Australian Foreign Minister Kevin Rudd on Thursday rebuffed his Indian counterpart's latest plea for Australian uranium.

Indian Foreign Minister SM Krishna touched down in Australia on Wednesday to meet Rudd for the seventh annual Foreign Ministers Framework Dialogue, which held in Melbourne on Thursday.

Earlier, Labor government refused to sell uranium to India, because the country has not signed the United Nations Nuclear Non-Proliferation Treaty.

Krishna is using his visit to lobby the government to lift its ban on selling uranium to India, saying that India's moves towards clean energy could only be achieved with nuclear power.

Rudd said India, Australia's fifth-largest trading partner, is a commercially important partner and the two democracies share "many fundamental commonalties".

However, Rudd made it clear the government had no plans to relax the policy on uranium.

The comments echoed Resources Minister Martin Ferguson, who met Krishna on Wednesday.

Australian Greens spokesman for nuclear issues Scott Ludlam welcomed the government's resolve.

"Resources Minister Martin Ferguson and Foreign Minister Kevin Rudd should be congratulated for putting Australia's international security obligations ahead of the interests of uranium mining companies," he told Australia Associated Press on Thursday.

Meanwhile, Rudd and Krishna on Thursday also discussed moves towards a new Asia-Pacific regional architecture, piracy, people smuggling and the welfare of Indian students in Australia.

Krishna last visited Australia in 2009 for emergency talks on a series of much-publicized attacks on Indian students in Victoria of Australia. The attacks were a major contributor to a subsequent drop in Indian student numbers.
