The largest countries, like China and the U.S., should lead by example.

The central focus at the G-20 will be to change the composition of world growth as recovery takes hold: current-account-deficit countries should save and export more and consume less while surplus countries should consume and import more. Some of the required measures will not be popular at home as they impact consumer and trade interests that are vested in the unsustainable status quo.
Yet with Europe a drag on world growth and the U.S. consumer no longer the engine a determined effort to rebalance is essential to take up the slack. What needs to be done?
The best strategy to ensure G-20 momentum is for the largest countries to lead by example. A credible medium-term plan of fiscal consolidation would make the United States the natural leader of the Mutual Assessment process. This is unlikely until after the November 2010 mid-term elections, however, when the bipartisan National Commission on Fiscal Responsibility's report comes due.
The Chinese authorities have a rebalancing strategy that includes nominal exchange rate appreciation, shifts domestic demand towards consumption and shifts job generation more towards labor-intensive production in services as well as manufacturing. They need to follow through. Unfortunately, the euro's recent depreciation against the dollar has put unanticipated pressures on exporters' margins. So has recent labor unrest. Further delay in nominal appreciation will be inflationary and renew international tensions.
The G-20 co-chairs, Canada and South Korea, both have successes from which others can learn.
Few realize that Canada completed a major fiscal adjustment in the mid-1990s when it moved from a deficit of 8.7% of GDP to a small surplus helped by public support for consolidation, a growing world economy and a flexible exchange rate.
South Korea is a graduated emerging market economy which has recovered from severe crises a decade ago. Others can learn from South Korea's strategy to reduce export dependence through domestic investments in human capital, technology and a "Green Korea" strategy of energy conservation, clean energy R&D and energy efficient transportation.
None of these recommendations is a slam dunk because most imply painful macroeconomic and structural adjustments. But the G-20's credibility to restore global growth is on the line.
The outlines of a successful summit began to appear this past week as President Barack Obama, in a June 16 letter to G-20 leaders, committed to reduce the U.S. deficit to 3% of GDP by 2015 and stabilize the debt-to-GDP ratio. On June 19-20 the People's Bank of China committed to greater nominal exchange rate flexibility. Follow through is needed in both countries, and from the Europeans, or renewed global imbalances will threaten global stability.
If growth in the heavily-indebted advanced countries continues to be modest threats of protectionism and political pressures to turn back globalization will rise. Few have much room to maneuver in the face of still-high unemployment.
Thus, the second G-20 summit, and the first to take place in Asia in Seoul in November, may turn out to be extraordinarily fortuitous if President Lee Myung-bak achieves further progress by persuasion and example.
We cannot afford more of the deadlock and inertia of Doha and Copenhagen. To prod governments to act--and to prevent backsliding--the IMF's Mutual Assessment analysis should be published (the April 2010 World Economic Outlook provides a more general but no less urgent assessment). Name-and-shame tactics helped mute protectionist actions during in the heat of the crisis. Such tactics, or a high-profile independent wise persons group, may be necessary to rally public support.
The stakes for the G-20 are high. There must be forward momentum or its credibility and effectiveness will ebb away. And the burdens of global financial crises on future generations will only grow.
