A senior Pyongyang official is set to deliver a letter to President Donald Trump from North Korean leader Kim Jong Un on Friday amid signs the diplomatic process, while advancing, will be more protracted than the U.S. previously has suggested.
Mr. Trump said he expects to receive a “very positive” letter and Secretary of State Mike Pompeo asserted that “real progress” was made in his meetings with the North Korean official in New York toward setting the conditions for a productive summit meeting.
But in an acknowledgment of the formidable difficulties that remain, Mr. Trump said he may need a second or third meeting with Mr. Kim to reach a final agreement, even if the Singapore summit is held on June 12 as planned, and both he and Mr. Pompeo outlined what could be a lengthy process.
