Orwell said:What is "good governance"? And how do we make sure that "good governance" doesn't get mixed up with idiotic counterproductive economic measures i.e. who gets to decide what "good governance" is? If you are going to say "the country that provides the help", then I see a lot of potential conflicts of interest.
Yep of course there will be conflicts of interest, I can't see how you can avoid it, all you can do is try and minimise those conflicts by having countries work together. That may mean deciding to make the funding available via an organisation like the WorldBank.
As for exactly what the conditions would be that has to depend on the country receiving the aid and what the country (or organisation) is willing to provide in terms of aid. Good governance starts with the simplest things first, I would say the first step is to ensure that the basic rights of people (based pretty much on the UN human rights declaration) are in place. After that it gets decidedly more difficult...
