Vietnam has high tariffs on U.S. goods.
President Trump says "you sell to us, you buy from us" and raises tariffs on Vietnamese exports to half of what they charge U.S. companies.
Vietnam lowers tariffs on U.S. goods.
U.S. sells more to Vietnam. EU sells less to Vietnam.
So while President Trump "has not made tariffs on Airbus", he removed tariffs from Vietnam on Boeing.
There were no particular Vietnam tariffs on Boeign aircraft to begin with.
No. Trump is merely trying to promote a mercantilist deal with Vietnam. It’s not really about tariffs. The tariff is a ploy for mercantilist deals, much like dictatorships like China do all the time. It smacks of socialist central industrial planning. Instead of trying to promote a trade world that does not believe in such things, Trump is trying to duplicate what the likes of China does with national centralized power to promote most favored national companies and industries. Instead of fighting the economic model China presents, Trump is joining it.
