^^^ Well, if it could never happen again, then we need all the help we can get... like 50 million percent tariffs.
The only reason we lost slave labor over in China, is because Government lifted tariffs so that cheap foreign labor was open to us. Then they allowed the transferring of technology to these countries that would have never developed anything on their own.
We can't compete with cheap foreign labor regardless of tariffs, and its not really that big of an issue. The amount of value added to a blob of plastic by turning it into a plastic fork is significantly less than the service based industries we've supported. Its cheaper and more efficient to import stuff from China because they have major geographical and workforce advantage. Competing to see who can make the cheaper plastic forks is just going to make plastic forks more expensive.
I worked on graphene capacitors, and one of the biggest problems was supply. China is the only country at the moment with the capability of making graphene wafers in a specific manner, because the facility setup required billions of dollars. Acquiring the capital investment, land, permits, and workforce to operate a facility that needs 55,000 workers per shift just isn't feasible anywhere in the US.
Its not a big deal, we just need to focus on what we do best and sell that to countries that do something else. Be mindful of strategic resources and manufacturing, but we don't need to worry about a shortage of plastic forks if relations sour.
Assuming the OP's point is about IP rights of tech firms and stuff, thats kind of a separate issue than what I've talked about to this point. Each person has their own opinion on that, and I can respect that.
