Trade watchers say they are shocked at the latest tactic being used by the US to shore up its tariff wall against Canada after a legal setback last month. US Trade Representative (USTR) launched investigations into 60 economies under Section 301(b) of the U.S. Trade Act of 1974 to determine whether they have failed to impose or enforce bans on imports produced with forced labour. But critics in the Washington beltway say the 301 probes are basically a “show trial” and that the verdict is sure to go against trading partners such as Canada. Canada is being grouped together with China and dozens of other countries for these investigations. The probes will examine whether Ottawa’s forced-labour rules and framework… are sufficient for screening goods produced by child or forced labour. …“This has nothing to do with forced labour,” said Inu Manak, at the Council on Foreign Relations. …He thinks the administration is constructing a pretext to defend the tariffs it’s already planning.
