I can add to that.
In Africa, when it comes to China, there is very often talk of illegal and artisanal extraction, which causes many problems for the people involved in these activities. That's where competition in the form of dumping can occur. We are therefore focusing much of our efforts on mining issues.
Illegal and artisanal extraction also causes environmental problems. The African governments themselves are increasingly asking us to work on this issue because it causes them security problems and it's a source of frustration for their market.
