Congress on Monday said it was "very happy" over the progress made in the IAEA talks in connection with the Indo-US nuclear deal and sought to bring the Left around for an understanding over the ticklish issue.
"We are happy that India has made significant and notable progress at the IAEA talks. We are particularly happy that a vast and diverse area of differences have been covered, have been ironed out in the fifth round of talks," AICC spokesman Abhishek Singhvi told reporters.
Singhvi made a suo-motu statement at the AICC briefing saying it was "equally optimistic, positive and hopeful" about the deliberations and consultations at the Joint Mechanism of the UPA and Left parties which shall follow after the IAEA talks.
"We are confident of a constructive approach by all concerned... Totally confident and sure of a reasonable approach by all sections of the Joint Mechanism", he said.
The AICC spokesman's statement came on a day when External Affairs Minister Pranab Mukherjee made a statement in Parliament on foreign policy issues including the nuclear issue.
Questioning certain statements from the US, Mukherjee made it clear that its rights and obligations on civil nuclear cooperation came only from the bilateral 123 Agreement and the controversial Hyde Act did not bind it.
