China's Foreign Ministry has issued another statement, once-again calling on Japan to respond to the international community's concerns over its nuclear material stockpiles as soon as possible.
Chinese Foreign Ministry spokesperson Qin Gang.
"Avoiding answering questions does not help solve the problem and China is urging Japan to face up to these issues and hopes that Japan can give explanations as soon as possible. Japan should take measures to cope with doubts and concerns expressed by the international community."
The statement comes despite assurances by the head of the International Atomic Energy Agency that Japan's stockpile of nuclear materials is under full IAEA observation.
The United States has begun pressing Japan, once again, for the return of some 331-kilograms of weapons-grade plutonium it gave to Japan during the Cold War.
The US side began calling for the return of the nuclear materials in 2010.
Japan is officially a nuclear weapons-free country.
