Personally I think very high tariffs on Chinese products present an opportunity.
China should wait a bit - say a year - and then see what has the lowest decrease/highest increase in imports from the USA.
Those are products which the USA depends on China, no matter what the cost.
China should then export ban those products.
Of course the USA will immediately and desperately import those dependencies via third-parties such as Mexico/Canada/Vietnam/the EU. China should also ban exports of that product to all of North America, except Cuba. Sorry Mexico, it's not personal. Other countries should be given a quota equal to the previous years' imports.
China can also present a list of friendly countries - e.g. Russia, Iran, Pakistan - to whom these restrictions do not apply.
Retaliation should also be considered. For instance, the USA can ban Xiaomi/BBK/Honor from receiving advanced chips, destroying their smartphone business. It can blockade Chinese plane imports by sanctioning COMAC and forcing Airbus/Boeing not to sell to China. It can place OFAC sanctions on Chinese shipbuilders; many in the world will switch to Korean shipbuilders, which are only say ~15% worse. It can force Apple and Google Play to deplatform all Chinese apps, inhibiting the growth of future TikToks. These risks must be weighed.
