ADB's report came a day after the World Bank revised its 2008 China growth forecast to a lower 9.4 percent, warning the country of rising inflation and weaker exports.
The Chinese government said in March it aimed to maintain the country's economic growth at eight percent this year, while the inflation target was fixed at 4.8 percent.
The report said developing Asian economies would register "solid growth" in 2008, despite a slowdown in major industrial economies, surging food and fuel prices and the credit crisis which began in the United States.
It said developing Asian economies would expand 7.6 percent in 2008 and 7.8 percent in 2009, against an average 8.7 percent in 2007, the highest growth in almost two decades.
However, the bank also warned Asian countries of the risk of an inflation spiral in Asia, as the World Bank did a day earlier in its report.
It said inflation in the region was expect to spike in 2008 and could hit a decade-long regional high, and urged countries to tackle the problem.
"Inflation is expected to rise to 5.1 percent in 2008 and gradually slide to 4.6 percent in 2009."
