SEOUL — North Korea appeared unwilling on Sunday to respond harshly after President Trump reversed course to declare the country still a threat, with Kim Jong Un's regime pledging that it seeks a “new era” with the United States but offering no specific plans toward dismantling its nuclear program.

The comments also did not address promises by North Korea to return the remains of some unaccounted-for U.S. military personnel from the Korean War. On Saturday, the U.S. military sent 100 wooden coffins to a U.N.-supervised area in the demilitarized zone separating the two Koreas in anticipation of receiving some of the remains.

A report in Uriminzokkiri, a North Korean website that reflects the views of Kim's regime, urged both sides to move ahead with “faithfully implementing” the joint declaration from the June 12 summit in Singapore between Trump and Kim.

The document expressed Kim’s “firm and unwavering commitment to complete denuclearization of the Korean Peninsula.”

But North Korea has yet to clarify its interpretation of denuclearization in the region. In the past, Pyongyang has defined it to include an end to the U.S.-South Korea military alliance and U.S. withdrawal of its nuclear umbrella protecting South Korea and Japan.

“We will conscientiously fulfill our responsibility to address decades-long tensions and hostile relations, and open a new era of the North-U.S. cooperation,” the Uriminzokkiri report added, without mentioning North Korea’s nuclear program or Trump.

Trump on Friday cited the “unusual and extraordinary threat” posed by Kim’s regime as he renewed U.S. economic sanctions on North Korea. Trump’s notice to Congress was in sharp contrast to his post-summit assertions that North Korea was no longer a nuclear threat to the United States.

In an apparent confidence-building step, the Pentagon and South Korea’s military have suspended military exercises. After the summit, Trump called the long-standing military drills “provocative, expensive and inappropriate,” echoing language used by North Korea.

“The path to thoroughly implementing the North-U.S. joint statement is the path to securing the common interests of the peoples of the two countries, and peace, security and prosperity on the Korean Peninsula and in the world,” the Uriminzokkiri report said.

According to the Defense POW/MIA Accounting Agency, 7,700 American service members who fought in the Korean War remain unaccounted for, and the remains of about 5,300 are believed to be located within North Korea. North Korean officials have said that they have recovered the remains of about 200 U.S. service members since the active conflict with the United States ended.

Repatriation of remains has occurred in the past, but only sporadically.
