On Tuesday, Kim and Chinese President Xi Jinping met for about an hour to discuss the looming North Korea-US summit, which is expected to take place this month or next.
Kim reportedly said North Korea "will continue sticking to the stance of denuclearization and resolving the Korean Peninsula issue through dialogue and consultation, and make efforts for the second summit between (North Korean) and USA leaders to achieve results that will be welcomed by the worldwide community". Keeping in mind that China is North Korea's only solid, powerful ally and Kim relies on them for much of his sputtering economy, Xi Jinping has significant leverage over North Korea.

The remark by Xi, during a meeting with Kim this week in Beijing, hinted at the depth of the differences that remain between Pyongyang and Washington after Trump and Kim pledged to work towards denuclearisation at their landmark summit in Singapore in June.
