Wal-Mart and five other companies will invest $500 million in Chinese online retailer 360buy.com. Wal-Mart operates more than 200 stores in China. 360buy.com says it is growing fast, with sales in 2010 at $1.5 billon, up from $200 million in 2008. This coincides with rapid growth and the convenience of online retailing in China. Analysts says 360 buy manages its own goods and distribution, which are mostly consumer electronics. 360buy resembles Amazon in the US. i-Research, a firm in Shanghai, says online retail sales in China are taking off with sales growing from $8.5 billion in 2007, to $75 billion in 2010. Before 360buy the other major online retailer was Taobao.com, a subsidiary of Alibaba, which does not resemble Amazon or 360buy, as it is more of an online bazaar that maches buyers and sellers.
