Bangalore, Nov 6 (PTI) Despite positive signs, the American economy still has a long way to go before the "recovery translated to growth on a sustained basis", Frank Wisner, former US ambassador to India, said here today.

"We have a long recovery in front of us", Wisner told reporters after a panel discussion with Indian business leaders on investment opportunities in the US.

He, however, clarified these were his own personal opinions and not reflective of the US government.

The relatively slow recovery in economy is going to have some international impact, he said after a round table discussion on the state of US-India relations and economic opportunity organised by Indo-American Chamber of Commerce.

The conference was hosted by Fairfax County Economic Development Authority and Washington-based law firm Patton Boggs Limited. Wisener is the senior foreign affairs adviser of Patton Boggs.
