A Still-Growing Market

The move on the part of Baidu comes a time when it is shifting its focus to artificial intelligence, recently teaming with NVIDIA Corp.

Blending the offline and online worlds has been the battle cry for Alibaba, Baidu and rival Tencent for some time now. Alibaba and Tencent are having a lot of successes with their efforts, which investors have rewarded with huge surges in their shares prices. Food delivery in China is emerging as a big battleground for the two, which have been pouring tons of money into the sector.

The market for services provided via a mobile phone, whether to place food delivery orders or book beauty treatments, is booming in China. Bloomberg noted in a report at the time the sales of these type of services are forecasted to hit $1.1 trillion in 2017. The food delivery market in China is attractive to both Alibaba and Tencent because it is one of the retail segments that is still seeing growth. Alibaba is currently the largest shareholder in and Tencent, which holds a minority stake, is looking to ramp up investment, according to Bloomberg. Alibaba also has its Koubei service that enables users to book spa treatments and restaurants reservations from their mobile phones.
