China's Investigation: A New Front in the Chip War

The global semiconductor industry is bracing for another round of geopolitical tension as China announces an investigation into US subsidies for mature node chips. This move, seen as a response to the US's Section 301 investigation into China's semiconductor industry, has raised concerns about potential disruptions in global supply chains and the competitive dynamics between US and Chinese chipmakers.

The US's CHIPS and Science Act, signed into law in August 2022, provides substantial subsidies to boost domestic chip manufacturing and maintain the US's competitive edge in the industry. However, China views these subsidies as protectionist measures that distort the global semiconductor market and harm its own interests. In response, China's Ministry of Commerce has stated that it is strongly dissatisfied with and firmly opposes the US's Section 301 investigation, vowing to take all necessary measures to defend its own rights and interests (Xinhua, 2025).



The US's actions, as well as China's response and that of other countries aligned on either side, could have a major impact on the global semiconductor landscape. Companies will need to build diversification and supply chain resilience strategies to deal with the shifting political headwinds. This includes investing in alternative production facilities, diversifying their supplier base, or developing new technologies to reduce dependence on specific inputs.

The semiconductor restrictions are part of a broader strategy to bolster US technological leadership while curbing China's ability to develop advanced computing systems. Industry analysts suggest that the measures could have far-reaching implications for global supply chains and the competitive dynamics of the semiconductor market.

As the US administration's tenure nears its end, the timing of these measures is critical. President-elect Donald Trump is set to take office soon, and China reportedly views his return as an opportunity to renegotiate trade terms or exploit potential policy shifts. However, the Trump administration has yet to signal a softer stance on technology exports to China.

In conclusion, China's investigation into US subsidies for mature node chips is a new front in the ongoing chip war between the US and China. The potential consequences of this investigation could significantly impact the global semiconductor market, supply chains, and the competitive dynamics between US and Chinese chipmakers. Companies and governments alike must navigate these shifting political headwinds to maintain their competitive edge in the industry.
