An Australian-driven commission aimed at promoting global debate about nuclear disarmament and non-proliferation has wrapped up a three-day meeting in Moscow.

The Russian and American presidents are due to hold their own talks on nuclear weapons cuts next month.

The International Commission on Nuclear Non-proliferation and Disarmament has used its Moscow get-together to meet senior Russian government officials.

Anti-nuclear campaigners have also addressed the meeting. They argue that with the US and Russia talking about reducing their nuclear arsenals, now is the time to intensify the push for a comprehensive treaty to abolish nuclear weapons.

Commission co-chair Gareth Evans says that is the ultimate goal but it will take a lot of time.

"Nobody's coming to that party for the foreseeable future; it is going to have to be a step-by-step approach," he said.

The Commission has also held talks in Moscow with representatives of the world's nuclear power industry.
