U.S. Trade Representative Jamieson Greer announced on Feb. 20 that his office will open new investigations under Section 301 of the Trade Act, potentially covering most major trading partners.

Section 301 investigations look into potential unfair trade practices by trading partners, and the Office of the U.S. Trade Representative may impose tariffs on those found to be in violation.
