U.S.–China & China's Diplomacy

The U.S.–China temperature swung back toward friction on Taiwan in this window, and it is the first hard test of the Washington summit's "constructive strategic stability" formula. There was no new direct U.S.–China contact to report after Xi Jinping's Sept 23–25 state visit ¹. What replaced it is confrontation: Taiwan's receipt of U.S. F-16Vs, an FBI spy arrest tied to Lai Ching-te's family, and a U.S. intelligence judgment that a Chinese move on Taiwan before 2028 is less likely — all met with Beijing holding Washington to the summit's own language ².

Beijing's Taiwan demand is unchanged in content and still one-directional, but it now has a firmer anchor. Zhang Han had framed cross-strait peace as the U.S.–China "greatest common denominator" and an "inherent part" of the constructive strategic stability relationship ³. On Oct 6, Guo Jiakun folded that into a harder instruction: the U.S. must "implement the important consensus of the China–U.S. heads-of-state meeting," adhere to one-China and the three joint communiqués, and handle Taiwan "cautiously" ². The novelty is the citation — Beijing now points to the summit document to bind Washington, rather than to any reciprocal U.S. commitment.

The concrete deliverables run against Beijing's ask. Taiwan has received two F-16Vs and plans 64 more this year, and Guo said China "firmly opposes" U.S. arms sales to the island ². In parallel, the FBI arrested a California woman accused of surveilling Lai Ching-te's son at Chinese officials' behest — a charge Guo said he was unaware of and dismissed as a "China spy" smear ². Reuters also reported that U.S. officials now judge Beijing's pre-2028 "invasion" probability to be falling, which Beijing rejected as external interference in an internal affair. Read together, the summit mood has not slowed the U.S. arms pipeline or the intelligence friction.

Because direct engagement is thin, Beijing's posture is read from its other diplomacy — and it is building alternatives. Guo welcomed Putin to the Shenzhen APEC leaders' meeting in November, framing it as a productive APEC "China year" ⁴. At the UN Human Rights Council's 63rd session on Sept 30, China used the "Friends of Global Governance" to table a 94-country statement on "correcting international human rights governance," citing backing from nearly 160 countries for the Global Governance Initiative ⁴. The GDI's 5th-anniversary dialogue drew 300-plus guests, with Han Zheng pledging 10,000 engineers for developing countries, and Indonesia was welcomed as a first founding member of the World AI Cooperation Organization ^1,5.

The counter-signal is that none of this has produced a U.S. result — and the key opening remains unanswered. TASS pressed twice, on Sept 29 and Oct 3, on a Kremlin-suggested Russia–China–U.S. trilateral on the Shenzhen APEC margins; Beijing's published answers avoid it, offering only warmth toward Putin ^6,4. As host, Beijing can enable that meeting or let silence stand as the signal. The parallel front is Japan, where Guo marked the 54th anniversary of the China–Japan Joint Statement by blaming Tokyo's sitting leader for calling a Taiwan contingency a "survival-threatening situation" (存亡危机事态) ⁶. On Iran, Wang Yi offered mediator language — political settlement, opposition to force, return to the Islamabad Memorandum of Understanding ⁷.

The friction is also regionalizing. On Oct 6, Guo asserted Chinese sovereignty over Huangyan Dao and Nansha features including Zhongye Dao and Tiexian Jiao, rejecting Philippine claims that Chinese military and coast guard harassed its aircraft and vessels ². That is adjacent to the U.S. alliance network rather than a U.S.–China exchange, but it raises the same question of whether Beijing's assertiveness is coordinated with its mainland posture or simply parallel. It also keeps a second front warm while the Taiwan file hardens.

Watch four things: whether any U.S. readout adopts "oppose Taiwan independence" verbatim; whether the remaining 64 F-16Vs trigger a Chinese counter-measure; whether Beijing answers the trilateral before Shenzhen; and whether the Japan rhetoric hardens into measures. Until one lands, the read is a China that is holding Washington to a summit it can cite, hedging through Global South institutions, and not yet negotiating on the files that matter.
