Prior to running for president Trump licensed out his name to other companies who marketed various items under the Trump brand. I don't believe he claimed it was made in the US. When questioned on this Trump has pointed out that there is little manufacturing in the US and has repeatedly advocated in his campaigns for manufacturing to be brought back to the US so that goods wouldn't need to be made in China.
Joe Biden is okay with keeping manufacturing in China though.
But what could Biden do? This isn't communist China where Biden could demand 3 more baby formula factories be built immediately. Nor could he be like "I'll give money to anyone who builds a factory now."
There are only two solutions.
1. Increase Tarrifs. Make it too expensive to get it cheap, which would just make stuff cost more. Which Trump did. How did that work out?
2. Increase fuel costs so the cost of shipping it from China is too expensive vs the savings in cost of manufacturing. Of course to do THAT he would need to start a war in an oil rich area like Russia, the middle east, south America, or the Nordics. Or, I guess, ban oil and petrolium product exports again.
