China's economic planning agency, the National Development and Reform Commission, has approved $156 billion in new infrastructure projects, new subways, highways and other projects in recent weeks. The response is more carefully planned than the stimulus projects in 2009-2010, which are now seen as excessive response creating the prospect of bad loans in the banking system and causing inflation. The stimulus spread over 2 years, 2009 and 2010, was by government's initial estimates about 4 trillion yuan and this does not include additional local government spending as the government encouraged spending. This time the stimulus is about 1 trillion yuan or $158 billion, 2% of GDP, spread over 4 years, with projects going through careful review, according to Nomura economist Zhang Zhiwei. The Chinese government wants to avoid losing gains made in controlling a property bubble and holding down inflation.
