Barclays Capital cut China's GDP growth forecast from 8.4% to 8.1% for 2012 citing the downturn in the euro-zone. Investments are expected to fall next year but domestic consumption will play a role of stabilizing factor, reported Barclays. CPI is expected to ease from 5.5% projected in 2011 to 3.2% in 2012 due to decline in exports and risk of overcapacity, Barclays added.
