China’s growth slows and weakens global demand
China’s real GDP grew 4.3% year on year in Q2 2026, down from 5.0% in Q1. First-half growth was 4.7%. The example shows how slower activity in a major economy can transmit to other countries through trade and aggregate demand.
What happened
China’s National Bureau of Statistics reported real GDP growth of 4.3% year on year in Q2 2026, compared with 5.0% in Q1. Across the first half of 2026, GDP grew 4.7%, while retail sales grew 1.3% year on year.
Why it matters
China is a major buyer of commodities, manufactured goods and services. If Chinese demand grows more slowly, exporters elsewhere may receive fewer orders. That can reduce net exports and aggregate demand, weakening growth in economies with high exposure to China.

Key evidence
Q2 2026 real GDP growth
China’s real GDP grew 4.3% year on year in Q2 2026, down from 5.0% in Q1.
First-half 2026 growth
Real GDP grew 4.7% across the first half of 2026.
Retail sales
Total retail sales of consumer goods grew 1.3% year on year in the first half of 2026, indicating softer household demand than headline GDP alone may suggest.
Best diagram
AD/AS diagram showing weaker export demand reducing aggregate demand
- 1Draw an AD/AS diagram for a trading partner that exports significantly to China.
- 2Start at an initial equilibrium with AD1 and SRAS.
- 3Show weaker Chinese demand reducing the trading partner’s exports, so AD shifts left from AD1 to AD2.
- 4Show the new equilibrium with a lower price level pressure and lower real output, then explain that the size of the shift depends on trade exposure.
Chain of analysis
Step 1
Chinese economic growth slows relative to the previous quarter.
Step 2
Growth of Chinese household and business demand may weaken.
Step 3
Demand for imports from trading partners can fall.
Step 4
Export revenue and net exports fall for exposed economies.
Step 5
Because net exports are a component of aggregate demand, AD shifts left.
Step 6
Real output and short-run economic growth may weaken, with the effect concentrated in export-dependent sectors and countries.
Counter-case
When might the main chain weaken?
Use these conditions to challenge the initial mechanism rather than assuming the effect is automatic.
Trade exposure
The transmission is much stronger for countries and industries that sell a large share of output to China. Economies with little direct exposure may experience only a small effect.
Domestic demand
Strong household consumption, investment or government spending can offset weaker exports, so lower Chinese demand does not automatically cause a recession elsewhere.
Exchange rates and substitution
A depreciation can make a country’s exports more competitive, while firms may redirect sales to other markets. These responses can reduce the fall in net exports.
Cause and duration
A short-lived slowdown may have limited effects. A persistent structural slowdown would have larger consequences for commodity exporters, capital-goods producers and global supply chains.
Judgement
The effect is strongest for economies and sectors highly exposed to Chinese demand; diversified export markets, exchange-rate movements and stronger domestic demand can offset part of the shock.
Use it in a 25-marker
Use the 4.3% Q2 growth figure as evidence that Chinese growth slowed from 5.0% in Q1. Build the paragraph through exports and net trade into aggregate demand. A strong judgement should depend on the trading partner’s exposure to China, the strength of domestic demand and whether firms can diversify export markets.
Practice question
Evaluate the view that slower economic growth in China will significantly reduce economic growth in its major trading partners.

UK public borrowing was £1.8bn in July 2026
Government borrowing finances spending beyond current revenue → fiscal policy can support AD in the short run → debt stock and debt-interest obligations may rise → future fiscal space can narrow

EIA expects Brent oil to ease from about $85 as supply recovers
Higher oil prices → higher transport and production costs → SRAS shifts left → price level rises and real output falls; falling oil prices can reverse part of this pressure
13 August 2026 · United Kingdom
UK output per hour rose 0.7% year on year in Q2 2026
Higher productivity → more output per unit of labour → lower unit costs and higher productive capacity → LRAS can increase → stronger non-inflationary growth and scope for higher real wages
18 August 2026 · United Kingdom
UK unemployment was 4.9% in April–June 2026
Higher labour-market slack → weaker wage bargaining and household income growth → consumption pressure eases → AD may weaken and inflation pressure may fall

Evidence is taken from China’s National Bureau of Statistics first-half 2026 national accounts releases. The effect on trading partners is an economic transmission mechanism and should be evaluated using each economy’s trade exposure.
