I traveled extensively in China this year. A strong sense of nationalism keeps the government strong and allows them to trample on the rights of minorities. A trade war / sanctions will only fuel that even further. (Like the humiliation of Germany after WWI helped Hitler to gain power).
The best remedy is to undermine the Great Firewall. And the easiest to hide censored content* in sites that are not filtered (like this one). Just hide it well enough that Baidu etc. cannot get to it.
*: That can include proxies to news sites, facebook etc.
