Tesla is bringing LFP battery production in the US. They have been manufacturing other battery types for a very long time.

So you can say they're doing a lot more then competitors to onshore production.

It's a shame the only companies with LFP expertise are in China, so they have to get the know how from them and production equipment at least initially.

Similar thing to how silk ended up in the byzantine empire.

So no, it bears no relation. CATL is a chinese company, controlled like everything else by CCP, Tesla is a western company, controlled by stockholders.
