They are in the process of boosting manufacturing as a means to restore China’s economic growth without regard to profitability and are, instead, in the process of flooding international markets with cheap goods that will undermine homegrown manufacturing in many countries, including this one.
China must be an exception to the normal rules of free trade if we are to maintain a decent manufacturing base for clean energy, green transportation and other essential industries. Biden is right to impose tariffs no matter what the free trade purists say.
The US cheats far more on international trade than China does. Indeed, it is the US that has been holding up the WTO because the US only wants "free trade" on its terms. The WTO also ruled in favor of China and the US did not like that. So, like the spoiled child with the ball, the US is trying to wreck the whole system. Fortunately, the rest of the world is still open to trading and benefiting from it.
