Chinese copper production hit a record high, driven by favorable conditions from sulfuric acid availability, according to industry data. The milestone reflects the country's continued expansion in metal production capacity amid global demand for the industrial commodity.

Meanwhile, Chinese data-center cooling equipment manufacturers experienced significant stock declines due to heightened competition concerns within the sector. The cooling systems industry, which supports China's expanding digital infrastructure, faces pressure as market participants worry about oversupply and margin compression.

In contrast, battery giant Contemporary Amperex Technology Co. Limited (CATL) demonstrated strong market momentum through a share sale that saw its discount tighten considerably. The improved pricing terms signal robust investor appetite for Chinese technology companies, particularly those positioned in the electric vehicle supply chain.

The mixed performance across different Chinese industrial sectors reflects varying market dynamics, with traditional manufacturing like copper production showing strength while some technology subsectors face competitive pressures. CATL's successful share placement suggests continued investor confidence in leading Chinese tech firms despite broader market concerns.
