We all know that since its accession into the WTO, China has tried all the ways to promote its exports and in the meantime prevent imports from other nations. Its main tricks were export credits and high tariffs on imports and non-tariff 'regulations' to make it hard for imports to come in. Many of these were explicitly prohibited by the WTO rules. And China has not met most of its obligations under its accession agreement.
Trump took a different approach to tackle it. Instead of blaming China, he just raised the tariffs on Chinese imports. This simple yet very effective method neutralized all the tricks China played. That's why many foreign firms pulled out of China and the unemployment shot up.
The US needs to keep these great tariffs in place. And Biden is doing exactly just that.
