Section 301

Section 301 of the U.S. Trade Act of 1974 authorizes the President to take action against foreign governments that violate trade agreements, have unjustified or unreasonable policies, or engage in discriminatory practices that burden or restrict U.S. commerce. The United States Trade Representative (USTR) can initiate investigations on their own or in response to petitions from firms or industry groups, and must seek to negotiate a settlement with the foreign country. If negotiations fail, the USTR can request formal dispute proceedings through the World Trade Organization or other trade agreements, and impose unilateral trade sanctions, such as tariffs or revocation of trade preferences. This law has been used to enforce intellectual property rights, and has been a key tool in recent trade disputes, including the 2018 China-US trade dispute.learn more on wikipedia
