"I am delighted that South Korea's efforts have made great progress in the overall Korean Peninsula situation and that close dialogue between NK and the United States has been achieved".
While China remains North Korea's only ally and main economic lifeline, relations between the two neighbours have soured as Xi, under pressure from Trump, has backed a slew of United Nations sanctions to punish Pyongyang for its nuclear and missile tests.
A White House statement said Xi had welcomed to prosper of talks during a call with Mr Trump on Friday.
Any summit in North Korea - even outside Pyongyang - is seen as a long-shot as any Trump visit would risk similarly unfavourable criticisms of the American president.
Chinese State Councilor Yang Jiechi said, "China commits itself to the efforts of realizing denuclearization of the Korean Peninsula, maintaining peace and stability... and resolving things through dialogue and negotiation". Then at 3:30, they got together with other U.S. government officials, including U.S. Secretary of Defense James Mattis, and Director of National Intelligence Dan Coats. Noah asked. "What if he goes to North Korea, doesn't say anything racist, even bonds with Kim because they go to the same Supercuts, and then they reach an historic agreement to get rid of North Korea's nukes, that would be awesome!"
North Korea's state media have lauded the thaw in relations with South Korea.
China looks forward to smooth talks between the two Koreas and between the United States and North Korea and substantive progress in the denuclearisation process and normalisation of ties, Mr Xi added.
Kim has yet to publicly confirm his invitation to meet with Trump in a bid to defuse a standoff over Pyongyang's nuclear programme, and officials in Seoul and Washington say the exact location and timing of any summit remain to be determined.
The U.S. and the South Korea are also discussing how to conduct upcoming military drills in a way that won't provoke Kim, whose regime views the exercises as a rehearsal for war.
"I'm very anxious about that happening again and I would hope that this administration understands that", he said. China does not want North Korea to acquire nuclear weapons, but it also does not want the regime to change. "I don't think it's that unusual" that we haven't heard from the North Koreans yet. "The South Koreans are clearly heavily involved". Global sanctions against North Korea must be maintained until the complete, verifiable and irreversible scrapping of North Korea's nuclear weapons program is achieved.
Cheong Soeng Chang spoke about the possibility of North Korea giving up its nuclear and missile programs.
