Criticism and disappointment have been sharp in Japan and internationally after delegates to the review conference on the Treaty on the Non-Proliferation of Nuclear Weapons failed to issue a final document.

A survivor of the 1945 atomic bomb attack on the western Japanese city of Hiroshima expressed frustration.

Mimaki Toshiyuki said, "I just beg that nuclear weapons be abolished while I'm still alive. I would honestly like this to happen very soon, but it's hard to see."

Friday's closing session of the NPT review was the culmination of four weeks of talks. Russia was the only state to object to the wording of a draft statement.

It referred to the Russia-controlled Zaporizhzhia nuclear power plant in southeastern Ukraine. The document noted that the parties agreed the plant should be controlled by Ukrainian authorities. It did not mention Russia by name.

After Russia objected to such wording, the Ukrainian delegate said, "Unfortunately, Russia has confirmed its unwillingness to adhere to the NPT regime. The deliberations in the room have also clearly demonstrated how isolated the delegation of the Russian Federation is."

The US delegate said, "The last minute changes Russia sought were not of minor character. They were intended to shield Russia's obvious intent to wipe Ukraine off the map."

Japanese Prime Minister Kishida Fumio said the conference outcome was extremely regrettable.

He had addressed the UN meeting at its outset earlier this month, laying out his proposal to realize a world free of nuclear arms.

Kishida said, "With the belief that maintaining and strengthening the NPT is the only realistic path toward nuclear disarmament, we will proceed with our efforts with a historical sense of mission, as the only country to have suffered from attacks by atomic bombs."

A member of the International Campaign to Abolish Nuclear Weapons criticized the stance of the nuclear powers.

Kawasaki Akira said, "I think it's necessary to create an upsurge in international public opinion that will encircle the nuclear powers in such a way that there won't be a situation where the nuclear powers have veto power."

There was also criticism and disappointment in Nagasaki, the second city to have been attacked with an atomic bomb.
