Members of the IMF will discuss future action plans after raising €325bn in new funds for crisis intervention, with China and other emerging economic giants taking part.
After weeks of seeking pledges for its "global firewall", the fund said Friday the BRICS group - China, Russia, India and Brazil - had helped put it over its goal.
"We have commitments that are north of €325 bn. That almost doubles the lending capacity of the fund," IMF managing director Christine Lagarde announced.
She was speaking after meetings of the IMF and the finance chiefs of the Group of 20 economic powers.
The figure "signals the strong resolve of the international community to secure global financial stability and put the world economic recovery on a sounder footing."
The BRICS and a handful of middle-sized economies came in with €51bn at the end, though specific amounts were not mentioned.
That came on top of $150bn promised by the eurozone, $38bn from Japan, and $9.5bn each from Britain, South Korea and Saudi Arabia.
Smaller amounts from the Nordic countries, other European governments and Singapore filled out the total.
"We all agreed it was absolutely essential to have the firewall put up at this time," said Tharman Shanmugaratnam, chairman of the IMF's policy-making body.
But, he added, "The firewall is a necessary but far from sufficient condition to resolving the crisis. The real solution has to do with the fiscal and structural reforms that address the real causes of this crisis, particularly in Europe."
The fundraising, coming after the IMF has committed tens of billions of euro to rescues of Portugal, Ireland and Greece, was seen as a test of BRICS support for an organisation they feel is overly dominated by Europe and the US.
It came at a time when worries were mounting again that Spain and Italy could founder and require international support.
In meetings, according to an official at a Group of 24 emerging economies, Ms Lagarde stressed that the new funds were not dedicated to Europe but were there to help all IMF members.
That was reiterated in the IMF statement yesterday.
