The New York Times reports: "There's one leader who may be pleased that President Trump's planned summit meeting with Kim Jong-un, North Korea's leader, appears to be on shaky ground: China's president, Xi Jinping. Analysts in China and the United States say that Mr. Xi is probably nervous about the North Korean leader's getting too close to the Americans, particularly given Mr. Kim's independent streak and past willingness to buck China. But a delay in the meeting also benefits Mr. Xi in another way, allowing him to use his influence with North Korea as leverage while China negotiates a trade deal with Washington. "It is in Xi's interest not only to delay but to have the summit pending for as long as possible," said James Mann, author of "The China Fantasy." "The prospect of a deal without a deal itself gives China leverage over the U.S., especially on trade.""
