China needs seat at the table with U.S., Koreas during nuclear talks

In truth, Trump needs Xi as much as Kim does. The heads of state of the U.S. and North Korea have never before engaged in talks, and the two countries are clearly not on anywhere near the same page. The North Korean problem is not a bilateral issue, so China's involvement at some point will be inevitable. It only makes sense, then, to keep China involved in the process early on rather than deal with complications arising from a later intervention.

What's next: Kim’s visit to Beijing should be followed up by four-party talks between the two Koreas, the U.S. and China — after his meetings with Moon later this month and with Trump soon afterward. Although Japan and Russia will demand seats at the table, this tighter framework will help narrow gaps among the primary stakeholders. Ironically, the four players who together determined the unfortunate fate of the Korean peninsula in 1953 might be destined to work together again, this time for the good.
