China's e-commerce market continues to grow by leaps and bounds. The market grew 120 percent between 2003 and 2011 compared with just 17 percent in the US over the same time, according to global consultancy firm McKinsey. It forecast that China's market could be worth between $420 billion and $650 billion a year by 2020.

More specifically, last year online sales revenue in China was put at between $190 billion and $210 billion, only $10 billion behind the US market and growing much more quickly.
