"In a word, Chairman Kim Jong Un's visit to China is an indication that the second North Korea-U.S. summit is drawing near", Moon said.
Like his father - Kim Jong-il, who ruled North Korea from 1994 to 2011, Kim's strength has always been his "vagueness" about what he'll do next, and an ability to "keep everybody guessing until they do it", said James Kim.
Trump is seeking a second summit with Kim to re-energize talks that have made little headway since their first meeting in June, saying Sunday a date would be announced "in the not-too-distant future".
South Korea's Yonhap News Agency said Kim visited a technology development zone on the outskirts of Beijing on Wednesday and spent around 20-30 minutes touring a factory run by famed traditional Chinese medicine maker Tong Ren Tang.
"The Korean peninsula situation has been easing since a year ago, and China's important role in this process is obvious to all ... the DPRK side highly and sincerely appreciates the Chinese efforts", Kim said.
China is the North Korea's sole major ally and key trade partner.
If Xi Jinping has lit a fire under Kim's butt to bring him back to the table and start tearing down his warheads and missles, he may wind up doing us a far bigger favor than any new trade deal.
In a related development on Thursday, South Korean Prime Minister Lee Nak-yon said at a government meeting that there are views in his country that Japanese leaders have been fanning anti-South Korea sentiment among Japanese people for political purposes, according to the Prime Minister's Secretariat.
The schedule and route this time was similar to Kim's first trip to Beijing by train last March.

In a New Year's address, Kim pledged his commitment to complete denuclearization in a message to Washington and expressed his desire to meet again with Trump - a sentiment immediately reciprocated by the US president over Twitter.
But China, perhaps hesitant to sour relations with Washington amid a bruising trade war between the world's two biggest economies, may also be hoping to extract something from Kim's visit.
Xi greeted Kim at Beijing's ornate Great Hall of the People on Tuesday - believed to be the North Korean leader's birthday - before hosting a welcome banquet for Kim and his wife Ri Sol Ju.
As VOA's Bill Gallo reports, the North Korean leader may be hoping to use the visit to increase his leverage with Washington.
The Chinese Foreign Ministry said on Kim's visit that the two countries are committed to deepening bilateral relations, properly resolving the Korean Peninsula issue, and maintaining peace and stability on the region.
"China has always supported both sides to continue to hold talks and to reach a positive outcome", Lu said.
"The Sino-US trade negotiations are a matter between China and the US", he said.
Conditions for resuming two key economic projects between North and South Korea - the Kaesong Industrial Complex, where Southern companies used to employ North Korean workers, and Southern tourism to Mount Kumgang in the North "have essentially been met already", he said. "This means that China implemented the United Nations resolution well", he said.
The site that Kim and Trump will pick for the next meeting has been attracting keen attention, especially after President Moon Jae-in said Thursday the summit will take place soon and Trump said that the USA is "negotiating a location" on Sunday.
