The Chinese government has made clear Thursday that it will continue its proactive fiscal policy in the second half of this year to maintain its economic growth as government leaders reiterated the stance, for there are still uncertainties ahead.

Finance Minister Xie Xuren told local financial bureaus at a conference in Beijing on Thursday that the proactive policies, which included increased investment from the government, tax cuts and subsidies to low- income families, had taken effect in stimulating the recovery of the national economy.

The Chinese economy expanded 7.9 percent from a year ago in the second quarter of this year, driven by a surge of fixed-asset investment backed by government fiscal policies.

The economic growth rate accelerated from the 6.1 percent in the first quarter of this year and the 6.8 percent in the fourth quarter of last year.

To weather the global economic recession, the Chinese government unveiled a four-trillion-yuan stimulus package in November to revive the world's third largest economy, which was slowed by tumbling exports. The central government promised a 1.18 trillion yuan investment.

By the end of June, 591.5 billion yuan (US$86.6 billion) out of the total investment from the central government had been allocated, which boosted a 33.5 percent jump of fixed-asset investment in the first half of this year. It was the highest level in the last five years.

The ministry's decision came as Chinese leaders vowed to continue the current policies.

Chinese President Hu Jintao said Thursday that China should adhere to its proactive fiscal policy and moderately easy monetary policy to ensure a stable economic growth as the recovery is not yet solid.

Premier Wen Jiabao has reiterated that the economy is in a crucial phase and rebounding. He pledged to maintain the current macroeconomic policies and fully implement its four-trillion yuan stimulus package.

Xie said the government will implement the fiscal policy "at full swing" in the second half of this year and speed up allocation of investment from government, which, Xie hoped, would stimulate private investment.

Yang Zhiyong, researcher of the Institute of Finance and Trade Economics at the Chinese Academy of Social Sciences, a government think tank, said that currently the proactive fiscal policy had a limited impact on pushing up private investment. It is hard for private investment to enter monopolistic sectors, he added.
