Indian Prime Minister Manmohan Singh Wednesday left for the United States to attend the third G20 summit in Pittsburgh, said Indian officials.

In his departure statement, Singh said he would seek greater voice for developing countries in international financial institutions at the summit.

Stressing the world economy is not "out of the woods" yet, Singh said it was necessary for India to engage in the management of the world economy because "we have a lot at stake, and a lot to contribute".

Singh also emphasized the need to carry the process of reform of international financial institutions to give "greater voice and representation to under-represented countries".

India would also like to see a strong message to emerge from Pittsburgh against protectionism in all its forms, whether trade in goods, services, investment or financial flows, said the prime minister.
