The G20 summit marked the return of the United States to multilateralism.

The G 20 Summit should also be an occasion for affirming some basic principles.

Consider the London G 20 meeting in 2009.

Topolanek wasn t at the G 20 his country is not a member.

Mexico, the G 20 s host, also pledged 10 billion.

The recent G 20 summit occurred with virtually no real preliminary work.

And the fact that France has put food at the center of the G20 is really important.

British Prime Minister Gordon Brown recognized the problem and placed it on the G 20 s agenda.

His silence on Doha at the recent G 20 summit was deafening.

A G 20 summit is not something that happens every day. It is a global event.

The G 20 Seoul Summit may well have initiated that important process.

First, as with the G 20 summit, everyone expected the London Conference to fail.

In view of the G 20 s success, the Pittsburgh summit recognized it as the main forum for international economic cooperation.

The next G 20 summit should implement a fundamental reform of the FSB.

This should be one of the central themes of the next G 20 meeting in Pittsburgh.

PARIS In the aftermath of the G20 Pittsburgh Summit last year, European and American officials insisted that G20 membership was imposing new responsibilities.

The Brisbane summit will be a crucial test for Australia, the G 20, and the possibility of truly global policy coordination.

The G 20 in London was responsive to the concerns and special circumstances of the developing world, which resulted in some big thinking.

The Toronto summit will provide a first opportunity to assess the G 20 s ability to adapt to new conditions.

In September, both at the United Nations and at the G 20 Summit in Pittsburgh, many countries agreed to work on Obama s nuclear agenda.

Only the sheer gravity of the situation brought Germany back within the European realm for the subsequent G 20 meeting.

Last month s G 20 meeting ended up as yet another expensive summit lacking sufficient content and follow through.

June s G 20 summit in Toronto, although not very effusive on trade, did not back away from it.

Following the G 20 meetings in Seoul and the NATO summit in Portugal, the Organization for Security and Cooperation in Europe will hold its first summit in 10 years in Astana, Kazakhstan s spanking new capital city.

It is to be hoped that we will learn the details before the G 20 meets in Seoul in November.

Indeed, the G 20 s Seoul summit in early November exposed a deep divide.

NEW YORK Meetings of G 20 leaders regularly affirm the importance of maintaining and strengthening openness in trade.

Some recommendations by members of Columbia University s Center on Capitalism and Society were sent to last April s G20 meeting.

But prior to the Strasbourg and Prague summits, transatlantic relations will be put to the test at the G 20 summit in London.

That is why all of the commitments made and intentions expressed at the upcoming G 20 summit matter.

YEREVAN Summit season is upon us. Following the G 20 meetings in Seoul and the NATO summit in Portugal, the Organization for Security and Cooperation in Europe will hold its first summit in 10 years in Astana, Kazakhstan s spanking new capital city.

The London G20 summit gave a strengthened mandate to the IMF, while tripling its resources.

We get to the Translators Summit, the Volunteers' Summit, I call it.

NEW YORK There is little doubt that green will be the metaphorical color of choice for world leaders when they gather at the G 20 Summit in Pittsburgh.

France and its European partners, in particular Germany, with which we worked in tight collaboration, will suggest all these points to the G 20.

NEW YORK The Seoul G 20 summit was notable for the increasing political weight of the emerging economies.

The first reason is the premature withdrawal of the stimulus measures agreed upon by the G 20 in London in April 2009.

This is the 20th century.

Or you could view it as the distance from one peak to another peak.

Obviously, holding a G 8 summit just before a G 20 summit, as happened in Canada this June, simply serves to prolong maintenance of separate clubs, which is unsustainable. The G 20 s role should increase further in importance, owing to emerging countries share of global GDP projected to reach 60 in 2030 and to the global nature of the challenges of the twenty first century.

The FSB was created in April 2009 at the G 20 s London summit as the successor to the Financial Stability Forum.

The G 20 summit in Washington in 2008 was the first at which the member countries chiefs of state met since the group s creation in 1997.

At their November 2008 summit the G 20 leaders strongly condemned protectionism and committed themselves not to engage in it.

It is still unclear exactly how much of the 1 trillion pledged at the London G20 summit will find its way to Africa.

The G 20 summit has thus created enormous expectations that internationalism may once again overcome a plethora of economic problems.
