I am not familiar with either culture, but I’d guess that he does.

and asked me out on a date again

Was this specifically described as a date? If so, I’d suggest that this is the way in to politely raise this. In fact even if it was ambiguous, it still is the way to do it: “Just so that we are both clear, although I enjoyed meeting you the other night, I don’t want to take things any further than these casual meetings.” or similar. I’m assuming that you did enjoy it - or you wouldn’t be considering another one.

You could restate that you will soon be moving (people can be incredibly selective about what they take in and what they don’t) if you want to - although you shouldn’t need to give a reason if you don’t want to.
