North Korea said Monday it is willing to resume nuclear diplomacy with the United States in late September, but that Washington must come to the negotiating table with acceptable new proposals.

If the proposals don’t satisfy North Korea, dealings between the two countries may come to an end, First Vice Foreign Minister Choe Son Hui said.

Choe’s statement was apparently aimed at pressuring the United States to make concessions when the North Korea-U.S. talks restart.

North Korea is widely believed to want the United States to provide it with security guarantees and extensive relief from U.S.-led sanctions in return for limited denuclearization steps.

There was no immediate U.S. response. But U.S. officials have recently said they are ready to restart talks with North Korea.

In the late-night statement carried by state media, Choe said North Korea is willing to sit down with the United States “for comprehensive discussions in late September of the issues we have so far taken up, at a time and place to be agreed.”

Choe said she hopes the United States will bring “a proposal geared to the interests of the DPRK and the U.S. and based on decision methods acceptable to us.” DPRK stands for the Democratic People’s Republic of Korea, the North’s official name.

She warned that “If the U.S. side fingers again the worn-out scenario which has nothing to do with new decision methods at the DPRK-U.S. working negotiation to be held with so much effort, the DPRK-U.S. dealings may come to an end.”

Talks on North Korea’s nuclear disarmament fell apart in February when President Donald Trump rejected North Korean leader Kim Jong Un’s demand for sweeping sanctions relief in return for partial disarmament at their second summit in Vietnam.

It was a huge embarrassment for the young North Korean leader, who made a dayslong train trip to the Vietnamese capital to obtain the sanctions relief he needs to revitalize his country’s troubled economy.

In April, Kim said he was open to another summit with Trump, but set the end of the year as a deadline for the U.S. to offer improved terms for an agreement to revive the nuclear diplomacy. Kim and Trump met again at the Korean border in late June and agreed to restart diplomacy, but there have no public meetings between the sides since then.

In recent months, North Korea has carried out a slew of missile and rocket tests to protest joint military drills between the U.S. and South Korea that North Korea views as an invasion rehearsal. Some experts said the North Korean weapons tests were also a demonstration of its expanding weapons arsenal aimed at boosting its leverage ahead of new talks with the United States.

Most of the North Korean weapons tested in July and August have been short range. This suggests that North Korea hasn’t wanted to lift its self-imposed moratorium on nuclear and long-range missile tests, which would certainly derail negotiations with Washington.

Trump has downplayed the latest North Korean weapons tests, saying the U.S. never restricted short-range tests.
