Calderon - G20 could contribute more than $430 billion to IMF
"I estimate that it could be a bigger capitalization" than was agreed in April, Calderon told reporters. The G20 is meeting here next week.
In April, the IMF said it had secured at least $430 billion to increase its firepower, but many countries such as Brazil, China, Russia and Mexico itself have not yet said what specific amount they will contribute.
