China had better lighten up on the sabre rattling:
According to the AP, "Japan now has 45.5 tons of separated plutonium — 8.9 tons at home, and 36.6 tons in Britain and France, where spent fuel from Japanese nuclear plants has been reprocessed and stored because Japan lacks a plant to produce MOX [mixed-oxide] fuel containing plutonium at home. The amount is enough to make about 6,000 atomic bombs."
