Special edition. Out-of-cycle report on Xi Jinping's 23–25 Sep state visit to Washington — the tier-review trigger named in the 21 Sep weekly. Weekly cadence unaffected; next scheduled report 28 Sep. Sources current to 25 Sep 2026, 12:00 UTC; Xi's departure after the National Archives visit falls after cut-off.

Bottom Line

Warning tier: ELEVATED — held. Summit produced no Taiwan concession and no Taiwan de-escalation. Beijing put a sharper formulation on the record — the US should "oppose" Taiwan independence, not merely "not support" it — and the White House neither adopted nor rebutted it. The $14B arms package remains unapproved. PLA activity dipped during the visit (24 Sep: 10 sorties) but no named-exercise pause long enough to justify a downgrade has elapsed. Muninn downgrade criterion set here: 14 consecutive days without a JCRP or named exercise — earliest 1 Oct (last JCRP 17 Sep).

Correction

The 21 Sep weekly reported Xi arrived Washington 21 Sep. Incorrect. Xi departed Beijing 23 Sep and landed at Joint Base Andrews just before 18:00 EDT, 23 Sep (Washington Post; Joint Base Andrews public affairs). Visit ran 23–25 Sep.

Timeline

23 Sep, ~18:00 EDT: Trump and Melania Trump received Xi and Peng Liyuan planeside at Joint Base Andrews — first time a US president personally greeted a foreign leader at the base since 1962 (The Hill). Cannon salute, 21-member honour cordon, six F-16s and six F-22s static on the tarmac. First Chinese state visit to Washington since 2015.

23 Sep: Bessent announced 90-day trade truce extended ~2 months, to 10 Jan 2027 (previously expiring mid-Nov). Same day, State Council statement carried by Xinhua attacked President Lai; TAO spokesperson Zhu Fenglian labelled the DPP "chief culprit in undermining peace."

24 Sep: Rose Garden military review; Oval Office bilateral; tour of new White House helipad; state dinner (Musk, Cook, Bezos, Altman, Jensen Huang, Pichai attending).

25 Sep: White House tea meeting; joint visit to the National Archives (Declaration of Independence, Constitution, Bill of Rights); Xi departs.

What Was Said on Taiwan

Beijing (Xinhua; PRC MFA readout, 24 Sep): Xi said China hopes the US will "adhere to the correct position of opposing 'Taiwan independence'" and "handle the Taiwan question with prudence to lay a solid foundation for bilateral strategic cooperation." Beijing's position on "safeguarding national unification and territorial integrity" described as clear. Bloomberg characterised this as Xi's first public call for Trump to change Washington's decades-old formulation.

Xi, broader framing: invoked the Thucydides Trap — risk of war between rising and incumbent power "can be overcome." Called for the two militaries to "maintain regular dialogue and improve mechanisms for crisis communication and prevention."

Washington: White House readout of the bilateral did not mention Taiwan. Trump did not answer a reporter's question on Taiwan while standing beside Xi; press pool was brought in for the helipad tour, not a policy availability. No indication the administration will change its "does not support" wording (wire takeaways, 24 Sep).

Formulation gap: US standing language — "does not support" Taiwan independence. Beijing's ask — "opposes." Adopting "oppose" would be the most significant US declaratory shift on Taiwan since the 1998 "Three Noes." Status 25 Sep: not adopted; not rejected on the record.

Taipei (MOFA, 25 Sep): Rejected Xi's remarks as "distorting facts." ROC and PRC "not subordinate to each other"; Taiwan's sovereignty belongs to its people; "Taiwan's future can only be decided jointly by the people of Taiwan through democratic means." Lai (19 Sep, pre-summit): military and civilian resilience must be strengthened to preserve the status quo.

Arms Sales

$14B FMS package — still frozen. Not approved before, during, or after the summit. Held since the May Beijing summit, when Trump called it "a very good negotiating chip." Beijing had pressed pre-summit for a halt under its reading of the 1982 Third Communiqué (Taipei Times, 23 Sep).

Rubio (UNGA, 24 Sep): reframed the delay as supply-side — Taiwan sales constrained by US potential needs elsewhere and industrial-base capacity: "when we sell something, that means we don't have it anymore." Contrast Jun 2026 ("under review, not paused") and Jul 23 Manila ("not connected" to a Xi visit). Third distinct public rationale in four months.

Senate pressure (letter, 24 Sep): McConnell, Cornyn, Murkowski, Tillis to Rubio and Hegseth demanding release of: $300M FMF (State declining to obligate), $1B Taiwan Security Cooperation Initiative (DoD unobligated), and the $14B FMS package. Letter cites the "negotiating chip" remark as a concern.

Unaffected: Dec 2025 $11B package (largest to date) in execution; PAC-3 MSE deliveries underway; HIMARS Q4 2026; NASAMS completion 2031.

Non-Taiwan Deliverables

Trade: truce extended to 10 Jan 2027. No comprehensive tariff, rare-earth or soybean deal. Bessent: "There are some deliverables that have not been perfect on the Chinese side" — PRC meeting 25Mt soybean commitment; behind on $17B other farm-goods pledge; rare-earth deliveries "not up to par."

AI: agreement to establish a communications mechanism on significant AI safety incidents; officials to continue talks in coming months.

Iran: Xi urged Trump to end the Iran war through negotiation; PRC condemned US–Israeli strikes affecting Chinese oil imports.

Military-to-military: Xi's call for regular dialogue and crisis-prevention mechanisms — no announced mechanism or date.

PLA Activity During the Visit

24 Sep (ROC MND): 10 sorties, 5 crossed median line (50%), 12 PLAN vessels. Half the 20-sortie days of 19–20 Sep; no exercise designation. Consistent with the documented summit-restraint pattern (FDD, 25 Aug: tactical, not strategic).

CCG east of Taiwan: month-4 rotation (Putuoshan/Daishan) — no reported withdrawal during the visit. No inspection zone; no shipping-closure NOTAM.

Tier Review

Case for downgrade: summit held without rupture; trade truce and AI channel extend engagement to Jan 2027; 24 Sep tempo roughly half the prior week's peak.
Case against: three JCRPs in September (5, 9, 17 Sep) unprecedented in 2026; 18 Sep PLA drone ISR on President Lai; CCG patrol institutionalised; Beijing escalated its declaratory ask; arms package still hostage.
Decision: ELEVATED held. Visit-period lull is the expected pattern and not evidence of reset. Watch the first 7–10 days after Xi's departure.

Polymarket — 25 Sep

Invasion before 31 Dec 2026: 4% ($42.5M traded as of 20 Sep — price unchanged through summit)
Invasion before 30 Sep 2026: 1% ($2.1M)

Market priced no summit shock in either direction.

Assessed Probabilities

1 month: 2–4% — unchanged; truce to 10 Jan gives Beijing incentive to avoid rupture.
6 months: 5–7% — unchanged; truce expiry 10 Jan and $14B decision are the variables.
1 year: 10–13% — unchanged; 2027 readiness target and Party Congress.
5 years: 18–24% — unchanged; quarantine/blockade weighted 2–3× invasion.

Next Inflections

26 Sep–5 Oct: post-summit PLA posture — spike or sustained lull decides tier. 1 Oct: PRC National Day; earliest WATCH eligibility if no named exercise. 10 Oct: ROC National Day — Lai address, historic PLA reaction window. No date: White House position on "oppose" formulation; $14B release; response to McConnell letter; mil-mil dialogue mechanism. 10 Jan 2027: trade truce expiry.
