Prospects for dialogue between the Democratic People's Republic of Korea (DPRK) and the United States are increasingly narrowing, DPRK's Foreign Ministry warned on Tuesday. 

The U.S. State Department found fault with the DPRK in the "2018 Country Reports on Terrorism" released on Friday, said a spokesperson for the foreign ministry in a statement published in the official Korean Central News Agency. 

The United States has persistently tried to brand the DPRK as a "state sponsor of terrorism" at a sensitive time when the DPRK-U.S. dialogue is at a stalemate. This is an insult to and perfidy against the DPRK, the spokesperson said. 

"The channel of the dialogue between the DPRK and the United States is more and more narrowing due to such attitude and stand of the United States," it said.

It also said the foreign ministry condemns and fully rejects the reports as a grave politically-motivated provocation against the DPRK as they are full of all sorts of falsehoods and fabrication. 

It is the DPRK's consistent stand to oppose all forms of terrorism and any support of it, it added. 

The working-level negotiations between the DPRK and the U.S. in Stockholm ended in a stalemate in early October.  

Seoul's spy agency, the National Intelligence Service, said on Monday that the DPRK and the U.S. are expected to hold another round of working-level nuclear talks no later than early December, according to Yonhap news agency.
