China's powerful spy satellite success hinges on rare metal it no longer sells abroad

A Chinese radar satellite orbiting the Earth provides near-constant surveillance over Asia and the Pacific, penetrating clouds and darkness. This advanced technology has proven challenging for U.S. scientists to replicate, according to a new study.

The breakthrough behind this capability is not solely attributed to engineering expertise but also to a niche metal. China's near-total control over the supply of this rare metal is a critical factor, raising concerns for the international community.

This situation prompts significant questions regarding its implications for civilian applications, global security, and the potential for technological dependence on China for other nations. The exclusive control over this resource and the associated technology could reshape technological advancements and strategic balances.
