Japan on Monday urged Iran to follow its commitments under a 2015 nuclear agreement with major powers and refrain from taking further actions to undermine it, after Tehran said it had started enriching uranium above the limit set by the deal.
"We are deeply concerned about Iran's announcement" on Sunday, Deputy Chief Cabinet Secretary Yasutoshi Nishimura said at a news conference. "We strongly urge Iran to abide by the nuclear agreement, immediately return to its commitments and refrain from taking steps that would damage the accord."
Japan, which has built amicable ties with Iran, has supported the nuclear deal as a way to promote stability in the Middle East.
