The main purpose of this legislation, known as the "Stop PRC Economic Espionage Act of 2026," is to strengthen the United States' legal framework against economic espionage by expanding the definition of what constitutes a foreign instrumentality. This aims to better protect American businesses and intellectual property from foreign threats, particularly from countries deemed adversarial. The key provision of the law amends an existing section of the U.S. Code to clarify that any entity based in a foreign adversary country is considered a foreign instrumentality.
