Canberra: India on Monday said its commitment to nonproliferation is "second to none' and the issue of procuring uranium from Australia will come up once it firms up an international arrangement for nuclear commerce. External affairs minister Pranab Mukherjee, who met his Australian counterpart Stephen Smith here, also said it was "too early' to refer to the issue of uranium sale as political discussions back home on implementing the Indo-US nuclear deal were still on. "I have not come here with one issue of getting uranium from Australia. We are aware of the Labour party position on uranium for quite some time. Australia's commitment to non-proliferation is firm and we respect that,' he said at a joint press conference after the meeting. "So far our requirement of uranium is concerned I think it's too early to refer to that as it has been pointed out by Smith...I am really busy back home in political front in regard to implementing 123 Agreement with the US. It is an exercise to catch a trend which has no possibility or when it will arrive at the platform we don't know.' PTI
