USA officials, according to North Korea, "are making baseless allegations against us and making desperate attempts at intensifying the global sanctions", against what they believe to be Trump's intentions to better relations between the two countries.
The main agenda item is likely to be planning for the third meeting between South Korean President Moon Jae-in and North Korean leader Kim Jong-un this year.
North Korea said in a statement on Thursday that "some high-level officials within the USA administration" were making "desperate attempts at intensifying the worldwide sanctions and pressure".
"However, the US responded to our expectation by inciting global sanctions and pressure against the DPRK", it said in a statement carried by KCNA news agency.
The White House and US State Department did not immediately respond to requests for comment.
The foreign ministry said that despite their efforts to work with the USA - by stopping their missile launches and nuclear tests - America continues to insist on "denuclearization first", and continues to encourage worldwide sanctions against the North. "North Korea has not taken the steps we feel are necessary to denuclearise". Those followed contentious remarks last week by U.S. Secretary of State Mike Pompeo and North Korean Foreign Minister Ri Yong Ho on the sidelines of a regional summit in Singapore.

North Korea appears to continue dismantling a rocket launching site, a US think tank said, based on satellite images.
In the most recent sign of growing frustration between Washington and Pyongyang, North Korea criticised senior American officials for insisting that North Korea give up its nuclear weapons first before easing sanctions.
North Korea called out the U.S.' "shameless and impertinent behavior", according to a press release out Thursday via a foreign ministry spokesperson.
They said it had also not agreed to definitions of the key terms of any agreement, or to any inspection of its nuclear test site, which it claims to have decommissioned, but which US intelligence officials have said may still be operable. They said that when a session with Pompeo reached an impasse last month, North Korean officials asked if he would like to step outside to call the president, who declared after the June summit that North Korea was "no longer a nuclear threat".
"They made public the North Korea Sanctions and Enforcement Actions Advisory; and additional sanctions".
