North Korea’s leader Kim Jong-un announced that his country is renouncing the moratorium placed on its nuclear and long-range missile tests. The moratorium had been put into effect during the talks with the United States.

Despite this reversal, Kim pledged that he was still open to further discussions with the U.S.

During his speech, he also said that North Korea is pursuing further developments and most notably will seek to introduce a “new strategic weapon” in the near future, though he did not offer any additional information.

The announcement came after a four-day meeting of officials of the Workers’ Party of Korea, which governs the country. Kim had previously called for the United States to offer further concessions before any further progress; the U.S. government had refused.
