In practice nothing the US has done has hurt the CCP. If anything, it has strengthened them domestically.

The major actions the Trump administration has taken against China are: 1) Tariffs which only served to hurt American farmers, considering there was hardly any drop off in Chinese exports to the US (and that’s on paper, since a lot of Chinese exports are now hidden as Vietnamese exports, etc) but significant drop offs in American exports to China. 2) A long sustained battle against 1 Chinese company. While Huawei is suffering, the likes of Xiaomi, etc are still doing just fine. 3) Whining about the nomenclature around SARS-COV-2.

On the flip side, the administration dismantled TPP, which was a decade+ long effort spanning multiple US administrations, and nearly every non Chinese country on the Pacific, that would have actually dealt a huge blow to Chinese bullying by providing companies doing manufacturing in China much more attractive alternatives in the countries surrounding China.
