    China reported blistering growth for the last three months of 2009 ,raising expectations of interest rate

increases and other measures to head off inflation.

     China has declared that it is recovering from the global economic crisis.

     Ma Jiantang, head of the National Bureau of Statistics, said Thursday the country's economy grew by

10.7 percent in the last three months of 2009.

     Ma says China has managed to quickly hold back what he described as "the sliding of the national

economy". He says China has become the first country, on the whole, to achieve economic recovery and

stabilization.

     According to previous estimates, Ma says China's  gross domestic product for 2009 rose 8.7 percent,

to nearly five trillion dollars.

     This goes beyond the official growth rate target of eight percent. The government has long considered

eight percent growth essential to create enough jobs for the country's more than one billion people.

     At the same time, Ma says some problems and contradictions are natural.

     Ma says the Chinese government will  give more priority  to  restructuring  economic  and  improving

peoples' livelihood.

     To reduce the effects of the global economic crisis that began in 2008 ,China loosened lending

practices, cut interest rates and began massive spending programs. But the government wants to make

sure those measures do not contribute to inflation, which can be politically sensitive in a country where

hundreds of millions of people remain poor.

     Beijing resident Ms Wang says she is worried. She says she thinks prices are rising really fast. She

points to the price of cabbage, which has increased more than 10 times in the past year.

The head  of the  Chinese  Banking  Regulatory Commission, this week said the government will step up

monitoring of banks and rein in lending to prevent speculative bubbles (投机泡沫) in real estate ( 房地

产) and other assets.

     The World Bank on Thursday released a report that predicts China's economy will grow by nine

percent this year. This contrasts with forecasts of 2.5 percent growth rate for the United States and one

percent growth for European economies in , because of weaknesses remaining from the global financial

crisis.
