South Korea’s Chosun Ilbo daily on Monday cited diplomatic sources as saying the landmark summit will take place in "mid-June". The newspaper on Monday suggested that the possibility of Singapore hosting the meeting had "increased greatly", after a decision by Mr. Trump to host South Korean president Moon Jae-in at the White House later this month.

Mr.Trump had previously suggested that the demilitarised zone between the two Koreas-the site of a recent summit between Kim and Moon-could also be an appropriate venue for his meeting with the North’s leader.
