North Korea’s foreign minister on Wednesday said his country is not even considering a resumption of stalled nuclear talks with the United States, dismissing hopes expressed by U.S. and South Korean officials for a quick resumption of negotiations.

The statement by Ri Son Gwon came a day after the powerful sister of North Korean leader Kim Jong Un issued a message saying that U.S. expectations of talks would “plunge them into a greater disappointment.”

Hope for a restart of the nuclear talks flared briefly after Kim Jong Un instructed officials at a political conference last week to prepare for both dialogue and confrontation — though more for confrontation — with the Biden administration. U.S. National Security adviser Jake Sullivan called Kim’s comments an “interesting signal.”

Ri praised the statement issued by Kim’s sister, Kim Yo Jong, which he said brushed off the “hasty judgment, conjecture and expectation of the U.S.”
