The revised text of the draft India waiver to be considered at next week's NSG meeting is ready with some changes being incorporated in it, sources said in New Delhi on Thursday.

The Indian side is expected to examine the draft in a day or two to give its clearance for its introduction at the September 4-5 meeting of the Nuclear Suppliers Group depending on whether its objective of "unconditional" exemption is ensured.

In the draft, the US is believed to have attempted to strike a balance between addressing the concerns of the sceptic nations and ensuring that it is free of conditionalities.

Though India has held preliminary discussions with the US over revision of the draft, it will be keen to see that the revised document does not contain any language or elements that would bind it in lieu of the waiver.

Foreign Secretary Shivshankar Menon, who is in Washington, has held discussions with US Under Secretary of State William Burns on the draft soon after several NSG members at the August 21-22 meeting sought changes in it to address their non-proliferation concerns.

India has been insisting on an "unconditional" waiver and made it clear that it would walk away if the waiver was found to bind it.

Around 15 countries particularly New Zealand, Austria, Switzerland and Norway have voiced apprehensions over grant of waiver to India since it has strategic nuclear programme despite which it is not a signatory to the NPT.

At the last NSG meeting in Vienna, the sceptic countries suggested at least 50 amendments to the draft to make it acceptable to them.

To ensure smooth sailing at the September 4-5 meeting of the NSG, the US is continuing lobbying efforts to convince the apprehensive countries about the initiative for India.

As part of these efforts, US Ambassador David Mulford has been meeting envoys of New Zealand, Switzerland, The Netherlands, Norway and Austria which have reservation to grant of exemption.
