South Korean envoys are visiting Japan, China and Russian Federation to brief the countries on planned inter-Korean talks and a meeting between North Korea's leader Kim Jong Un and US President Donald Trump.
Meeting with Xi at the Great Hall of the People in Beijing, Chung Eui-yong said the situation on the Korean Peninsula had "undergone very positive changes".
Suh Hoon, chief of South Korea's spy agency, was also visiting Japan to brief officials there on the progress in talks.
Chung expressed thanks for China's role at a meeting earlier with China's top diplomat, State Councillor Yang Jiechi.
China looks forward to smooth talks between the two Koreas and between the United States and North Korea and substantive progress in the denuclearization process and normalization of ties, Xi added.

South Korea will "deploy all possible means" to respond to U.S. President Donald Trump's decision to impose tariffs on steel and aluminium imports, the country's finance minister said on Monday.
Trump agreed on Friday to meet with Kim Jong-un by the end of May and the two Koreas are due to hold their own summit by the end of April.
On Sunday, South Korean media quoted a presidential office source as saying the US-North Korean summit may take place, like the inter-Korean talks, at the South's facility in the Panmunjom truce village.
Rhetoric in the North's state media has been tame, however, compared to threats a year ago that went as far as saying Pyongyang would fire missiles into the vicinity of the US territory of Guam if provoked.
