South Korea, Japan and China reaffirmed standard talking points about the denuclearization of North Korea in a rare trilateral summit on Monday, even as Beijing’s premier remained silent about Pyongyang’s announcement hours earlier that it will soon launch another satellite.

But despite the reiteration of long-standing positions, the DPRK responded angrily to the reference to denuclearization and asserted again that it is a nuclear state, accusing the three countries of infringing on its sovereignty.
