SEOUL--North Korea said Tuesday it won’t consider a recent U.S. decision to postpone a joint military exercise with South Korea a major concession that can bring it back to nuclear talks.

Senior North Korean official Kim Yong Chol said the United States must completely scrap that military drill and abandon its hostility against his country if it wants to see the resumption of the nuclear negotiations.

Kim’s comments were the first direct response to an announcement Sunday by U.S. Defense Secretary Mark Esper and his South Korean counterpart that the allies have indefinitely postponed the annual Vigilant Ace training in an “act of goodwill” toward North Korea. The moves were regarded as an effort to convince North Korea to revive the nuclear talks that largely have stalled since the February collapse of a summit between U.S. President Donald Trump and North Korean leader Kim Jong Un.

“The U.S. tries to make a good impression as if it contributes to peace and stability on the Korean Peninsula, describing the suspension (of the aerial drill) as ‘consideration for and concession’ to someone,” Kim Yong Chol said in a statement carried by state media. “But we demand that the U.S. quit the drill or stop it once and for all.”

North Korea wants the United States to lift international sanctions on it, provide security guarantees and make other concessions in return for abandoning its advancing nuclear arsenal. The February summit in Vietnam, the second such meeting between Trump and Kim Jong Un, fell apart after Trump rejected Kim’s demand for sweeping sanctions relief in exchange of dismantling his main complex to produce nuclear ingredients, a limited disarmament step.

The two leaders held an impromptu, brief meeting at the Korean border in late June and agreed to restart diplomacy. In early October, their nuclear negotiators eventually resumed talks in Sweden, but the meeting failed to report progress.

North Korea said last week the United States recently proposed via an unidentified third country its offer to meet again in December. North Korea still said differences between the two countries won’t be addressed with minor concessions like establishing a liaison office between the countries or formally declaring the end of the 1950-53 Korean War.

Kim Myong Gil, roving ambassador at the North’s Foreign Ministry, disclosed Tuesday it was Sweden which conveyed the U.S. dialogue proposal. He said North Korea wants the United States not to go through a third country to offer talks and Sweden not to try to mediate in North Korea-U.S. diplomacy.

“It is not for lack of communication channel or mediator that (North Korea)-U.S. negotiations have not yet been held,” Kim said. “The Swedish side would be well-advised to properly understand the situation and behave itself.”

After the announcement on the drill’s postponement, Trump in a tweet urged Kim Jong Un “act quickly, get the deal done,” saying “See you soon!”

But senior North Korean Foreign Ministry adviser Kim Kye Gwan said Monday his country has no interest in giving Trump further meetings to brag about unless it gets something substantial in return.

In his Tuesday statement, Kim Yong Chol also accused the United States of trying to buy time as a North Korea-set deadline for Washington to work out new proposals by year’s end is approaching.

“The U.S. should not dream of the negotiations for denuclearization before dropping its hostile policy toward” North Korea, he said.

Kim Yong Chol is one of Kim Jong Un’s close associates who led nuclear diplomacy with the United States and traveled to Washington twice before the failed February summit.
