With households, enterprises and even governments in advanced economies of North America and Europe deleveraging and restructuring their balance sheets, demand for the products "Factory Asia" makes can no longer be counted on as a primary source of growth. Without shunning globalization or turning inward to "Fortress Asia," developing economies in the region will need to increase cooperation and deepen economic integration, using their huge savings to finance cross-border infrastructure, ease intra-regional trade and investment, and develop more sophisticated financial markets.

The ultimate goal of this integration agenda should be to rebalance the sources of growth more toward domestic and regional demand while keeping the region firmly connected to the rest of the world.

The reason emerging East Asia has done so well in the face of global adversity is simple: it was not part of the problem. It had learned its lessons well from the Asian financial crisis of the late 1990s, its governments reacted quickly with monetary and fiscal stimulus, and businesses and consumers both retained confidence in the region's ability to continue to prosper.

The Asian Development Bank (ADB) estimates that the combined GDP of the region will increase by 8.1 percent this year, much higher than last year's 5.2 percent, and well above the 6.7 percent growth the region posted in 2008. That is quite a high rate of growth considering the world is only gradually climbing out of its biggest economic crisis since the Great Depression.

China, of course, has been at the epicenter of emerging East Asia's economic upsurge. Its policy stimulus package was by far the region's largest. Its growth in first quarter of this year was a torrid 11.9 percent. The second quarter was slightly tamer at 10.3 percent, with investments made last year accounting for nearly 90 percent of the growth. The ADB forecasts the trend will continue, with economic growth this year and next year being 9.6 percent and 9.1 percent.

After being badly hit by the global economic crisis in the early part of 2009, the newly industrialized economies of Hong Kong and Taiwan, and the ROK, and Singapore are forecast to achieve a solid 6.2 percent growth this year, moderating slightly next year.

The economic prospects of the four mid-income ASEAN economies, Indonesia, Malaysia, the Philippines and Thailand, look good for this year after last year saw their poorest performance since the Asian financial crisis. Leading indicators continue to improve in these economies, with strong industrial production growth and rising consumer confidence. This is also true for most other ASEAN economies. Together, ADB expects ASEAN to expand by 6.7 percent this year.

Emerging East Asia's "V for victory" may still be far away. But at the moment, it is certainly forging the right path.
