New Delhi, Jan 30 (PTI) Australia will embark on commercial discussions with India on the nuclear commerce, a senior Australian High Commission officer said here today but did not give any time frame for it. Terming as "positive" the proposed move of 46th national conference of the ruling Labour Party to export uranium to India, a resolution for which was moved by Prime Minister Julia Gillard, Counsellor-Commercial in the High Commission Grayson Perry, said "robust discussions (political and commercial) will take place between India and Australia. "It is a positive move because earlier there were no discussions", he said. Last month, the Labour voted to overturn a decades-old ban on uranium sale to India, paving the way for Canberra to supply it to a nation outside the Nuclear Non-Proliferation Treaty. "We are going to embark on it (commercial discussions)," he said. However, he did not give a time frame for this. Australia has almost 40 per cent of the worlds known uranium reserves but has not been supplying it to non-NPT signatories. India has been requesting Canberra for long to overturn it ban on exporting uranium to it.
