Here is a cross-checked, accurate, data-based list of the countries that possess the most important rare earth element (REE) resources — focusing on geopolitical, technological, and economic strategic importance. This includes their estimated shares of global reserves and production capacities, as well as which rare earth elements (REEs) are most representative in their resources where such data is reliably available.
📌 What “rare earth elements” are
Rare earth elements (REEs) are a group of 17 metallic elements — the 15 lanthanides plus yttrium and scandium — that are essential to advanced electronics, defense systems, clean energy technologies (e.g., EVs and wind turbines), telecommunications, and precision instruments.

Global Overview — Reserves & Production (Latest Verified Data)
*Production estimates for Brazil vary and are rapidly evolving as commercial operations begin. (Wikipedia)
Detailed Country Breakdown
🇨🇳 China — Dominant World Leader
Reserves: ~44 million t REO (~48–50% of global total).Production: ~270,000 t (~69% of global output).Key Rare Earth Elements in China’s Reserves:Light REEs: Cerium (Ce), Lanthanum (La), Neodymium (Nd), Praseodymium (Pr)Heavy REEs: Dysprosium (Dy), Terbium (Tb), Yttrium (Y)Strategic Importance: China dominates mining, beneficiation, refinement, and separation technologies — giving it outsized influence on global supply chains in electronics, EV motors, defense systems, and wind turbines.

🇷🇺 Russia — Strategic Resource Country
Reserves: ~3.8 million t (~4%).Production: ~~2,500 t.Typical Elements: Lanthanum (La), Cerium (Ce), Neodymium (Nd) among others.Context: Moderate producer with significant resource base, especially relevant for domestic and allied supply chains. (Investing News Network (INN))
🇻🇳 Vietnam — Large Reserves, Low Utilization
Reserves: ~3.5 million t (~4%).Production: ~300 t.Notable Elements: Ion-adsorption clays with potential heavy REE content.Summary: Substantial resource base but severely under-utilized, with export controls limiting raw ore outflows. (Investing News Network (INN))
🇺🇸 United States — Significant Producer with Strategic Focus
Reserves: ~1.9 million t (~2%).Production: ~45,000 t (~11–12%).Representative Elements: Mountain Pass Mine features Nd-Pr rich ore (neodymium/praseodymium).Strategic Role: Major producer with increasing investment in downstream processing to reduce reliance on imports. (Wikipedia)
🇬🇱 Greenland — Emerging Resource
Reserves: ~1.5 million t (~1–2%).Production: None currently commercial.Potential Elements: Neodymium (Nd), Cerium (Ce), Yttrium (Y) based on geological surveys.Outlook: Early-stage exploration with future strategic value potential. (Wikipedia)
Major Rare Earth Elements by Use & Strategic Priority
The REE group comprises 17 elements, but several are most important for technology and industrial use:
