U.S.–China & China's Diplomacy

The U.S.–China political channel is still frozen, and the Sept 10 readout proved it again: Beijing repeated its line that head-of-state diplomacy carries "irreplaceable strategic guidance" and that "the two sides maintain communication on arrangements for head-of-state interaction within the year" — with no date, no venue, no deliverables attached ¹. That absence, not any new friction, is the frame for this cycle. With the top-level channel stalled, Beijing is spending its diplomatic capital on the Global South and its own neighborhood, and the newest moves — Brazil, a harder Japan–Taiwan line — sharpen a hedge that is widening, not a thaw.

BRICS is the load-bearing lane and it is now realized rather than staged. Xi Jinping attended the 18th leaders' meeting in New Delhi on Sept 12–13, spoke in both sessions, summarized 20 years of cooperation with three keywords — self-reliance, sticking together, fruitful results — and cast the grouping as the Global South's "first phalanx" ^2,3. The deliverables are China-designed: a BRICS AI open-source zone (金砖国家人工智能开源专区), a digital industry cloud platform, and a youth sci-tech exchange plan, all framed as capacity-building so Global South states "benefit equally" from emerging technology. China takes the chair and hosts the 19th leaders' meeting, billed as a third "golden decade" ². This is institutional ambition aimed at exactly the constituency U.S. tech controls exclude.

The clearest new signal in this batch is Brazil. President Lula's chief special adviser Amorim will visit China on Sept 16–17 to meet Wang Yi — a top-tier Global South partner engaging Beijing directly ⁴. That lands on top of the Peru sequence: NDRC Vice Chairman Zhou Haibing met Peruvian energy and mines minister Guillermo Xinye on Sept 11 on minerals and investment, and the day before, National Energy Administration head Wang Hongzhi met the same minister — in China for the APEC energy ministers' meeting — covering oil and gas, power, renewables, new-type storage and green mining, with explicit language about maintaining "global industrial and supply chain stability" ^5,6. Read against the reported U.S. pilot in Panama for a global AI supply-chain certification and traceability platform — which the MFA called a closed, exclusionary "small circle" serving geopolitical calculation ¹ — the resource-and-market courtship of Latin America looks like direct insurance against U.S. certification regimes.

The counter-signal sits on Taiwan and the maritime edge, where Beijing is pressing U.S. allies rather than Washington. On Sept 14, MFA Minister Assistant Liu Bin told a young-parliamentarian delegation from the Japan-China Friendly Parliamentarians League that Prime Minister Takaichi Sanae's "erroneous" Taiwan remarks are the "biggest crux" of current China-Japan difficulties and demanded Japan honor the four political documents ⁴. The same day the MFA pushed back on the Philippines' claim of rights over Mischief and Subi reefs ⁴. With the U.S. channel frozen, this is alliance-cost diplomacy: a signal that aligning with U.S. positions on Taiwan and the South China Sea carries a bilateral price, even when the main U.S. door is shut.

The business-facing door stayed open and concrete. On Sept 10 the NDRC held its high-level roundtable with U.S. multinationals in Beijing under the theme "Embracing the 15th Five-Year Plan," drawing roughly 100 representatives from AmCham China, the USCBC and 60-plus U.S. firms, with officials walking through the 15th FYP outline, inbound-investment policy, the "two new" programs and consumption measures ⁷. On trade remedies, MOFCOM extended the anti-dumping probe into U.S. and Mexican pecans to March 25, 2027 ⁸. The tech-containment fight ran unchanged: CISA's accusation that DeepSeek and Moonshot made frontier-model theft a "core" strategy drew Mao Ning's "pulling away the ladder" (抽梯子) counter — China "builds ladders" via Belt and Road, zero-tariff and "export to China" policies ⁹.

Implications: nothing here overturns the standing judgment. The architecture remains a three-track design — a live but dateless leader-level U.S. channel, an open door to U.S. business, an expanding AI-containment fight — with the diplomacy budget routed through BRICS, Latin America and the neighborhood. The additions this cycle deepen rather than redirect: Brazil joins the courtship list, and the Japan readout shows Beijing pricing alignment for U.S. allies on Taiwan. Watch whether the BRICS AI open-source zone and digital cloud platform become institutions rather than slogans, whether the Panama certification pilot spreads hemisphere-wide, whether the Amorim visit yields named deliverables, and whether the dateless Xi–Trump channel ever gets a date.
