U.S. lawmakers met this week to discuss how to combat the use of child labor in the Democratic Republic of the Congo’s cobalt mining sector which they claim is largely controlled by Chinese mining companies. The issue is part of a larger debate over what the U.S. needs to do to better compete with the Chinese around the world to secure the critical resources that will power next-generation mobility and technology.

The timing of this week’s hearings on Capitol Hill coincides with the release of a new report from the Carnegie Endowment for International Peace (CEIP) about how African countries can become more engaged in the U.S. clean energy supply chain.
