Colombia has ordered Uber to halt its ride-hailing operations in the Andean country in a decision that has sent shivers through technology players in Latin America.

The ruling came down Dec. 20 from the Superintendency of Industry and Commerce, which said that Uber was competing unfairly with taxi services. The app has essentially functioned for years in Colombia in regulatory limbo⁠—the Technology Ministry declared ride-hailing apps legal, while transportation authorities said they were breaking the law.
