A new survey of China's economy shows it's much bigger and less dependent on exports than previously thought, which makes its rapid growth look easier to sustain. Financial analysts say the new data could encourage even more foreign investment, according to The Brock Report.

China's government boosted its official estimate of economic output for 2004 by 16.8% as a result of the survey. Using the new figures, China replaces Italy as the world's sixth largest economy. If Hong Kong is added in, which reports its economic figures separately, China would be No. 4 behind only the U.S., Japan and Germany.
