U.S. President Donald Trump took to Twitter on Sunday to serve up the dubious claim that North Korea has "agreed to denuclearization" ahead of his meeting with Kim Jong Un — an assertion at odds with what the White House has previously said and something Pyongyang has yet to say publicly.

Kim announced over the weekend that his country had suspended nuclear and longer-range missile tests and shut down its main atomic test site, saying that it would now shift its focus to shoring up its sanctions-hit economy.

There was no mention of it relinquishing its nuclear arsenal.
