BEIJING, Jan 19 (Reuters) - China's consumer price index (CPI) rose 4.6 percent in December, slowing from 5.1 percent in November, the Hong Kong-based Phoenix Television reported on its website on Wednesday, citing an unnamed source from the central bank.
China's gross domestic product (GDP) grew 10.3 percent last year, it added.
The median forecast of economists polled by Reuters was for December's CPI to rise 4.4 percent and GDP to increase 10.2 percent.
China's full-year CPI in 2010 rose an average of 3.3 percent, while the producer price index increased an average of 5.9 percent in 2010, Phoenix TV added.
