We need good anonymous reporting and tracking of these issues so they can be logged. 
The only solution I see for these people is to completely cut ties with your family and make yourself uncontactable so that blackmail on your family can't be used. I know that's not realistic for 99% of people, especially students or those who are on a temporary visa.
The ones that signed are sponsored scholarship students that probably represent more than a couple of million dollars worth of investment.
China is more afraid of someone finishing their training, running away and claim asylum. A young trained doctor will easily find shelter in any first world country. >

China has police stations in foreign countries to deal with this. If you are of Chinese descent, you are not safe from the Chinese police in most major western cities >

Anyone else find it weird that we call these police stations? Obviously in western democratic countries these police have no way to effect a legal arrest or detain someone. Unless they step into an embassy. They have no way to legally compel someone to step into a plane and return to China, they operate using blackmail and other underhanded tactics. Supposedly they convince 220,000 people in a year to return in this way. Supposedly 2 passenger planes of people a day are compelled to return to face crimes in China.
Why are so many Chinese people committing so many crimes against the state? How are the Chinese police so effective? Didn't you hear, it's impossible to escape the Chinese police. 
...Are these claims part of the fear tactic? >

They may not be able to legally compel someone, but they can make the lives of any family still living in mainland China a living hell.  It's not about physically coercing them onto the plane.  It's about insinuating all the terrible things that will happen to mom and dad if they don't do as they're told. >

I don't doubt their blackmail capabilities.
So there's over a hundred Chinese police overseas stations. If we believe the numbers, each station is coercing 6 Chinese people a day. Shouldn't we have something like safe escort services for when Chinese people visit these stations to renew their passport so they don't get blackmailed in person? Require proceedings to be done in English with a real domestic officer present? >

That's the thing about blackmail, though.  It's illegal, but if the people report it, what is the US going to do about what China is doing to their families in response.  Let's assume that these people report the blackmail to the authorities.  The Chinese government then finds some reason to raid their parents' home back in China, convict them of some trumped up charges, and their families suffer political pressure until the person decides to cave in and go back home to mainland China.  No country has a right to interfere with another countries legal system, so China is essentially holding everyone hostage.  The proceedings could all be done in English in front of a domestic officer and it would go along the lines of this:
"Have you heard from your family recently?  I hear that the Chinese government is cracking down on social activists.  Say, didn't your mom make a post criticizing the government not too long ago?  Seemed pretty critical to me, anyway.  You should probably go back home to China and make sure that she's doing well.  It's good to take care of your mother, after all."
And there's nothing that any country would be able to do about it.
