GUANGZHOU, China — Chinese authorities have introduced a slew of legislation in the past few months, largely aimed at the tech sector — a move that’s spooked investors and wiped out billions of dollars in value from the country’s internet giants.The legislative onslaught began in November last year when the huge initial public offering of billionaire Jack Ma’s financial technology company Ant Group was suspended.Since then, regulators have introduced anti-monopoly legislation focused on the so-called “platform economy” which broadly refers to internet companies operating a variety of services from e-commerce to food delivery. Regulations have also aimed at bolstering critical data security and protection laws.As a result, high-profile technology companies have faced investigations and punishments.E-commerce titan Alibaba was fined $2.8 billion in an anti-monopoly probe, and China’s largest ride-hailing firm Didi was forced to stop user registrations while regulators conduct a cybersecurity review of the company, just days after its U.S. listing.cnbc.com
