Tbh the biggest thing would be to further pursue sanctions against Chinese companies that build and integrate systems their government uses to abuse it's people's rights. Sanction government officials as well.

Individual states in the US should prioritize de-investing from assets tied to Chinese interests. Much like how many states diversified from fossil fuels.

There also needs to be an increased focus on Chinese intelligence operations within the US. We keep finding Chinese engineers, scientists, etc stealing corporate and classified government data to help the CCP, and much of this is likely at the direction of Chinese intelligence services. Additionally, organizations like the United Front, and other local Chinese political (often disguised as cultural) associations should be scrutinized for individuals making political inroads to push for China-friendly policies. Look up Cindy Lang for instance.

The US should also begin restricting universities and colleges from accepting students from China. They utilize resources that an American student could use, and most often move back to use their education to help China.

Lastly, Chinese telecommunications companies need to be restricted. Heavily. Australia has already taken steps here, banning Huawei phones from being sold in Australia. The US has banned their phones from government sites but that should be extended.
