A deal could include partial sanctions relief and a freeze (2019). Washington rumor now has it that the Trump administration is considering offering North Korea some temporary sanctions relief for a freeze of its production of nuclear warheads and missiles. The mooted deal would also include the shutdown of North Korea’s best-known nuclear reactor, at Yongbyon. It does not, however, indicate what range missiles would be frozen. The latter matters to regional allies, especially Japan, which is threatened by shorter range missiles than North Korea would use to strike the United States mainland.
