Ammon News - China's top 100 supermarket enterprises maintained growth in online sales last year, data from the China Chain Store and Franchise Association showed Sunday.

In 2021, online sales of China’s top-100 supermarkets went up 40 percent year-on-year, amounting to $15 billion, according to the association.

The total number of stores owned by these enterprises gained 2.9 percent from a year ago to about 30,000, with 11 firms logging a year-on-year growth of over 5 percent in sales revenue and store numbers.
