China's consumer price index (CPI), a main gauge of inflation, rose 1.9 percent year on year in December last year, the National Bureau of Statistics (NBS) announced Thursday.

The figure rose sharply from the 0.6 percent rise in November when the index ended nine months of decline, it said.

The producer price index (PPI), a major measure of inflation at the wholesale level, rose 1.7 percent in December from a year earlier, the first monthly rise since December 2008.

The full year figure was down 5.4 percent.

"The rise of CPI had proved that we had successfully get rid the risk of deflation which was a great concern last year," said Ma Jiantang, director of NBS at the press conference.

Positive CPI was due to increasing domestic demand as the economy had gradually recovered, said Xiong Peng, an analyst with the Bank of Communications.

The freezing weather since November also helped push up food prices, and its impact on CPI was expected to continue till March, he said.

In December, food prices, which accounted for about a third of the CPI, rose 5.3 percent and housing expenditures increased 1.5 percent.

"So long as the government macro economic policies are well implemented, we' believe China's grain prices will keep moderate rise in 2010 given the fact of six consecutive years of good harvests and overall supply and demand situation," Ma said.
