What does the USA government need in order to believe that companies are moving their pharmaceutical manufacturing to the USA? Finding a site, building designs, testing processes, and more. That takes a few years and huge capital investment. Who is going to pay for that - the countries that currently produce pharmaceuticals, or is the USA government funding the transition?
Does the government intend to impose the tariffs on foreign governments until the facility is built and producing what the USA needs, or will the tariff be removed with a promise? If the tariff remains in place throughout the process, why not wait until there is a USA government change, as that may happen faster that building what Trump wants.
None of it makes sense, especially since the USA government does not want to invest in building pharmaceutical manufacturing facilities in the USA.
"At an evening speech to Republican lawmakers, Trump said he would soon announce "major" tariffs on pharmaceutical imports, arguing the duties would push drug companies to move manufacturing operations to the U.S."
