EDIT: briefly searching indicates it’s common in South Korea too. Not sure if it’s just more common in Asia right now or what. Seems like most of the articles about the West I’m finding are about cameras in bathrooms and shit (not that that’s better…).
It can (and does) happen in all countries. For whatever reason though, it seems to be more common in eastern Asia, from what I’ve seen anyway.
If this bothers you (and it probably should), then you should really check every hotel room you stay in, regardless of country. It usually just takes a few minutes when you get into the room, plus you can check for bed bugs while you’re at it.
