The US's reluctance to impose secondary sanctions on major Chinese financial institutions for trading with Iran shows a critical limitation of its economic pressure strategy. The desire to maintain stable relations with global powers like China forces the US to moderate its sanctions, making the threats appear hollow and less effective.

For 30 years, China identified rare earths as a strategic industry. By massively subsidizing its own companies and dumping product to crash prices, it methodically drove US and global competitors out of business, successfully creating a coercive dependency for the rest of the world.

China is leveraging its 90% control over rare earth processing not just against the US, but globally. By requiring licenses from any company worldwide, it creates a chokehold on high-tech manufacturing and establishes a new template for economic coercion.

China demonstrated its significant leverage over the U.S. by quickly pressuring the Trump administration through a partial embargo on rare earth metals. This showcased a powerful non-tariff weapon rooted in its control of critical mineral supply chains, which are also vital for defense applications.

While headlines focus on advanced chips, China’s real leverage comes from its strategic control over less glamorous but essential upstream inputs like rare earths and magnets. It has even banned the export of magnet-making technology, creating critical, hard-to-solve bottlenecks for Western manufacturing.

China achieved its near-monopoly on rare earths not by chance, but through a long-term state-sponsored strategy. This involved providing capital to key firms, funding overseas acquisitions, banning foreign ownership of domestic mines, and consolidating the industry to control global prices.

China is restricting exports of essential rare earth minerals and EV battery manufacturing equipment. This is a strategic move to protect its global dominance in these critical industries, leveraging the fact that other countries have outsourced environmentally harmful mining to them for decades.

China has explicitly stated it will ignore US sanctions against Iran, signaling a major shift in global power dynamics. With the world's second-largest economy refusing to comply, the US's ability to use economic warfare as a primary foreign policy tool is severely diminished.

China is no longer just mirroring US trade restrictions in a tit-for-tat manner. It is now offensively mapping its own supply chains to identify and control global choke points, proactively weaponizing its dominance in critical materials and technologies to exert geopolitical pressure.
