BEIJING -  Growth in China's economy slowed slightly in the third quarter in a sign that tightening measures were taking effect, the government said Thursday. Economists said the peak of the latest boom may have passed.

The 11.5 per cent expansion in economic output for the July-September period kept China on track to surpass Germany as the world's third-largest economy by early 2008.

The growth figure, a decline from the 11.9 per cent rate reported for the previous quarter, suggests China's expansion has peaked, economists said. They said growth is expected to slow further but still stay above 10 per cent next year.

"The shift down in growth _ albeit mild _ has the economy heading in the right direction,'' analyst Daniel Melser of Moody's Economy.com said in a report to clients. "Growth had got to an unsustainably high level on the back of surging trade revenues. But this appears now to have slowed.''

Chinese leaders want fast growth to ease poverty. But they worry that the rapid expansion and an export boom that is sending money flooding through the economy are driving overspending on factories, real estate and other assets that could ignite a financial crisis.

Beijing has raised interest rates five times this year to curb double-digit investment growth, and economists expect one more hike before 2008.

"Due to macro-economic controls, we have turned the economy from being an overheating one to being one of speedy growth,'' a spokesman for the National Bureau of Statistics, Li Xiaochao, said at a news conference to announce the growth figures.

Also in September, inflation eased slightly, with consumer prices up 6.2 per cent over the same month last year, down from an 11-year high of 6.5 per cent in August, the government said.

Authorities have blamed a recent spike in inflation on a shortage of food items, especially pork. They say it should ease as government efforts to encourage farmers to raise more pigs take effect.

Chinese leaders "have managed to weather this latest inflation spike storm and are headed for smoother sailing,'' said Tim Condon, chief Asia economist for Dutch bank ING.

Condon said he expected growth to ease further, falling to 10.5 per cent in 2008.

Bank Paribas economist Chen Xingdong said he expected growth in 2008 to decline by up to two per cent. ge points from this year's rate.

Total third-quarter economic output was 16.6 trillion yuan ($2.2 trillion), according to the statistics bureau.

China's unexpectedly strong expansion has prompted analysts to raise forecasts for this year's growth to as high as 11.5 percent. It would be the fifth straight year of double-digit expansion.

China is on track to overtake Germany in December or early in 2008 as the world's third-largest economy after the United States and Japan. But per capita income for China's population of 1.3 billion people will still be far smaller than in those economies.

China reported total economic output last year of 21.1 trillion yuan, or $2.7 trillion, compared with Germany's $3 trillion. Germany is forecasting 2.3 per cent growth this year, well below China's brisk rate.

Li, the statistics bureau spokesman, said the government also is making progress in efforts to ease dependence on exports by encouraging Chinese consumers to spend more.

Retail sales in the first nine months of the year rose 15.9 per cent, an increase of 2.4 percentage points over the growth rate for the same period last year, Li said.

"Consumption is expected to keep growing rapidly, becoming an important factor in pushing economic growth,'' Li said.

Li said China's growth should not be affected by U.S. credit market turmoil. But he said economic performance in the coming year was uncertain due to rising oil prices and a possible global slowdown.
