The United States has launched an investigation into the economies of 60 countries, including the European Union, Brazil, and Angola, to determine if they have taken sufficient measures to prevent the import of goods produced with forced labour. US Trade Representative Jamieson Greer stated that governments have failed to effectively prohibit the entry of such products into their markets, creating an artificial cost advantage for foreign producers. The investigations, conducted under the Trade Act of 1974, aim to determine if these practices place an unreasonable burden on US commerce and could potentially lead to new import tariffs as the administration seeks to replace revenue lost following a Supreme Court ruling against previous emergency economic tariffs.
