## Beijing's Mineral Export Curbs: The New Battleground in US-China Tech Competition

The geopolitical tensions between Washington and Beijing have taken a sharp turn toward supply chain warfare. In early December, China announced sweeping restrictions on the export of critical minerals—gallium, germanium, antimony, and graphite—marking an escalation in the ongoing dispute over semiconductor technology and national security.

### The Trigger: US Expands Chip Export Controls

The US administration recently broadened its export restrictions targeting 140 Chinese entities involved in semiconductor development, effectively cutting off Beijing's access to advanced chip-making technology. Facing what it describes as systematic technological suppression, China's Ministry of Commerce responded by imposing mandatory approval requirements on these four strategic minerals that are fundamental to semiconductor production, electric vehicle batteries, solar panels, and military applications.

This move signals a fundamental shift: rather than competing on technological innovation alone, both nations are now weaponizing their control over raw materials and manufacturing inputs.

### Why These Four Minerals Matter

Gallium and germanium are irreplaceable in semiconductor fabrication for consumer electronics, defense systems, and renewable energy infrastructure. Antimony finds its way into flame retardants, energy storage systems, and advanced weapons. Graphite, too critical to overlook, increasingly powers lithium batteries and high-performance computing.

Here's the supply chain reality: the US sources approximately half of its gallium and germanium imports from China, making Beijing's export controls an immediate concern for American semiconductor manufacturers. China dominates global production of these materials, leaving international competitors with limited alternative suppliers.

### A Pattern of Escalation

This December announcement didn't emerge in a vacuum. Throughout 2023, China had already introduced licensing requirements for gallium and germanium exports. By mid-year, pricing for antimony had surged—more than doubling—as market participants anticipated further restrictions. The tit-for-tat dynamic mirrors the broader tech conflict: the US controls advanced chip design tools, manufacturing equipment, and high-bandwidth memory chips; China controls the raw materials feeding those production pipelines.

Both capitals frame their actions as defensive measures protecting national interests. Neither side views the other's restrictions as legitimate.

### The Ripple Effects Across Industries

Semiconductor manufacturers, automotive producers, and renewable energy companies now face a critical juncture. Supply chain diversification is no longer optional—it's urgent. Industry analysts predict accelerated exploration of alternative sourcing regions and investment in domestic mining operations.

The US possesses domestic reserves of these critical minerals, yet domestic extraction and refining capacity remains underdeveloped. The CHIPS and Science Act and related initiatives aim to remediate this vulnerability over time, but these efforts remain in early stages. Bridging the gap between current dependency and future self-sufficiency will take years.

Market observers are watching three key metrics: mineral prices (which have already moved sharply higher), corporate supply chain announcements, and whether the US Department of Commerce issues further retaliatory measures. The semiconductor sector faces the most immediate pressure, but automotive and clean energy industries stand equally exposed.

### The Larger Strategy

What began as US efforts to restrict China's military technological capabilities has morphed into a two-front resource conflict. Export controls on semiconductors are meeting export controls on the minerals those semiconductors require. Neither party can achieve unilateral advantage through restriction alone—both are ensnared in a system of mutual dependency that neither can easily break.

The question facing executives, investors, and policymakers is whether this escalation represents a new steady state in US-China competition or a prelude to further restrictions that could fundamentally reshape global supply chains for decades.
