The World Bank has raised its growth forecast for China, saying stimulus measures and approval of infrastructure projects will help boost growth. It added that the pick-up in factory output and investment suggested that China's economy was bottoming out. The bank said it now expects China's economy to grow by 8.4 per cent in 2013, up from its earlier projection of 8.1 per cent.A slowdown in China's growth in recent months had prompted policymakers to announce various stimulus measures. These include two interest rate cuts since June, and the approval of infrastructure projects worth more than 150 billion dollar. The bank, in its report, said the impact of easing credit conditions and public investment in infrastructure is beginning to show and is expected to continue to be felt in 2013.
