He was speaking to reporters onboard USS Blue Ridge which is anchored at Mormugao Port Trust (MPT). Carter and Defence Minister Manohar Parrikar paid visit to the ship which arrived here from Mumbai.
Indo-US defence ties were going to be "defining relationship of 21st century", he said.
"That is because both our values and our interests overlap in important way and that happens with few countries around the globe and India is one of those which is influential and very important country," he said, adding that America is pleased to have partnership with India.
Carter, who is scheduled to hold a meeting in New Delhi tomorrow, said discussions would be held on Defence Technology and Trade Initiative (DTTI).
"Agreement is very important. We can do a lot with agreement. Stay tuned for tomorrow," he said.
On supplying predator drones to India to spy on Pakistan, Carters said "Generally the US policy and approach to India is about India and its role in the region and it is not about particular neighbour. We have a relationship with India which reflects today's American way of thinking".
To a question, he said US respected India's independence (in policy matters).
"Their (India's) policy is that of supplier of security in the region which is compatible with our policy. It is inclusive one and not exclusive one," he said.
