THREAT ASSESSMENT: Strategic Realignment Between U.S. and China Elevates Risks for Taiwan and Global Supply Chains
If U.S. arms sales to Taiwan are delayed to coincide with Xi’s September visit, then the operational window for Taipei’s defense planning may contract without formal policy change; if rare earths access is granted in exchange for strategic restraint, then supply chain dependencies could reconfigure without explicit treaty obligations.
Bottom Line Up Front: The May 2026 Xi-Trump summit signals a shift toward 'constructive strategic stability' between the U.S. and China, increasing pressure on Taiwan’s sovereignty and raising risks of economic coercion, despite limited tangible outcomes on trade or security.
Threat Identification: The emerging U.S.-China framework risks normalizing Beijing’s core interest claims—especially on Taiwan—while leveraging economic interdependence to constrain U.S. foreign policy. President Xi’s invocation of the 'Thucydides Trap' and emphasis on a new 'paradigm' suggest an effort to institutionalize parity and mutual non-interference, particularly regarding Taiwan [IBA, 2026]. Concurrently, President Trump’s ambiguous statements—such as saying he’s 'not looking to have somebody go independent'—have been interpreted as signaling tacit acceptance of Beijing’s position [IBA, 2026].
Probability Assessment: High probability (70–80%) that U.S. arms sales to Taiwan will be delayed beyond Xi’s September 2026 Washington visit, though not canceled, due to diplomatic sequencing [Glaser, German Marshall Fund, 2026]. Medium-term (2026–2028), there is moderate likelihood (50–60%) of reduced U.S. support for Taiwan if economic concessions—such as rare earths access or agricultural exports—are tied to strategic restraint.
Impact Analysis: A U.S.-China accommodation at Taiwan’s expense could fracture alliances in the Indo-Pacific, embolden further PRC coercive actions, and undermine the credibility of U.S. security guarantees. Economically, while China’s review of export controls on rare earth processing equipment may ease supply chain bottlenecks [IBA, 2026], this remains unverified. The lack of confirmed soybean purchase agreements or broader trade deals indicates continued volatility in U.S.-China economic relations.
Recommended Actions: 1) Congress should reinforce the Taiwan Relations Act through bipartisan legislation reaffirming defense commitments; 2) the Biden administration (or successor) must decouple critical mineral diplomacy from strategic concessions; 3) multilateral coordination with Japan, South Korea, and the EU should be strengthened to prevent bilateral great power bargains from marginalizing democratic allies.
Confidence Matrix:
- Summit dynamics: High confidence (based on official briefings and photos) [White House, IBA];
- Taiwan policy shift: Medium-high confidence (based on Trump’s statements and Glaser’s analysis);
- Rare earths cooperation: Medium confidence (U.S. claims unconfirmed by Beijing);
- Agricultural deal ($17bn/year): Low-medium confidence (not corroborated by Chinese sources) [IBA, 2026].
