North Korea said on Thursday it had turned down a U.S. offer for fresh talks, saying it was not interested in more talks merely aimed at “appeasing us” ahead of a year-end deadline Pyongyang has set for Washington to show more flexibility in the negotiations, reports Reuters.

Kim Myong Gil, the North’s nuclear negotiator, said in a report carried by state media that Stephen Biegun, his U.S. counterpart who jointly led last month’s failed denuclearization talks in Stockholm, had offered through a third country to meet again.

Kim and Biegun met last month in the Swedish capital for the first time since U.S. President Donald Trump and North Korean leader Kim Jong Un agreed in June to re-open negotiations that have been stalled since a failed summit in Vietnam in February. But the Stockholm meeting fell apart, with Kim Myong Gil saying the U.S. side had failed to present a new approach.
