This year, companies including Alibaba Group Holding Ltd BABA.O and JD.com Inc 9618.HK offered promotions over several days, with sales widely interpreted as indicative of China"s rebounding post-virus economy.

Alibaba said other top-selling countries this year included Australia, Germany, Japan and South Korea. Over 470 firms exceeded 100 million yuan in GMV.
