Describing the increasing Indo-US military cooperation as "positive", a top Pentagon official said the growing defence links reflects the continuing and emerging relationship between the two nations.

"I think there's a very positive and growing relationship between the two countries. And I think that's a very good thing," Chairman of the Joint Chiefs of Staffs Admiral Mike Mullen said.

"India is providing not just for its own people a growing economic engine which, again, I think is good not just locally, but also globally," he said at the Washington Foreign Press Centre.

Mullen noted that recent years have witnessed an increase in military-to-military contacts between the US and India.

"And I think that's positive. So I'm actually very positive about the continuing and emerging relationship between the United States and India," Admiral Mullen said.
