U.S. tech companies have warned Vietnam's government that a draft law to tighten rules on data protection and limit data transfers abroad would hamper social media platforms and data center operators from growing their businesses in the country.

The Southeast Asian nation with a population of 100 million is one of the world's largest markets for Facebook and other online platforms, and is aiming to exponentially increase its data center industry with foreign investment in coming years.

The draft law "will make it challenging for tech companies, social media platforms and data center operators to reach the customers that rely on them daily," said Jason Oxman, who chairs the Information Technology Industry Council (ITI), a trade association representing big tech companies including Meta, Google and data center operator Equinix.
