"More than just six states are opposed to a 'Clean' or 'Unconditional' waiver. It has been widely reported that a group of six like-minded states (Austria, Ireland, New Zealand, Netherlands, Norway, and Switzerland) have put forward proposals for restrictions, conditions, and a review mechanism for nuclear trade with India, but the group of states backing these ideas is actually far larger, probably around 15 total," Kimball maintained.

"These include Japan, several other northern European states, and possibly China. The commentary yesterday in China's official People's Daily calls the India deal a "major blow" to non-proliferation, raising possibility that China is unhappy with the proposed US waiver for India," he added.
