I was just looking it up for South Africa

The EU is South Africa’s most important development partner. Its €281 million bilateral cooperation programme is reinforced by grants for thematic focal areas. Further, the European Investment Bank makes available €462 million in long-term loans.

Did they do that for money or disagreements (e.g. treatment of LGBT people)?

It's more like we made promises we didn't keep (like transferring financial aid, investments in infrastructure projects, etc) and instead Western countries still bleed part of Africa's economy dry and I can understand that they're fed up with it. I only hope that China and Russia won't just be a wolf in sheep's disguise, since they're also imperialist and it'd be naive to expect them to help Africa become a strong contender to their economies.
