Full-fledged reinforcement of the international nuclear nonproliferation framework is of vital importance for facilitating peaceful use of nuclear power and thereby for addressing the pressing global challenges of energy supply and global warming, according to a private policy study group.

To attain this goal, all nations, regardless of whether they have nuclear capability, must work on nonproliferation initiatives, such as stepped-up disarmament efforts and reinforcement of nuclear site inspections, according to the Study Group on Nuclear Nonproliferation.

The proposal by the 12-member expert group, headed by Shunji Yanai, former ambassador to the U.S., was submitted to Chief Cabinet Secretary Nobutaka Machimura last Wednesday.
