Seoul – North Korea’s leader plans to further develop nuclear programmes and to introduce a “new strategic weapon” in the near future, state media said on Wednesday, although he signalled there was still room for dialogue with the United States.

Kim Jong Un presided over a four-day meeting of top Workers’ Party officials this week amid rising tensions with the United States, which has not responded to his repeated calls for concessions to reopen negotiations. Washington has dismissed the deadline as artificial.

Kim said there were no grounds for North Korea to be bound any longer by a self-declared moratorium on testing nuclear bombs and intercontinental ballistic missiles (ICBM), according to a statement on the results of the policy meeting carried by the official KCNA news agency.

At times smiling or striking the podium with his hand as he made remarks during the meeting, Kim accused the United States of making “gangster-like demands” and maintaining a “hostile policy”, such as by holding continued joint military drills with South Korea, adopting cutting edge weapons and imposing sanctions.

He pledged to continue bolstering his country’s nuclear deterrent but said the “scope and depth” of that deterrent will be “properly co-ordinated depending on” the attitude of the United States.
