U.S. Trade Representative Jamieson Greer said the probes could yield new tariffs if unfair practices are found.

History

Historical Context

The U.S. Trade Act of 1974 established mechanisms to address unfair trade practices, empowering the U.S. Trade Representative to impose tariffs. This act reflects a shift from protectionism, following the Reciprocal Trade Agreements Act of 1934, which aimed to liberalize trade. Recent investigations into 16 nations, including China and the EU, highlight ongoing efforts to protect American interests and could reshape international trade dynamics.
