North Korean leader Kim Jong-un has said that his country would soon introduce a “new strategic weapon” in the near future, adding that he sees little reason to stick to his country’s suspension of nuclear and long-range missile tests, he had put in place during talks with the US.

Talks between North Korea and the US have stalled with Washington refusing to lift sanctions until Pyongyang fully abandons its nuclear programme. Speaking at a party meeting here on Wednesday, Kim said North was no longer bound by the self-declared moratorium, as the US continued joint military drills with South and had stepped up their sanctions.

“Under such condition, there is no ground for us to get unilaterally bound to the commitment any longer, the commitment to which there is no opposite party, and this is chilling our efforts for worldwide nuclear disarmament and non-proliferation,” state news agency KCNA quoted Kim as saying.

He also threatened that “the world will witness a new strategic weapon” by the North “in the near future”, while giving no further details. In response to the North Korean leader’s latest threats, US President Donald Trump told reporters that he and Kim “did sign a contract, talking about denuclearisation”.
