China's indexes rebounded from the morning's doldrums after the release of international trade data and renewed trade tensions between China and Japan. 

The Hang Seng Index declined 0.4%, and the mainland-focused CSI 300 Index edged up 0.07% amid tempered risk appetite. 

 

China's Trade Surplus Widened in August

China's international trade surplus widened in August after exports and imports advanced, the General Administration of Customs reported on Tuesday.  

Exports increased 25% to $401.1 billion, and imports advanced 28.2% to $282.4 billion, resulting in a trade surplus widening by 18% to $119.1 billion from a year ago. 

China's direct surplus with the U.S. expanded to $29.2 billion from $28.0 billion in July, buoyed by strong demand for artificial intelligence infrastructure-related products and pre-Christmas orders.  

China's export sector has benefitted from the global boom for AI infrastructure and renewable energy products, including batteries and solar panels.  

Exports to the members of the Association of Southeast Asian Nations surged 30.2%, and to the European Union advanced 6.6% from the previous year, respectively.  

In the first eight months of 2026, China's trade surplus expanded to $805.5 billion from $785.3 billion, driven by a 19.3% rise in exports and a 27% surge in imports from a year ago, respectively. 

Beijing announced preliminary anti-dumping measures on Japanese imports of chemicals used in semiconductor production, a retaliatory measure in the ongoing Taiwan-linked dispute between China and Japan. 

 

China Indexes and Stocks 

The Hang Seng Index decreased 0.4% to 25,310.17, and the mainland-focused CSI 300 Index edged up 0.1% to 4,578.15. 

Technology stocks led gainers in choppy trading on Tuesday. 

CATL declined 2.5% to HK $558.0, SMIC decreased 1.9% to HK $67.0, and Eoptolink Technology advanced 1.9% to ¥425.0.
