In the midst of the tense negotiations at Vienna where China created problems in the waiver in the Nuclear Suppliers Group (NSG), India had conveyed its unhappiness to Beijing through a demarche.
Informed sources said that India made known its disappointment to China which had joined hold-out countries -- Austria, New Zealand, Ireland and Switzerland -- who wanted their concerns to be reflected in the waiver.
India got the waiver after a consensus among NSG members at the end of five rounds of negotiations and a statement by External Affairs Minister Pranab Mukherjee re-affirming India's strong commitment to non-proliferation goals.
Mukherjee had also assured the global community that India remained committed to a voluntary, unilateral moratorium on nuclear testing.
