You may also wish to check tariffs on Italian leather shoes - I don't have anything immediately to hand, but the US has traditionally levied tariffs on Italian shoes to protect domestic industry. I believe that Steel was protected in the 1970's against German imports
Ethnicity is a distraction here; protectionism is an attempt to promote domestic industry and workers at the expense of foreign workers. It doesn't matter what color those workers are, the goal is to make sure that domestic workers are rich and foreign workers are impoverished.
If you want to research the question, I'd focus your attention on core domestic industries. (Defined as either (a) Industries with disproportionately large lobbying groups, or (b) designated strategic industries. There will be an overlap). The USA for example wants to maintain a strategic advantage in aerospace, and fears the French and British (particularly when allied).
You limited the question to "manufacturing" - there are a host of counter-market regulations in the farm and service sector. Almost every country has a ridiculous policy about farm products - from Japanese Rice, to US Sugar and Maize to French... well everything (IIRC, Brazil may be an exception). And the current US-European trade treaty will fail because France has imposed protectionist requirements on the entertainment sector.
