You are correct, however the purpose of the message is moreso to keep China from undercutting us on their goods and materials exported. Their government tends to help drive down the price of good sold in order to inflict harm on other country’s businesses in the same sector. It is hard to sustain a company if all your customers can get your product for artificially cheaper in China. The best way to address this is to remind China that we are customers of their businesses as well and that they would stand to lose more by not playing fairly. If we just told them to go fuck themselves and set excessive embargo taxes on their imports, which Trump did, it had a negative impact on every industry within each respective supply chain. It takes time to build new resource pipelines. Ideally, we need to have multiple sources.
