The leaders of the Group of Seven nations are set to issue a statement criticizing Russia for posing a nuclear threat and expressing concerns about China's efforts to increase its nuclear weapons capabilities.
NHK obtained a draft of the statement focusing on nuclear disarmament separate from the members' statement.
At the beginning of the draft, the leaders gathered in Hiroshima reconfirm their commitment to realizing a nuclear-free world. It says the Japanese city evokes memories of unprecedented destruction and inhuman suffering.
The draft stresses the importance of the non-use of nuclear weapons since 1945, and calls Russia's nuclear threat irresponsible, dangerous and unacceptable.
The draft also expresses concerns about China's efforts to increase its nuclear weapons capabilities. It cites a need to secure transparency, and calls on nuclear powers not publishing objective data of these capabilities to disclose such information.
The draft says the members are determined to maintain the framework of the Treaty on the Non-Proliferation of Nuclear Weapons. They also welcome Japan's Hiroshima Action Plan for a nuclear weapon-free world, unveiled by Prime Minister Kishida Fumio.
The draft calls for having the Comprehensive Nuclear-Test-Ban Treaty promptly enter into force.
It also calls on other world leaders and young people around the globe to visit Hiroshima and Nagasaki.
The Japanese government is to finalize the statement after a meeting of the members on Friday night.
