Walmart raises stake in China shopping website

Walmart, the world's largest retailer, is planning to buy a majority of the Chinese shopping website Yihaodian as part of its expansion in China.

The BBC's Sharanjit Leyl reports on how Walmart hopes to capitalise on the growing number of Chinese who do their shopping online, as the 'bricks and mortar' competition between foreign supermarket operators in Chinese cities becomes more intense.
