One thing you can definitely do is stop buying a lot of cheap made-in-China shovelware you don't need. It is more expensive and more difficult to purchase items with origins in countries with environmental and labor protection, but not impossible.
You don't need to go all the way to "origins in countries with environmental and labor protection" in order to not buy from china. There's plenty of countries with equally lax environmental and labor protections that are far less oppressive and authoritarian while offering goods at close to the same cost.
You could also recognize those protections were put in for a reason and thus support the economies of countries willing to put up with the economical handicap of enacting them in order to better the overall lives of its people.
I'm just skimming and here's some interesting parts (no summary is currently available)
> “(2) instructing the United States Consulate in Hong Kong to maintain an active list of individuals whom are known to have been detained, arrested, or otherwise targeted by the Government of Hong Kong or of China, or intermediaries of such governments, as a result of their participation in the 2014 protests, to facilitate the cross-checking of visa applications for Hong Kong residents;
> “(4) instructing personnel at the United States Consulate in Hong Kong to engage with relevant individuals in the Hong Kong community to proactively inform them that they will not face discrimination when applying for a visa to the United States due to any adverse action taken against them by the authorities as a result of their participation in the 2014 protests or other peaceful pro-democracy or human rights demonstrations.
There's also a lot of talk about the social credit system, China becoming a tech hub (they even mention that HK is being used to export stuff into China that shouldn't be), forced confessions, sanctions, and lots about human rights.
