" It’s not just inappropriate, it’s assault. " I'm going to have to stop reading there. Now, of course, I don't know what happened, I wasn't there. What I'm seeing in front of me are glowing pixels that don't constitute a conviction. In my opinion if you believe you've been the subject of assault you ought to approach the police, or probably a lawyer.
Good luck as a foreigner in Malaysia approaching the local police to file a complaint for assault based on a forced kiss against another foreigner who happens to be a millionaire. But that doesn't make it right. Note that it is extremely hard to get these cases to go anywhere in the West where you know the law and where the lines tend to be drawn rather sharper than in Asia (unless there is drugs involved).
I don't have a well thought out comprehensive solution.
