It was fairly limited. Even the mining sector is not hugely developed. The main mineral there is not so much coltan actually, but nickel, but even that has not been fully exploited yet. I believe there were some companies that were starting to look at that.
The other industry is coffee. There's coffee, and tea, but again, it's not.... Burundi is a really poor country. It's a predominantly agricultural country. There's a little bit of tourism, although even that was not very developed. It wasn't really a thriving economy even before this started unravelling.
