Critical Resources and Energy Security: The New Geopolitical Battleground

Control over vital minerals and energy resources remains central to US-China rivalry:

• Dominance in Critical Minerals: China maintains a commanding position in rare earths, lithium, cobalt, and other strategic minerals, leveraging Belt and Road Initiative investments and strategic partnerships across Africa, Central Asia, and Latin America. This dependency constrains Western high-tech and defense capabilities. Countries like Japan are investing in alternative solutions—such as processing asteroid-derived rare earths—to diversify supply chains.

• Deep-Sea Mining and Arctic Competition: Melting Arctic ice, driven by climate change, unlocks new shipping routes and resource deposits—hydrocarbons, lithium, cobalt, and minerals needed for green energy. Russia has expanded its military infrastructure, asserting sovereignty over Arctic resources, while China’s Polar Silk Road initiative seeks to exploit Arctic shipping lanes and deposits, often through alliances with Russia and Nordic nations, thus fueling regional tensions. Deep-sea mining for seabed minerals like manganese nodules accelerates amid environmental and regulatory debates led by the International Seabed Authority.

• Lunar and Asteroid Resource Claims: The ongoing race for extraterrestrial resources remains a flashpoint, with China and the US actively exploring and asserting claims. The lack of clear international governance over space resource rights remains a significant source of tension, risking sovereignty disputes that could destabilize future space activities.

• Economic Decoupling Strategies: The US recently increased tariffs to 15%, signaling a push toward decoupling from China and fostering independent technological and resource ecosystems. This move has ripple effects across global markets, prompting China and its allies to accelerate their own strategic initiatives, further fragmenting the global supply chain.
