Chinese authorities have issued penalties against seven e-commerce platforms for violations including food safety.

The State Administration for Market Regulation (SAMR) imposed fines for a series of “ghost kitchen” food delivery cases.

Citing the food safety and e-commerce laws of China, SAMR ordered the platforms to correct their illegal activities, suspended the addition of new shops for periods ranging from three to nine months, and imposed fines and confiscations totaling 3.6 billion yuan (U.S. $530 million).
