China's trade surplus has expanded sharply. Customs data released on Wednesday show that in September Chinese exports rose 36 percent year‑on‑year while imports increased 31 percent. As a result, the monthly trade surplus approached $134 billion, and the cumulative surplus for the first nine months of the year reached $938 billion, roughly 8 percent higher than a year earlier.
Given that the fourth quarter is typically the strongest for exports, the annual surplus could exceed the $1.2 trillion record set in 2025.
AI and high‑tech goods at the forefront
Part of the surge reflects price increases: rising prices for semiconductors and raw materials such as oil and metals lifted the value of trade flows. On a volume basis, however, both exports and imports expanded more modestly.
Rapid global demand for services and equipment related to artificial intelligence has accelerated the trend. Exports of high‑tech products increased by nearly 64 percent in September. Bloomberg Economics estimates that this segment accounted for about half of China’s total export growth.
Market shifts and new destinations
Higher trade barriers imposed by the United States have prompted Chinese firms to intensify efforts to find alternative markets. The International Monetary Fund (IMF) estimates that about half of the redirected Chinese trade was absorbed by emerging and advanced economies in Asia, while roughly one‑fifth went to the European Union.
Analysts caution, however, that these favorable headline figures mask growing sectoral imbalances. While AI adoption and China’s manufacturing capacity boost hardware exports, traditional export sectors — such as garments, furniture and toys — are lagging. Some annual growth numbers are also affected by a low comparison base from the previous year.
Related international context
Trade has been a prominent issue in the United States as well. President Donald Trump recently highlighted that U.S. export levels have reached historic highs under his tariffs program and said the bilateral trade deficit with China has fallen. U.S. statistics released on October 6 show the United States’ trade deficit widened to $105.6 billion in August, up 13.7 percent month‑on‑month, with imports hitting a record.
Peter Navarro, trade adviser to President Donald Trump, said on October 9 that U.S. firms are importing significant volumes of industrial goods for investment and that infrastructure related to artificial intelligence is increasing U.S. import demand.
Meanwhile, China recorded a $34 billion trade surplus with the United States in September, the highest monthly figure since January 2025.
Implications and outlook
Current data suggest China’s trade surplus could grow further through year‑end, but the pattern of growth carries risks from increasing sectoral concentration. Price effects, shifting trade routes, and geopolitical trade measures will together shape near‑term risks and opportunities for both Chinese and global trade.
