China’s second-largest B2C e-commerce site, 360Buy – also known as JingDong Mall – appears to have blocked Alibaba’s product search-engine from indexing its site. Looking at the ‘robots.txt’ file for 360Buy, it now says “User-agent: EtaoSpider Disallow: /” (pictured above) in a move that signals heightened rivalry between the two companies.
