UBS Securities projected China's economic growth to slow to 9 percent in 2011 and 2012 and inflation to hover above 4 percent.

Wang Tao, its chief China economist, said the country's economic growth will slow to 9 percent for two years from 10 percent in 2010 while the Consumer Price Index, a main gauge of inflation, will jump to 4.3 percent this year and 4 percent next year.

The high inflation will bring more hikes in the reserve requirement ratio on banks.
