North Korea on Tuesday canceled talks with South Korea scheduled for Wednesday, and threatened to cancel next month’s summit between President Donald Trump and dictator Kim Jong-Un.
North Korea cited joint U.S.-South Korea military drills as reason for the dramatic change in tone, according to South Korean news agency Yonhap.
Only last week, North Korea released three American prisoners and promised to start dismantling a nuclear test site as part of efforts to lay the groundwork for talks with Trump.
It was not clear whether Trump would bow to Mr Kim’s demand to cancel the drills.
