==The State Department is responsible for negotiating 123 agreements, with technical assistance and the DOE/NNSA agreement and in agreement with the U.S. Nuclear Regulatory Commission. Japan had more than 47 tons of plutonium in 2016, enough to produce about 6,000 nuclear warheads. Ten tons of this material are stored in Japan, the rest being stored in France and the United Kingdom. Critics fear that these materials could be used to build nuclear weapons, allowing Japan to acquire latent nuclear weapons. The Nikkei Asian Review reported that before extending the pact, the United States was asking Japan to make efforts to reduce inventories. On 31 July, Japan`s Nuclear Energy Commission adopted a directive to limit plutonium production and, finally, reduce stockpiles, but it did not give a timetable or details on a plan to that effect. .
