In China they might get kidnapped for adoption, at least that is what my (Chinese) wife thinks.

Adoption, or far worse.

That happens in places, but probably not in the places where people living here are.

But if you are adopting from a foreign country beware that it is easy to kidnap some baby from a remote village. Some of the less ethical adoption agencies have done this in the past.

When China was adopting kids to abroad, I'm sure that happened. These days, I'm not sure if child trafficking is still a problem, I only hear anecdotes, and its all domestic (because China doesn't allow kids to be adopted abroad anymore except in very rare circumstances).

China is not the only country adopting. There are places in Africa to watch out for. Though many have stopped adopting as abuse was too common for the benefits.

The big issue for China is that they needed kids staying in the country not going out of it. Even in the 00s, they were adopting primarily disabled kids, and I think that has almost stopped now.

Eh, the big issue with China (and Russia that did the same thing recently), is that it was embarrassing when someone did an international documentary and it became clear that many domestic orphans no one Chinese wanted.
