With the world gripped in financial crisis, the expertise of Prime Minister Manmohan Singh, a highly acclaimed economist, was much in demand as he met various leaders, including US President George Bush.
Every leader the Prime Minister met sought his opinion on how to deal with the financial meltdown, officials said.
The issue came up in a big way during his meeting with World Bank President Robert B Zoellick.
Singh, a World Bank economist-turned politician, is expected to speak on the subject in his presentation at the United Nations General Assembly.
