WASHINGTON — North Korean state media criticized the United States over the weekend for “extremely provocative and dangerous military moves” in Pacific waters and warned that the diplomacy forged between the two countries’ leaders during their Singapore summit meeting in June could be in jeopardy.
The belligerent articles were the first official comments from North Korea since a frustrated President Trump announced on Friday that Secretary of State Mike Pompeo was canceling his most recent plan to travel to Pyongyang, the North Korean capital.
Mr. Trump’s announcement, made in a series of tweets, was the first acknowledgment by the American president that the diplomatic process with North Korea had stalled.
He said the United States had not been making “sufficient progress” on getting North Korea to halt or dismantle its nuclear weapons program, and blamed China for the slow progress. Some American officials and analysts in Beijing, however, have said China generally has adhered to an American-led economic sanctions plan against North Korea.
On Sunday, the Korean Central News Agency, the official state news agency of the government in Pyongyang, reported that American “special units” had flown 1,200 kilometers, or about 745 miles, to the Philippines over Pacific waters. It described the exercise as preparing for an “infiltration into Pyongyang,” which could be done with a “change of direction.”
The report also said the U.S.S. Michigan, a nuclear-powered ballistic missile submarine, had transported units of Green Berets, Delta Force and other elite soldiers in late July or early August from Okinawa, Japan, to a naval base in South Korea.
The news agency cited South Korean radio as its source, not any independent evidence. The Pentagon generally does not comment on operations of its special units.
In a statement on Monday, the State Department said Mr. Pompeo spoke last week with the South Korean foreign minister, Kang Kyung-wha, and the two men “agreed that pressure must continue” until Pyongyang dismantles its nuclear weapons program. Mr. Pompeo also appointed a special envoy, Stephen E. Biegun, last week to oversee diplomacy with North Korea.
At his June meeting in Singapore with the North Korean leader, Kim Jong-un, Mr. Trump promised to cancel military exercises between the United States and South Korea, which surprised both the Pentagon and the South Korean government. Since then, large exercises between the two allied nations have been put on hold. The United States maintains about 28,500 troops in South Korea.
The Pyongyang news report did not provide details on the American military moves that North Korea was asserting had taken place. It appeared to lay the foundation for blaming stalled diplomacy on American officials by accusing them of reneging on promises made at the summit meeting.
The news agency cited a Sunday commentary in Rodong Sinmun, the official newspaper of the central committee of the Workers’ Party of Korea, that said the “extremely provocative and dangerous military moves” would “mar the hard-won atmosphere of the peace on the Korean Peninsula” and the dialogue and agreements that had come out of the summit meeting.
The commentary said that “such acts prove that the U.S. is hatching a criminal plot to unleash a war” against North Korea and “commit a crime which deserves merciless divine punishment.” It also said the United States had “double-dealing attitudes” and was trying to engage in diplomacy with “a smile on its face” while conducting military drills with special units.
Right after the summit meeting, Mr. Trump said that North Korea was on the path to “denuclearization” and that the nuclear threat had abated. In fact, North Korea never promised to get rid of its nuclear weapons, and experts estimate that it has as many as 60 warheads. It also has been developing a ballistic missile that can deliver a warhead to the mainland United States.
North Korean officials want the United States to first support a peace declaration that will bring a formal end to the Korean War, which began in 1950. The South Korean government has also said this should be a priority.
“Perhaps we’re starting to see the frustration in the White House over being played on these grandiose promises of denuclearization that the North Koreans do not intend to fulfill until they get everything they need, and want, from the United States in return,” said Jean H. Lee, director of the Wilson Center’s center on Korean history and public policy.
