The Federal Government says it will consider Russia's aggression in Georgia before it ratifies a deal to sell uranium to Russia.

Russia's ambassador to Australia, Alexander Blokhin, has reportedly warned any scrapping of the deal would be "politically biased" and economically harmful.

"We do not see any connection between the events in the Caucasus region and the uranium deal," Mr Blokhin was quoted as saying.

"These are completely separate things. The agreement on uranium is actually an agreement about the use of atomic energy only for peaceful civilian aims.

"If this agreement is not ratified, in that case we could regard that as an obversely political biased decision, which could harm the economic interests of Australia as well."

Foreign Minister Stephen Smith has said the Government believes the agreement promotes the highest international standards in nuclear safeguards and meets Australia's requirements.

The Special Minister of State, John Faulkner, says Mr Smith will not be responding to the ambassador's latest statements.

"Mr Smith has made clear in relation to the comments made by the Russian ambassador that he did not intend to get into a public debate with the Russian ambassador," he said.

'A case for delay'

Senator Faulkner says the previous Coalition government signed the new bilateral agreement to sell uranium to Russia, because it was confident that the deal was consistent with nuclear safeguards.

He says the Labor Government has taken a different path.

"The approach of the Rudd Government on coming to office was to table the agreement in Parliament in May of this year and of course the Government has submitted the agreement to the Parliamentary joint standing committee on treaties for examination," he said.

But members of Federal Parliament's Treaties Committee have raised concerns about the deal.

Committee chairman Kelvin Thomson says there might be reasons to delay the agreement, as there has not been an inspection by the international atomic energy agency in Russia since 2001.

Mr Thomson says Russia has signed treaties in the past, then failed to abide by the obligations.

"I think that if you look at some of those things it suggests that there might be a case for delay in relation to this treaty," he said.

"Now the treaties committee hasn't considered the matter yet and I certainly don't want to pre-empt any of my colleagues; we need to have a discussion about these issues."

The Greens have urged the Federal Government to abandon the negotiations.

Greens Senator Christine Milne says if the agreement goes ahead, Russia could sell Australian uranium to Iran.

She says it is time for the Government to put a stop to negotiations.

"If they can't see that [Russian President] Vladimir Putin is a formidable opponent, that he is going back to the old KGB days, then they are blind in terms of foreign policy and just looking at the uranium sales," he said.
