."

Choe's three-day visit to Beijing came ahead of a meeting in California early next month between Xi and President Barack Obama, as well as a trip to Beijing by South Korean President Park Geun-hye in late June.

China is North Korea's last significant diplomatic ally and main source of trade and economic assistance. Ties between their insular communist governments have always been wrapped in secrecy and it is not clear whether the contents of Kim's letter to Xi will ever be revealed.

China is believed to have agreed to Choe's visit only after Pyongyang committed to returning to the process of negotiation, and required him to state that publicly twice before his meeting with Xi.

Earlier Friday, a top Chinese general told Choe that Beijing wanted a peaceful, denuclearized Korean Peninsula, in a reiteration of China's established position that could also be seen as a rebuke to the North.

The official state Xinhua News Agency quoted Fan Changlong as telling Choe that tensions surrounding the nuclear issue have "intensified strategic conflicts among involved parties and jeopardized the peace and stability of the peninsula."

Xinhua quoted Choe as telling Fan that there is "no guarantee of peace" but his country was "willing to work with all sides to search for a method of solving the problems through dialogue," Choe said.

On Thursday, Choe told the ruling party's fifth-ranked official that North Korea "is willing to accept the suggestion of the Chinese side and launch dialogue with all relevant parties."

John Delury, a professor at Yonsei University in Seoul who specializes in China and North Korea, said the fact that Kim's envoy "is being quoted as saying that North Korea is open to China's suggestions already is a strong signal of kiss and make up."

"This trip is moving things back to a regular strategic dialogue," he said.
