An international forum launched by Japanese Prime Minister Kishida Fumio has held two days of talks on nuclear disarmament in the atomic-bombed city of Hiroshima.

Delegates from both nuclear powers and non-nuclear states took part in the first meeting of the International Group of Eminent Persons for a World without Nuclear Weapons.

The delegates visited the Peace Memorial Museum on Sunday.

Kishida attended the closing session and called on the participants to try to bring about a world without nuclear weapons.

He said Japan hopes to deepen discussions to send a strong message toward a world without nuclear weapons at next year's Group of Seven summit in Hiroshima.

The forum was chaired by Shiraishi Takashi, an expert in international politics. He said various issues were discussed at the meeting, including the reasons why nuclear disarmament hasn't gained momentum.

Denuclearization initiatives have stalled recently. Delegates at the nuclear non-proliferation treaty review conference in August failed to reach a broad consensus or adopt a joint document.
