SEOUL, South Korea — North Korea acknowledged for the first time on Friday that the summit meeting last week between its leader, Kim Jong-un, and President Trump ended without an agreement, claiming that people “in and outside” the North were blaming the United States for the breakdown.

Until now, North Korea’s state news media had not reported the collapse of the summit meeting, held in Hanoi, Vietnam, on Feb. 27 and 28. The failed summit was considered a big embarrassment for Mr. Kim because he had to return home empty-handed after Mr. Trump rejected his demand for relief from United Nations sanctions.

“People in and outside the North had hoped that the second North Korea-United States summit meeting, held in Hanoi, would yield good results,” the Rodong Sinmun, the newspaper published by the North’s ruling Workers’ Party, said in a commentary on Friday. “After it unexpectedly ended without an agreement, they are letting out sighs of regret, all arguing that the United States was responsible.”

But the commentary also said that “the whole world sincerely hopes that the peace process on the Korean Peninsula will proceed smoothly and the North Korea-United States relations will improve soon.”
