Foreign Minister Fumio Kishida called on the international community Tuesday to strengthen the nuclear nonproliferation regime, citing the growing threat posed by North Korea's nuclear and missile programs.

Taking part in the preparatory committee for the 2020 review conference of the Nuclear Non-Proliferation Treaty in Vienna, the first Japanese foreign minister to do so, Kishida also urged cooperation between nuclear states and non-nuclear states to prevent the spread of nuclear arms.

"North Korea has conducted two nuclear tests and launched more than 30 ballistic missiles since last year. Its nuclear and missile development has reached a new level and is posing a real threat to the region and beyond in the international community," Kishida told the committee.
