China's economy reported 7.6 percent of growth in the second quarter, the lowest since the first quarter of 2009 when the global financial crisis was rampant, amid concerns about the slow-down of the second-largest in the world and the strongest one in the major economies.

The National Bureau of Statistics said on Friday that in the first half, the country's economy grew by 7.8 percent to 22.71 trillion yuan ($3.56 trllion). The growth in the first quarter was 8.1 percent.

It is the lowest growth in the past 13 quarters.

China's manufacturing, foreign trade and investment have been slowing down this year, triggering worries about a hard landing of its economy, whose role is more important as the eurozone is still struggling with the debt crisis, the US is still on the way to recover and emerging economies such as India and Brazil are also slowing down.

China's central bank has cut the interest rates twice this year to stabilize the growth. Premier Wen Jiabao also vowed to maintain a stable economy in recent visits in the nation and major conferences.

Leo Abruzzese, global forecasting director at the Economist Intelligence Unit which conducts extensive research on China's economy, thinks the Chinese government's trying to slow down the economy is also a way to cope with the global economy when both Europe and the US are experiencing financial problems.

"If the (Chinese) government were to stimulate the economy hugely the way it did a few years ago, that probably would be the worst thing they could do," said Abruzzese, adding stimulus should be done moderately.

China's growth has been relying on foreign investments and exports, says Abruzzese, adding the Chinese government should drive more domestic consumption.

"China has to get to the point where the consumers in China need to start consuming more. It has to start re-balancing the economy. China is not a wealthy country but it is a middle-class country right now, too," said Abruzzese. "The Chinese government needs to start creating more social safety programs, more social insurance programs, where people then won't feel they need to save quite as much as they do."

Derek Scissors, a senior research fellow at The Heritage Foundation, said China has raised the average of world growth in almost every year of the reform period. It can contribute more to world growth by rebalancing the economy away from investment and toward consumption.

"If China's GDP growth slows but it also rebalances, that is a much greater contribution to the world economy than fast, unbalanced growth," he said.

Scissors expected China to announce GDP growth of 8.2 percent for the full year of 2012.

"However, the days of announcing 10 percent growth or higher are over. For a few years, the range is likely to be 7 to 8.5 percent, then it may get slower. This is natural," he said.
