Go read about it.....exploitation.
As an example take the UN policy for it's employees. Its a complicated subject less so in a land where there are less legal safety nets for the abusers.
Basically touching provocatively in public here might not be very sensible. Don't negotiate from a position of economic strength perhaps and definitely avoid the young or apparently young. You are the expat john and in a very weak starting position. Maybe you had strength with local government support before but maybe that has all changed now. Await the new council position.
Time to reassess maybe because the AG here does not believe the john has any rights at all....go research.
There are various kinds of sexual exploitation. I think what you are referring to in your example of UN employees is where a supervisor uses his position of power to molest or engage in sexual activity with a subordinate. The important point here is that the employee is not engaging in a truly voluntary manner.
Another example is the sexual exploitation of minors and children. Legally, a minor in almost all circumstances and jurisdictions is automatically considered unable to consent to sexual activity.
A third example is the exploitation of sex slaves. Women are brought into a country under false pretenses and are then forced into prostitution tp pay off their debt.
The key factors in determining if there is sexual exploitation involved is if the person uses his/her position of power or trust for sexual favors, if the person profits or gains from the sexual services of another, or if a child is involved.
I think you need to do some further reading on the subject. And BTW, I don't need any of your suggestions nor to reassess anything.
