Editor's note

One hundred years ago, a formal international civil service was first created. Its aim was to promote and maintain a rules-based world order. So has it stood the test of time? Henning Melber thinks so, and explains why.

Minerals are widely held to be at the heart of ongoing conflict in the eastern part of the Democratic Republic of Congo. That’s because the mines they come out of are believed to be controlled by armed groups who use revenue to fund their activities, earning them the label 'conflict minerals'. Responsible sourcing initiatives are meant to address the problem. Peer Schouten explores whether they do the job.
