This bill prohibits the Department of Defense from entering into contracts with online tutoring services that are owned by entities from certain foreign nations. It amends an existing law to expand the scope of these prohibitions beyond just the People's Republic of China. The legislation introduces and defines "country of concern" to specifically include China , Russia , Iran , and North Korea . By doing so, it ensures that the Department of Defense avoids contracting with services linked to these countries, thereby addressing potential national security vulnerabilities related to data access and influence.
