Plans to introduce its Luma line to China by June 2012 in cooperation with China Telecom. It is betting on Chinese demand for smartphones to recover. Sales of CDMA phones- China Telecom uses CDMA technology- are expected to double to 60 million in 2012 from 30 million in 2011. China provided 17% of Noka sales in 2011, mostly basic or older phones. The challenge is now to get the Lumia line up and running fast. Nokia's timing is right as smartphones are just beginning a surge in China- IHS forecasts an increase from 65 million in 2011 to 120 million in 2012. Nokia's advertising and marketing and close work with China Telecom has also to kick in for it to maximize on this opportunity.
