China has scaled up support for economic growth recently, with the central bank announcing earlier this week that it will cut the amount of money financial institutions must set aside in reserve by 0.5 basis points from Wednesday, which released 1.2 trillion yuan ($188 billion) worth of long-term liquidity into financial markets. China's economy grew by 4.9 percent in the third quarter compared with a year earlier, down from the 7.9 percent growth seen in the second quarter.

The meeting reiterated the policy stance of carrying out a proactive fiscal policy and a prudent monetary policy, saying that the proactive fiscal policy must be more efficient, tailored and sustainable.

The progress of fiscal expenditure next year must be expedited, and investment in infrastructure should be conducted ahead of the normal schedule, they said.
