REPUBLIKA.CO.ID, GENEVA -- North Korea on Friday ruled out negotiations with Washington as long as joint U.S-South Korea military exercises continue, and said that Pyongyang's atomic weapons programme would remain as a deterrent against a U.S. nuclear threat.

In an interview with Reuters, Han Tae Song, North Korea's ambassador to the United Nations in Geneva, brushed off the new sanctions which the Trump administration has said it is preparing, as well as the possibility of North Korea being added to a U.S. list of states sponsoring terrorism.

South Korea and the United States agreed on Friday to keep working for a peaceful end to the North Korean nuclear crisis, but a U.S. envoy said it was difficult to gauge the reclusive North's intentions as there has been "no signal".

Han, asked about those bilateral talks in Seoul, replied: "As long as there is continuous hostile policy against my country by the U.S. and as long as there are continued war games at our doorstep, then there will not be negotiations."
