Chinese President Xi Jinping offered high praise to visiting North Korean leader Kim Jong Un on Tuesday, lauding the "positive” outcome of his historic summit with U.S. President Donald Trump and promising unwavering friendship.

Meeting Kim on his third trip to China this year, and just a week after Kim met Trump in Singapore on June 12, Xi said China was willing to keep playing a positive role to promote the peace process on the Korean peninsula.

Kim’s visit was the latest in a flurry of diplomatic contacts, and unlike during his previous two visits to China, the government announced his presence while he was in the country rather than waiting for him to leave.

Xi told Kim he was very happy to see the "positive” outcome of his meeting with Trump, and the important consensus reached on denuclearisation and setting up a lasting peace mechanism, according to Chinese state television.

"No matter the changes in the international and regional situation, China’s party and government’s resolute position on being dedicated to consolidating and developing Sino-North Korea relations will not change,” the report cited Xi as saying.

"The Chinese people’s friendship for the North Korean people will not change, and China’s support for socialist North Korea will not change,” Xi added.

Kim told Xi he hoped to work with China and other parties to push the peace process, Chinese state television said.
