Tmall to boost supermarket sales

Alibaba-owned site offers incentives to attract customers and score over rivals

Tmall.com, e-commerce giant Alibaba Group Holding Ltd's business-to-customer platform, is aggressively boosting its online supermarket offering with a massive national discount campaign, starting in Beijing.

Experts said the move is expected to pose a major threat to rivals in the country's nascent online superstore market, such as Wal-Mart Stores Inc's yhd.com.
