I want to point out that the fraction of imports/exports between the USA and China is roughly symmetric (by monetary value). In 2022, about 16% of China's exports were to the USA; in 2021, about 17% of the USA's imports were from China.

That being said, you're probably making a valid point about which items are flowing, not just the raw value of goods.

Also, I would think it's generally easier for a producer to find new buyers of what it's already producing, than for a buyer to find a new producer for what it needs.

Edit to add: If we look at the ratio "Exports/Imports", we have about 0.3 for the USA with China, and we have about 3.3 for China with the USA.
