Security was tight at the Beijing airport where paramilitary police prevented journalists from shooting photos. Gawking pedestrians watched the passing motorcade, which included Kim's limousine - a black Mercedes with gold emblems on the rear doors - as well as several minibuses and 15 motorcycle police clad in white suits.
Roads near the Diaoyutai State Guesthouse, where senior Chinese officials meet with visiting leaders, were being closed and a motorcade with motorcycle escorts was seen heading into the compound. Prior to the Singapore summit, Trump had complained that the North Koreans' attitude changed after Kim and Xi met in Dalian.
While Washington insists there will be no sanctions relief until North Korea denuclearizes completely, China may be willing to work with Kim well before that.
Mr. Kim promised Mr. Xi close cooperation in securing "true peace" and the "opening a new future" on the Korean Peninsula, reported the North's state-run Korean Central News Agency.

For 17 years, Hyeonseo Lee lived under the thumb of the brutal and isolated regime in North Korea.

"The momentum for dialogue and easing of situation on the Korean Peninsula has been effectively strengthened", Xi said.

The second day of Kim's visit to Beijing was all about economic tutelage.
China has touted the prospects of more trade and investment if North Korea makes progress in talks on abandoning its nuclear weapons and long-range missile programs. If not, verification will have to rely on DNA analysis according to very strict protocols observed by the USA military for missing soldiers.
Trump has repeatedly made clear his intention to avoid insulting Kim Jong Un in the days since the summit, most evident in his push to halt what he called "provocative" joint military exercises with South Korea. When the United Kingdom complained in 2011 that the alleged remains of a British fighter pilot were not a pilot, British, or human, the North Korean military replied, "Too bad".
Some lawmakers and experts said the North received a major concession - reversing decades of US military posture in the region, with joint exercises at the heart of readiness efforts against the rogue regime - while the United States seemingly receiving nothing in return.More news: Now with Time Warner, AT&T starts streaming TV service
