North Korea threatens to stall denuclearization in warning to US

North Korea on Thursday denounced US calls for enforcing global sanctions despite its goodwill moves and said progress on denuclearization promises could not be expected if Washington followed an "outdated acting script".

"We hoped that these goodwill measures would contribute to breaking down the high barrier of mistrust existing between the DPRK and the USA and to establishing mutual trust".

The United States has led the sanctions campaign to press North Korea to give up its nuclear and missile programs.

The ministry threatened to hold back on denuclearization "as long as the USA denies even the basic decorum for its dialogue partner and clings to the outdated acting script which the previous administrations have all tried and failed", according to a spokesperson quoted by the North's state-run KCNA news agency.

But it accused unidentified high-level USA officials of "going against the intention of President Trump" by 'making baseless allegations against us and making desperate attempts at intensifying the global sanctions and pressure'.

Amid a lack of progress on North Korea's denuclearization and recent reports of the country evading sanctions, the United States has stepped up calls for tighter enforcement of the sanctions.

The statement said North Korea was "astonished" to hear Guterres' remarks "at a time when the world supports and welcomes the historic DPRK-US summit and the joint statement in Singapore".

The announcement by an official at the South's Unification Ministry, which handles inter-Korean issues for Seoul, comes amid attempts by Washington and Pyongyang to follow through on nuclear disarmament vows made at a summit in June between President Donald Trump and Kim.

The ministry added that expecting "any result" to negotiations in this context was "indeed a foolish act that amounts to waiting to see a boiled egg hatch out".

However, many used the same clip to point out that criticizing "Fox & Friends" for praising Kim but not other news sources were hypocritical.
