North Korea's state media slammed the US for an "evil" attempt to maintain sanctions against Pyongyang.

Iran Press/Asia: By accusing President Donald Trump of blocking progress in inter-Korean relations, North Korea's state media reported that Washington was playing a "double game".

Washington was playing a "double game", said a lengthy commentary carried by the North's official KCNA news agency( Korean Central News Agency ), and was "little short of destroying" the rare diplomatic opportunity between the two.

"Hostile policy and reciprocity can not go together," it said, and negotiations would not move forward "an inch with an obstacle called sanctions".

"The US... is responding to good faith with evil," it added.

In Aug. 28, North Korea warned US that talks on nuclear disarmament are in jeopardy after the United States pulled out of a planned visit to discuss the process.

Officials in Pyongyang sent a letter declaring the negotiations were "again at stake and may fall apart”.

The letter was delivered directly to US Secretary of State Mike Pompeo and said North Korean leader Kim Jong-un's government now felt plans to disarm could not move forward.

The declaration threatens to upset the negotiations between Washington and the nuclear-armed North, in which US President Donald Trump is expected to hold a second summit soon with Pyongyang's leader Kim Jong Un.

Meanwhile, the Republic of Korea (ROK) and the Democratic People's Republic of Korea (DPRK) kicked off high-level talks on Monday in the border village of Panmunjom.

The Korean Peninsula remains in a technical state of war as the three-year war ended with an armistice.

The rapprochement on the Korean peninsula was triggered earlier this year when North Korean leader Kim Jong Un decided to send athletes, cheerleaders and his sister as an envoy to the Winter Olympics in the South.

South Korea has dismissed concerns that it is opening up to the North too quickly, and that it should insist on more concrete steps toward denuclearization in return.
