Correct, but Apple follows US law first and Chinese law second. And Huawei follows Chinese law first and US law second. For example the US could block Apple from selling iPhones in china. If they didn't listen the US government could (theoretically) have the board arrested. Same story with China and Huawei. What this means is that China could tell Huawei to shut down their infrastructure in the US. Wether they would actualy be able to do so is unknown, but that that isn't a risk that makes sense to take.
But to your point, China has more control over Apple than the US does over Huawei as iPhones are assembled there (with most components beinf made in Korea and Taiwan).
