This doesn’t guarantee much in itself. A journalist was murdered there for investigating corruption not that long ago.

And the prime minister’s chief of staff was just arrested over that. Just because illegal stuff happens doesn’t mean there aren’t laws against it.

Sure. That's not the point. The point is corruption increases risk of doing business regardless of whether somebody gets caught. People dying because of investigating corruption only makes the point stronger.

OK, so which EU directive are we dealing with here? Which regulator does Binance answer to?

Their local financial regulator. But the point is EU directives force harmonization of laws governing financial exchanges.
