Alice D Ba, who is here as part of US state department's public policy programme, said India's influence culturally and in terms of population was quite strong.
"I think as a diplomatic presence, it is not as prominent as one might expect given those other influences. Economically it could probably be stronger," she said.
An associate professor of Political Science & International Relations at the University of Delaware, Ba said India consults with the regional players as also tries to work with other major powers including US, China and Japan as it enhances its involvement.
"It is a large economy. It is a large power. You can't get away from China," she said.
India is, though, making moves to grow its engagement in the region and sustained attention is required on its part, she added.
"It is involved institutionally and I think that's a start," she said.
