> Article seven says in part that “All organizations and citizens shall support, assist, and cooperate with national intelligence efforts in accordance with law, and shall protect national intelligence work secrets they are aware of.
And that's just a nice wording to make it official, russians don't have anything similar yet they keep bribing small and big people all around the world to often perform literal treason of their home country, and quite a few do so for petty sums. Your Chinese relatives can also be just sentenced ie for made up drug trafficking to execution and subsequent organ harvest if say sending them to 're-education' camp won't convince you.
Anybody having Chinese citizenship and any position of power or access to secret stuff should be treated as potential threat and evaluated continuously. Or just not hired. If they are actually serious about such a work they should give up their nationality, if they can't then they are risky. Its a serious stuff by no means, but this is how China plays so literally everybody around the globe has to adjust or suffer subsequent consequences.
