BEIJING — China's vice president will visit North Korea this week for Korean War commemorations following a period of strained relations between the communist neighbors.
Vice President Li Yuanchao will be the highest ranking Chinese official to visit North Korea since Kim Jong Un took over as leader of the impoverished hard-line communist state upon his father's death in December 2011.
The trip lasting Thursday through Sunday affirms a warming trend in relations between a deeply isolated Pyongyang and Beijing, its only real ally and key source of economic assistance.
The statement posted Wednesday on the Chinese Foreign Ministry's website said Li will visit for 60th anniversary commemorations of the end of the 1950-53 Korean War, in which China fought on the North's side against U.N. forces led by the United States.
That shared history, in which troops sent by Mao Zedong likely saved the North Korean regime from annihilation, has been the default fallback for the sides through periods of ambivalence bordering on animosity.
Most recently, Beijing was deeply offended by Pyongyang's actions following Kim's ascension, including conducting rocket launches, a nuclear test and other saber-rattling that spiked 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 after a Chinese fishing crew was detained.
