China's chokepoint strategy: Export controls and the next phase of tech confrontation

In a recent webinar, Martin Catarata and Dr. Jost Wübbeke explored how China’s strategic use of export controls is reshaping global supply chains and intensifying the tech confrontation with the United States. While a temporary agreement between the two powers has postponed some restrictions, the underlying tensions remain unresolved, and the risks for companies are far from over.

The truce is real, but fragile

Martin Catarata described the current U.S.-China agreement as a "ceasefire," not a resolution. China's rapid rollback of certain export bans, such as those on gallium, germanium, and superhard materials, signals a willingness to de-escalate. However, these measures are suspended for only one year, and many controls from earlier in 2025 remain fully in place. The speakers emphasized that both sides are preparing for long-term decoupling, even as they avoid crossing red lines for now.

Licensing complexity as a strategic tool

Dr. Wübbeke highlighted the operational challenges companies face when applying for export licenses under China's regime. The process requires firms to disclose detailed supply chain information, which could be used by Chinese authorities to identify vulnerabilities or exert pressure in future geopolitical scenarios. While general licenses are being discussed, their implementation remains uncertain and may come with strict conditions.

What's still controlled, and what could be next

Despite the postponement of six October regulations, key April controls, especially on heavy rare earths like dysprosium and terbium, are still active. These materials are critical for magnets, semiconductors, and battery technologies. The speakers warned that intermediate products such as magnets and cathode materials may be more vulnerable than raw materials due to China's dominance in refining and manufacturing.
Looking ahead, potential future targets include magnesium, silicon carbide, lithium hydroxides, and even pharmaceutical production technologies. China's ability to selectively apply controls, sometimes informally and company-specific, adds another layer of unpredictability.

Implications for corporate strategy

For professionals in supply chain, strategy, and government affairs, the message is clear: volatility is the new normal. Building resilience will require long-term investment in alternative supply chains, strategic stockpiling, and close monitoring of regulatory developments.
