I think it has to do with existing trade laws that forbid us from doing the same thing to countries under the agreement.
They can slap tariffs on us, but under the current trade agreements, we can’t do the same...nor can we rebate taxes like they can for their own exporters, or we become penalized.
It’s stupid, I know.
Two years ago the WTO ruled against us and we had to stop the foreign tax credits that companies received for exporting product.
The EU and EEC sued the USA stating unfair business practice so we lost our tax credits for exporting.
I am always amazed at how we always loose in WTO decisions.
Fiji films can export and sell film in the USA but Kodak cannot sell film in Japan.
