North Korean Deputy Foreign Minister Choe Son-hui said the US "betrayed" and would be responsible if the opportunity for negotiations between the two countries collapsed.

Ms. Choe Son-hui's statement was published by the Korean news agency Yonhap today. Diplomat Choe, a close aide to North Korean leader Kim Jong-un, is visiting Moscow, Russia, but it is unclear where and when the statement was made.

The North Korean Deputy Foreign Minister also affirmed that Pyongyang had taken all actions to build trust with Washington, but all they received was betrayal.

Earlier, US special envoy for North Korea Stephen Biegun was also concerned about the talks between the two countries, saying that Pyongyang's "year-end deadline" was false, that they could provoke it when the deadline ended.

President Kim Jong-un announced a "year-end deadline" in April, which requires the US to lift sanctions that hinder the Korean economy. This has raised concerns that if the two countries' negotiations fail to make significant progress, Pyongyang may continue testing long-range and nuclear missiles after a two-year delay.

North Korea has also repeatedly stated it is not "interested" in talks with Washington, unless it ends a "hostile" policy. Since the beginning of this year, North Korea has repeatedly tested rockets, apparently to warn the US about the weapons it is developing.

After the collapse of the US-Dynasties negotiations in Stockholm, Pyongyang repeatedly accused Washington of inappropriate and threatening approaches if this did not improve, relations between the two countries "could end." right away".
