For two months, the people of Hong Kong waited in suspense after China’s legislature approved a new national security law. The legislation’s details were finally made public yesterday and almost immediately went into effect. As many Hong Kong residents feared, the broadly written new law gives Beijing extensive authority over the Special Administrative Region and has the potential to sharply curtail civil liberties.

In response, the United States began the first measures to end the special status it gives to Hong Kong, with the Commerce and State Departments suspending export license exceptions for sensitive U.S. technology and blocking the export of defense equipment.
