re: a reason i ask the question

Because if the pick-up is assembled in the USA, then it's an otherwise
25 percent import tax on (imported) pick-up trucks that are not
assembled in USA, according to hearing held by Senator Dorgan of N.D.
today via c-span.

Thus, Korea & Thailand where p/up trucks are made, aren't being
enticed/encouraged to export their pick-ups to USA.

Does Toyota assemble its pick-ups in the USA?

Does Mazda assemble pick-ups in USA, or because it's partly owned by
Ford, then perhaps it doesn't pay the tariff (?).

I've read that China has plans to export pick-ups to USA, apparently
despite the twenty-five percent tariff:

There's such an article I saw today or yesterday in the business
section of the NYTIMES in which China buys in toto a Brazilian truck
factory to re-assemble piece by piece and make 'em for half of what it
costs to make 'em ($15,000 in China versus $30,000 in USA or perhaps in
Brazil).

I'm not making this up.
