In a sign of Pyongyang's growing impatience with stalled nuclear talks with Washington, North Korea has warned the United States that its stance on crippling sanctions could "block the path to denuclearization on the Korean Peninsula forever."

In a statement published Sunday by the North's official Korean Central News Agency, the country's Foreign Ministry heaped praise on U.S. President Donald Trump but delivered a stinging critique of the State Department, which it said is "bent on bringing the DPRK-U.S. relations back to the status of last year which was marked by exchanges of fire."

DPRK is the acronym for the North's formal name, the Democratic People's Republic of Korea.
