China's economy, the world's second-largest, grew at its slowest pace in more than two years, latest government figures show. Gross domestic product expanded by 8.9 percent in the three months to the end of December, from a year earlier. That is down from 9.1 percent in the previous quarter. The statistics bureau data showed that growth for the full year was 9.2 percent, down from 10.3 percent in 2010. Analysts said they expect the economy to slow further this year.
