A special meeting of the Nuclear Suppliers Group is expected to be held on Thursday to discuss India's demand for a "clean, unconditional" exemption in order to implement the Indo-US nuke agreement.

Ahead of the meeting, Atomic Energy Commission chief Anil Kakodkar said India, not being a signatory to the nuclear Non- Proliferation Treaty, expects the United States to work out clean and unconditional exemption from Nuclear Supply Group for India.

It is expected that the NSG will hold a meeting in this regard at the Japanese centre here. However, India has to wait for such a demanding waiver from NSG.
