The NSG meeting, to be attended by the US and other countries of the 45-member group, is likely to hold preliminary discussions on change in guidelines to allow international nuclear trade with India.
Facing questions from Indian reporters, Kakodkar emphasised that it was the US responsibility to get NSG exemption for India.
India has to reach a safeguards agreement with the International Atomic Energy Agency (IAEA) soon and secure changes in NSG laws to operationalise the deal, he said.
Kakodkar, who is attending the IAEA General Conference, underpinned the importance for expeditiously operationalising the deal. "It is in everybody's interest to conclude the nuclear deal sooner than later.
"Everyone in the nuclear community wants early negotiations between India and IAEA as also the NSG to implement the deal," he said.
The top nuclear scientist, however, made no direct mention on whether he will discuss the India-specific safeguards agreements with the IAEA during his current visit. "My lips are sealed on anything to do with the India-specific safeguards."
