China macroeconomic, policy and external-relations outlook: Goldman Sachs highlights stable US-China relations, tighter RMB-management attention and a likely September PMI rebound

Overview

This short China macro update covers the Trump-Xi summit, the PBOC's third-quarter monetary-policy communication and Goldman Sachs' expectations for September activity surveys. Its central message is one of near-term stability rather than resolution: bilateral tensions persist, FX management has gained prominence, and PMIs may improve on seasonal and weather-related support.

Core views

First, Goldman Sachs interprets the September 25 Trump-Xi summit as signaling a shared interest in preserving the US-China status quo through 2026, supporting successful APEC and G20 meetings. The official readouts emphasized different elements: the White House highlighted progress on fentanyl controls and President Trump's request for increased refined-petroleum-product production, while China's account placed “constructive strategic stability” ahead of specific trade and tariff agreements. The report stresses that references to US concerns over rare-earth and other critical-mineral supply shortages indicate that these materials remain effective leverage for China. Accordingly, it views many bilateral tensions as unresolved despite the constructive tone. Second, the PBOC's September 19 third-quarter Monetary Policy Committee meeting, with its statement released September 24, left the broad monetary-policy stance largely unchanged from the second-quarter minutes. The meaningful addition was language calling for prevention of “herd behavior” and the “self-reinforcement of irrational expectations” in FX markets. Goldman Sachs reads this as a greater policy focus on preventing an RMB appreciation overshoot ahead of the usual year-end foreign-exchange settlement rush. Third, Goldman Sachs expects China's September PMIs to rise when released the following Wednesday. High-frequency indicators were broadly unchanged month to date, and its seasonally adjusted Emerging Industries PMI had edged lower, but the institution expects quarter-end residual seasonality and better weather to provide support. Its forecasts are for the official NBS manufacturing PMI to increase to 50.4 from 49.8 in August and for the NBS non-manufacturing PMI to rise to 49.4 from 49.0.

Analysis framework

The report combines official US and Chinese summit readouts to assess bilateral-policy signals, compares the PBOC's third-quarter statement with its prior meeting minutes to identify the incremental FX message, and uses high-frequency indicators, an adjusted Emerging Industries PMI, seasonal effects and weather conditions to form its PMI forecasts.

• PBOC Q3 MPC meetingSeptember 19, 2026; statement released September 24Broad stance was unchanged, with an added focus on preventing herd behavior and self-reinforcing FX expectations.

• NBS non-manufacturing PMI forecast49.4Goldman Sachs expects an increase from 49.0 in August.

Impact & implications

The report's interpretation suggests that diplomatic stability does not remove strategic supply-chain frictions, particularly around rare earths and critical minerals. For macro conditions, the PBOC's changed FX wording places RMB appreciation dynamics in focus, while the projected PMI increases point to a potential near-term improvement in activity indicators.

Risks

• US-China tensions remain unresolved despite the summit's constructive language.
• An RMB appreciation overshoot could emerge ahead of the year-end FX settlement period.

What to watch

• The official and nonofficial September China PMI releases.
• RMB movements and evidence of year-end FX settlement flows.
• Whether US-China relations remain stable through the 2026 APEC and G20 meetings.
• Further developments involving rare-earth and critical-mineral supply-chain concerns.
