What are the country/world leaders doing to solve this?
UNICEF reports that, "Between 2000 and 2022, 2.1 billion people gained access to safely managed drinking water and the number of people lacking at least basic drinking water services decreased from 1.2 billion to 703 million.” [O]
That’s not everyone but in about 20 years 2 billion more people got access to safely managed drinking water, and the amount of people who lacked basic drinking water dropped by half a billion in the same time. It won’t mean much to the 700 million who don’t have safe drinking water but progress is being made.

I'm not disagreeing, but corruption requires a corrupting company as well, and if we're going the moral route, bribing to get the upper hand on a captive population fits the "evil" definition.
Then again and again, western countries don't really need a more developed third world, and they won't bend over backward to create more competition for themselves. So supporting corrupt regimes has very few downsides from a G20 country for instance.
Banana republics are the most simple example of that, but it doesn't need to be that blatant.
