The United States government began measures today to end its special status with Hong Kong, one month after Secretary of State Michael Pompeo told Congress that Hong Kong should no longer be considered autonomous from China. These include suspending export license exceptions for sensitive U.S. technology and ending the export of defense equipment to Hong Kong. Both the Commerce and State Departments also said further restrictions are being evaluated.

The U.S. government’s announcements were made a few hours before news broke that China had passed a new national security law that will give it greater control over Hong Kong. It is expected to take effect on July 1, according to the South China Morning Post.
