The foreign ministry issued a statement late Tuesday praising the "positive outcomes" of a meeting between South Korean envoys and North Korean leader Kim Jong Un in Pyongyang.
The two countries agreed to hold a summit between Kim and South Korean President Moon Jae-in in the Demilitarized Zone in late April, according to Seoul.
Pyongyang was also said to be ready to halt nuclear and missile tests, and consider the dramatic step of abandoning costly and controversial WMD programmes if the United States agrees not to attack or overthrow the regime.
"We hope that the DPRK and the ROK can earnestly implement the relevant consensus and continue with their efforts to advance reconciliation and cooperation," Chinese foreign ministry spokesman Geng Shuang said in the statement, using the acronyms of the North and South.
"We hope that all relevant parties can seize the current opportunity, work for the shared goal and make concerted efforts to promote the process of denuclearisation of the Peninsula and politically resolving the Korean Peninsula issue," Geng said.
"China is willing to continue to play its due role to this end."
Earlier on Tuesday, before the landmark announcement, Geng had told reporters that "interactions" between North and South Korea "should be expanded" to include the United States.
Calling the statements coming out of both Seoul and Pyongyang "very positive," Trump refused to rule out a historic meeting with Kim.
"We have come a long way at least rhetorically with North Korea," Trump said. "It would be a great thing for the world, it would be a great thing for North Korea, it would be a great thing for the peninsula, but we will see what happens," he said in the Oval Office.
"We are going to do something, one way or the other, we are going to do something and not let that situation fester," Trump said, in a reference to the standoff over Pyongyang's nuclear ambitions.
The breakthrough should please Beijing as the Asian superpower, fearing a conflict at its border, has repeatedly called for negotiations to resolve the nuclear crisis.
China has also urged the United States, Japan and South Korea to suspend joint military drills in the region in return for North Korea to halt its nuclear activities.
