Australia's largest uranium producer has welcomed the possibility of being able to sell uranium to Russia.

The Federal Government is looking at ratifying a treaty which will enable the sale of uranium to Russia.

Energy Resources of Australia operates the Ranger uranium mine inside Kakadu National Park in the Northern Territory.

The general manager of external relations, David Paterson, says the company has no plans at this stage to sell to Russia.

"Not in the short term, I think that those decisions about bi-lateral agreements between Australia and other countries are really matters for the Australian Government," he said.

"We've got a really strong portfolio of customers around the world but it's certainly welcome news to see additional markets opening up."
