Just because tariffs are payed by the people of the importing country doesn’t mean they are not harmful to the exporter as well. I mean what do you think the natural consequence of tariffs are? As price goes up for the consumer they are going to reduce their buying of the product to the minimum amount they can get by with, which means less imports into the country imposing tariffs, which means less exports from the country who had tariffs imposed upon them. You forget that tariffs are bad for everyone involved. So no, it is not logical for China to back the Cheeto.
