US business groups warn Vietnam data rules may threaten investment

HANOI, Sept 10 (Reuters): US business groups warned on Friday a new regulation in Vietnam that will make technology firms store data locally and set up a local office was creating uncertainty and could have a "considerable impact" on investment.

In a joint letter to Prime Minister Pham Minh Chinh, the U.S. Chamber of Commerce, the American Chamber of Commerce Hanoi and the Asia Internet Coalition, said the new regulation would make it impossible for companies to accurately assess the cost of doing business in Vietnam.
