China’s exports surged 36.3% year-on-year in September, significantly exceeding market expectations and accelerating from 25% growth in August, as strong demand for technology products and the country’s manufacturing competitiveness drove shipments to overseas markets.

Data released by China’s General Administration of Customs showed that exports reached a record $447.2 billion in September. The growth was substantially higher than the 25% increase forecast by economists surveyed by The Wall Street Journal.

The latest expansion represents one of China’s strongest monthly export performances in years. Excluding distortions caused by the timing of the Lunar New Year, the increase was the largest year-on-year gain since July 2010, according to the supplied reporting.

The export boom, however, presents a complicated picture of China’s economy. It demonstrates the strength of its manufacturing sector, technological capabilities and global supply chains, while also highlighting the weakness of domestic consumption and the growing trade tensions created by its expanding export surplus.

Technology leads China’s export boom
Technology-related products were among the principal drivers of September’s export growth. Semiconductor exports increased by more than 108% year-on-year, while shipments of automatic data processing machines rose nearly 55%.

The figures reflect growing demand for advanced technology products amid the expansion of artificial intelligence (AI), data processing and digital infrastructure.

Taylor Wang, an economist at HSBC in Hong Kong, said demand supported by the global and domestic AI investment cycle had remained a key driver. China’s competitive pricing and established supply chains across other major export categories had also supported growth.

China’s manufacturing base extends beyond electronics. The country is a major producer of automobiles, solar panels, electrical equipment, machinery and a wide range of industrial and consumer goods.

Its ability to manufacture at scale, supported by extensive supplier networks and industrial infrastructure, has helped Chinese companies compete in international markets.

The September figures suggest that overseas demand continues to provide an important source of growth even as the domestic economy faces significant challenges.

Trade surplus reaches $133.5 billion in September
China’s imports also increased, rising 31% year-on-year in September compared with 28.2% in August. However, the value of exports continued to exceed imports by a substantial margin.

The country recorded a monthly trade surplus of $133.5 billion, the second-highest on record, according to the customs data cited in the supplied reports.

A trade surplus occurs when the value of a country’s exports exceeds the value of its imports. It indicates that the country is selling more goods abroad than it purchases from overseas, but it does not by itself establish whether the economy is performing well overall.

China’s cumulative trade surplus reached $938.1 billion in the first nine months of the year.

During January–September, exports rose 21.3% to $3.37 trillion, while imports increased 27.5% to $2.43 trillion.

At the current pace, China is on course to exceed its previous annual trade-surplus record of $1.19 trillion. The scale of the surplus is attracting increasing attention from trading partners concerned about the effects of Chinese manufacturing exports on their domestic industries.

Why a large trade surplus can signal both strength and weakness
China’s expanding trade surplus reflects two different economic forces.

On one side, the country has invested heavily in manufacturing capacity, industrial infrastructure and technological development. These investments have enabled its businesses to produce goods at competitive prices and serve markets worldwide.

On the other side, the surplus also reflects difficulties at home. A prolonged property-market downturn, rising unemployment and weak consumer confidence have discouraged households from spending.

When domestic consumption remains subdued, manufacturers have fewer opportunities to sell their products at home. Export markets consequently become more important for sustaining production and employment.

The problem is particularly visible in industries where China has expanded production capacity faster than domestic demand has grown.

A large trade surplus is therefore not necessarily evidence of balanced economic growth. It can reflect strong export competitiveness, insufficient domestic demand, or a combination of both.

For China, the central challenge is to sustain industrial growth while creating stronger domestic demand for the goods its factories produce.

Weak domestic demand complicates the economic outlook
Despite the export boom, several indicators point to continuing pressure on Chinese consumers and businesses.

The country’s prolonged housing-market downturn has weakened household confidence, while unemployment and economic uncertainty have encouraged consumers to limit spending.

The supplied reporting also cited September consumer-price growth of just 0.9% year-on-year, compared with a 5% increase in factory-gate and mining prices. The figures suggest that businesses are facing higher costs even as consumers remain relatively cautious.

Weak demand can make it difficult for manufacturers to pass higher production costs on to customers, putting pressure on profit margins.

China’s automotive industry illustrates the contrast between domestic weakness and export strength.

Retail car sales fell 28% year-on-year in September, according to the China Passenger Car Association. Dealership sales were also nearly 20% below their September 2023 level.

