Walmart acquired a minority interest in Chinese e-commerce company Yihaodian, the company announced Friday morning. Yihaodian was launched in July 2008 and currently offers 75,000 products and next-day delivery on essential items from an existing logistics network in Shanghai, Beijing and Guangzhou.

Thanks to the Internet, a lot of what passes for news these days is a report based on a report based on a report with few if any filters in place to verify the accuracy of information. With that qualification in mind, Bloomberg this week reported that Walmart’s market share in China declined to 7.5% in the fourth quarter of 2010 compared to 8.2% in the second quarter. The news agency said its report was based on a report in the English language Shanghai Daily newspaper whose report was based on a report from a market research company identified as CTR.
