Japan's foreign minister has expressed hope for reaching a nuclear deal between the United States and North Korea before the 2020 US presidential election.
Taro Kono was speaking to reporters on Friday ahead of the planned second summit between US President Donald Trump and North Korean leader Kim Jong Un next week in Vietnam.
Kono noted that the US has a presidential race every four years, and that the presidential term is four years.
He said he understands that scrapping all of North Korea's nuclear weapons and missiles will take time.
He stressed that a certain decision to that end should be made while Trump is in office.
Kono also commented on South Korea's proposal to reestablish railway links between the two Koreas as part of inter-Korean economic cooperation to help implement denuclearization. He said he understands that any economic cooperation should come after sanctions against the North are lifted.
He also said reopening the Kaesong industrial complex and the Mount Kumgang resort in the North, whose operations were suspended as part of the sanctions, should not be allowed.
