The largest shopping platforms owned by Alibaba, which also owns the South China Morning Post, plan to give out 30 billion yuan in consumer vouchers and dedicate resources worth as much as 10 billion yuan to boosting traffic, according to the latest announcement from Taobao and Tmall Group, the tech giant’s domestic e-commerce unit.

The platforms also introduced new measures meant to reduce operational costs for merchants, which includes targeting the costs of goods returned by consumers and waiving various commission fees, according to the group.

This marks one of the earliest steps taken by the Hangzhou-based tech conglomerate – which is now in a battle to stabilise its market share in the fiercely competitive domestic e-commerce market – to boost business during China’s largest online shopping festival.