The decline followed the expiration of a government-backed trade-in subsidy programme that had encouraged consumers to replace older vehicles with electric cars and plug-in hybrid models during 2024 and 2025. However, the broader economic slowdown also appears to be weighing on demand.

At the same time, Chinese car exports have expanded dramatically, rising elevenfold since 2020, according to the supplied reporting.

This divergence illustrates how Chinese manufacturers are increasingly relying on international markets to absorb production that domestic consumers are not purchasing at the same pace.

Currency and tax incentives support exports
China’s export competitiveness is also supported by currency movements and government policy.

The renminbi, China’s currency, has depreciated by more than 14% in inflation-adjusted terms against a broad basket of currencies since March 2022, according to the Bank for International Settlements, as cited in the supplied reporting.

A weaker currency can make domestically produced goods less expensive for foreign buyers when prices are converted into their currencies. However, it can also raise the domestic cost of imported products and raw materials.

Government support has also played a role. The supplied reporting estimated that broad tax incentives for exporters cost China’s finance ministry approximately $318 billion in the previous year.

Such measures can help manufacturers compete internationally, maintain production and protect employment. However, they can also intensify competition with foreign producers, particularly when Chinese companies already benefit from extensive industrial capacity and established supply chains.

Beijing has been reluctant to withdraw export incentives or permit a sharp currency appreciation, partly because manufacturers are already dealing with tariffs and competition from lower-cost production centres.

The policy challenge is to balance export competitiveness with the need to strengthen household consumption and reduce economic dependence on external demand.

Trade tensions intensify with Europe and other partners
China’s export surge is creating increasing friction with trading partners concerned about the impact of low-priced imports on their own industries.

The Association of Southeast Asian Nations (ASEAN) was China’s largest export market in September. Shipments to the bloc increased by more than 52% to $81.7 billion.

Exports to the European Union rose 25.3% to $60.15 billion, while shipments to the United States increased 39.6% to $47.88 billion.

The rapid growth in exports to Europe is particularly sensitive because European manufacturers face competition from Chinese automobiles, electric vehicles, solar panels and other industrial products.

European policymakers are considering how to respond to the growing trade imbalance while maintaining their commitment to international trade and avoiding measures that could unnecessarily disrupt supply chains.

The supplied reporting also noted an understanding reached between China and the European Union concerning exports of Chinese plug-in hybrid vehicles to Europe. The development suggests that both sides are seeking ways to manage trade disputes through negotiations as well as potential restrictions.

The United States has used tariffs to limit competition from Chinese imports since 2018, with subsequent policies maintaining or expanding some of those measures. Europe faces its own policy choices as its trade deficit with China grows and domestic manufacturers seek protection from import competition.

Broad restrictions could provide temporary relief to some domestic industries, but they may also increase costs for consumers and businesses that rely on imported components and equipment.

The debate is therefore not simply about whether China exports too much. It is also about how trading partners can respond to the consequences of China’s manufacturing strength without undermining the benefits of international trade.

China faces a growth model challenge
China’s economic development has long relied on investment, industrial production and exports. This model helped transform the country into a global manufacturing centre, but its limitations have become more visible as the population declines, the property market struggles and household consumption remains weak.

According to the International Monetary Fund’s latest growth outlook cited in the supplied material, China’s economy was expected to grow 4.5% in 2026. The report described this as the slowest expansion since 1990, excluding the exceptional pandemic years.

The challenge is to rebalance growth towards domestic consumption without destabilising the manufacturing industries that employ millions of people and generate substantial export earnings.

A stronger domestic market would give Chinese businesses more opportunities to sell their products at home, potentially reducing pressure to expand exports continuously. It could also help make economic growth less dependent on investment and overseas demand.

However, such a transition requires more than increasing industrial output. It also depends on consumer confidence, household purchasing power, employment prospects and stability in the property market.

China’s September trade figures demonstrate that its manufacturing sector remains highly competitive. Whether that strength translates into more balanced and sustainable economic growth will depend on the country’s ability to address its domestic economic weaknesses.

For the global economy, the consequences will extend beyond China. If exports continue to grow much faster than domestic demand, trade partners may intensify tariffs, negotiate restrictions or introduce other protective measures. The resulting disputes could reshape international supply chains and influence the cost and availability of goods worldwide.

China’s export boom is therefore both a demonstration of industrial strength and a warning that the relationship between manufacturing capacity, domestic demand and global trade is becoming increasingly difficult to manage.
