The North has opposed joint military drills conducted by South Korea and the United States, which kicked off last week, calling them a "rehearsal for war" and has fired several short-range missiles in recent weeks.

The loss of dialogue momentum between the North and South and the stalemate in implementing a historic summit between their two leaders last year is entirely the responsibility of the South, a North Korean spokesman said in a statement.

The spokesman repeated criticism that the joint U.S.-South Korea drills was sign of Seoul's hostility against the North.

"As it will be clear, we have nothing more to talk about with South Korean authorities and we have no desire to sit down with them again," the North's spokesman for the Committee for the Peaceful Reunification of the Country said.

Moon and North Korean leader Kim Jong Un have met three times since April last year pledging peace and cooperation but little progress has been made to improve dialogue and strengthen exchange and cooperation.

The North's spokesman said it was "delusional" to think that inter-Korean dialogue will resume once the military drills with the United States are over.

The spokesman left open the possibility of talks with the United States, speaking of upcoming dialogue between the two countries but warned it will have no place for the South.
