Planning Commission Deputy Chairman Montek Singh Ahluwalia said on Wednesday that G-20 countries should recapitalise multilateral development banks to fund infrastructure projects.

He also said that G-20 nations, that contribute about 80 per cent to the global gross domestic product, have played a successful role in combating global financial crisis.Mr Ahluwalia was speaking at a meeting in New Delhi organised to gather industry inputs in the run-up to the St. Petersburg G-20 Summit to be held in September.
