North Korea denounced U.S. Calls for enforcing international sanctions despite its goodwill moves and said progress on denuclearization promises could not be expected if Washington followed an “outdated acting script.”

The north’s official released a statement saying “as long as the U.S. Denies even the basic decorum for its dialogue partner and clings to the outdated acting script which the previous administrations have all tried and failed, one cannot expect any progress in the implementation of the north Korea-U.S. Joint statement including the denuclearization.”

The ministry also said pyongyang had stopped nuclear and missile tests, dismantled a nuclear test ground and returned the remains of some U.S. Soldiers killed in the 1950-53 Korean war. Yet Washington was still insisting on “denuclearization first” and had “responded to our expectation by inciting international sanctions and pressure.

The statement added North Korea was still willing to implement a broad agreement made at a landmark June 12 summit between U.S. President Donald Trump and North Korean leader Kim Jong Un.
