Sorry but it is the only way that will work in these countries:
Identify and profile the needs of the key players with assistance of the locals and address those needs.
We call it corruption but it is their way of life and art of making a deal.

I have seen this in the Philippines too well, can't imagine DRC any different.
For example only those win an election who has the most money to bribe the voters. We refused to support my wife's brother but he still won in his province because he has so many kids working overseas to send this bribe money.
