The G20, or Group of 20, met for the London Summit of 2009, and ratified a contentious pact over aid to provide bailout assistance to developing countries to help keep them out of bankruptcy. This followed on the heels of the G20 protests of the day before.
[...G20 Leaders...] committed to $1.1 trillion in additional loans and guarantees to finance trade and bail out troubled countries. [...] Giving teeth to an endorsement of free trade at the last summit in Washington, the countries agreed to “name and shame” countries that erected trade barriers. They also pledged $250 billion in financing for trade. [...] The Group of 20 pledged to triple the resources of the International Monetary Fund to $750 billion — through a mix of $500 billion in loans from countries, and a one-time issuance of $250 billion in Special Drawing Rights, the synthetic currency of the Fund, which will be parceled out to all its 185 members. [...] Britain began talks on Wednesday on a tax information exchange agreement with Liechtenstein, an Alpine principality used by wealthy Europeans and others as a place to stash money. [source]
