Alibaba.com's headquarters in Hangzhou, China

China's Alibaba Group agreed to invest $692 million in a Chinese department store operator as the e-commerce giant looks to bring the benefits and convenience of online shopping to customers who visit real bricks-and-mortar stores.

Alibaba, whose businesses will come under investor scrutiny ahead of the group's planned mega IPO in the United States this year, said it will buy $214 million worth of shares in Hong Kong-listed Intime Retail.
