This project introduces a novel geocoded dataset on Chinese overseas mining and exploration projects. We construct a firm-commodity-mine level dataset by 1) identifying the set of overseas mining projects from official records from the Chinese Ministry of Commerce website, 2) coding their geolocation, project owners, and commodities, and 3) linking the project owners to administrative firm-level datasets from China, including firm-commodity-year level customs records. The result is the most comprehensive and granular dataset on Chinese overseas mining projects to date, allowing us to provide new empirical insights into the process behind China’s mining investments and their economic and social impact in the host countries.
