BEIJING, March 8 (Xinhua) -- China's economy has shown clear signs of recovery since the fourth quarter of 2012 and is developing as planned, a senior economic planning official said Friday.

Shi Zihai, head of the policy research office under the National Development and Reform Commission, said the country's consumption, investment and exports all saw faster growth in the fourth quarter last year.

The three economic driving forces are rebounding and other economic indicators, including the purchasing managers' index and cargo throughput at ports, are also recovering, Shi said.
