Asian economies are preparing for potential new United States tariffs following the Supreme Court's ruling against "reciprocal tariffs" and intensified trade investigations under Section 301.

• The U.S. has launched Section 301 probes into manufacturing overcapacity (covering 16 trading partners) and forced labor allegations (targeting 60 economies).
• Key countries potentially impacted include China, the European Union, Singapore, and Malaysia, whose trade agreements with the U.S. are now invalid.
• This shift to Section 301 is seen as a "plan B" for the U.S. administration to legally impose tariffs after the Supreme Court's decision.
