Beijing is a major source of financing for projects around the globe that involve the specific minerals needed to facilitate a clean energy transition and achieve net zero emissions by 2050. Yet its financial commitments for these transition mineral operations are opaque and poorly-documented. This dataset is designed to help policymakers, journalists, and researchers understand how Beijing uses financial instruments to bankroll transition mineral operations in developing countries. It systematically tracks over $98 billion in Chinese official sector financial commitments for extraction and processing of critical minerals across 47 low-, middle-, and high-income countries from 2000 to 2023. The dataset contains detailed information on 313 loan commitments and 1 grant commitment from 53 official sector institutions in China during this time period. AidData will publish updated analysis based on this dataset in a forthcoming policy brief that updates Power Playbook: Beijing's Bid to Secure Overseas Transition Minerals, originally published in 2025. This dataset and the forthcoming brief document how Beijing leverages a massive stockpile of foreign exchange reserves to expand its control over key segments of the global supply chain for 31 transition minerals from A-Z including: Arsenic, Cadmium, Chromium, Cobalt, Copper, Gallium, Germanium, Graphite, Hafnium, Indium, Iridium, Lead, Lithium, Magnesium, Molybdenum, Manganese, Nickel, Niobium, Platinum, Rare Earth, Selenium, Silicon, Silver, Tantalum, Tellurium, Tin, Titanium, Tungsten, Vanadium, Zinc, and Zirconium.
