Hi, I'm Johnny diamond and from the BBC World Service, this is the global story.
It's more than four times the size of France.
It holds untold mineral wealth in its soil.
And once again, it is the violent playground of its neighbors.
The Democratic Republic of Congo's history is drenched in blood
from colonial Belgium through to the wars of the 90s.
And outsiders have treated the country and its people as something to be exploited and fought over.
But the latest nation to stand accused of bringing violence to the DRC may well surprise you.
Neighboring Rwanda is a byword for tragedy.
Genocidal violence led to 800,000 deaths there three decades ago.
Since then, its recovery has been hailed as a near miracle of development and good government.
So today we're asking,
why is Rwanda being accused of backing the militia bringing bloodshed to eastern Congo?
With me Today is the BBC's deputy Africa editor, Anne Soy.
Hi there, Anne.
Hello, Johnny.
And I want to start this episode right, rather strangely,
perhaps not in DRC in the Democratic Republic of Congo,
but over the border in Rwanda, because it's there.
And what happened there that drives so much of what we're talking about today, isn't it?
