It's absolutely imperative that the US Govt, and the govts of all democracies, recognize and combat this, and take active measures to protect their Chinese citizens.
One thing that needs to happen if it's not the case already, is ensuring the 5th Amendment - no self-incrimination - protects any who want to come forward about such pressure. They need to know there's a legal safe-haven for them to cooperate with the government.
Democratic governments should probably also look into providing an expedited immigration path for their Chinese citizens' relatives still in China.
Right-wingers may complain about this, but they have to understand that: 1) historically, subjects/victims of oppressive govts are more likely to be allies of US and other democracies, rather than enemies, and 2) innocent till proven guilty must apply universally.
