Foreign Minister Hirofumi Nakasone may ask China to reduce its nuclear arsenal, government sources said.
Nakasone may make the request in an address on nuclear disarmament he will give on April 27 in Tokyo at the Japan Institute of International Affairs.
Prime Minister Taro Aso may also touch on the request when he meets with Chinese President Hu Jintao and other Chinese leaders during his April 29-30 visit to China, the sources said Wednesday.
