In recent years, the US has repeatedly used national security as a pretext to impose export controls, seriously harming the legitimate rights of Chinese companies, disrupting international trade, and destabilizing the global semiconductor supply chain, Chinese Commerce Ministry Spokesperson He Yongqian said on Thursday.

The sharp remarks followed a move by the US Department of Commerce on Sunday that was aimed at closing a purported mechanism that allowed Chinese firms' overseas subsidiaries to access advanced microchips, including Nvidia's cutting-edge Blackwell processors, as part of its ongoing effort to limit China's access to semiconductors needed to develop advanced AI capabilities.

The ministry also opposed a recent OECD report on industrial subsidies to Chinese companies.

China's industrial subsidy policies fully comply with World Trade Organization rules and transparency obligations, the spokesperson said, stating that the OECD report is flawed, with vague definitions, biased sample selection, and one-sided conclusions. According to the ministry, the report lacks a consistent methodology or standards for measuring "subsidies" and ignores WTO and other multilateral frameworks.

The ministry further emphasized that the report wrongly attributes Chinese companies' growing global market share solely to government support, overlooking their real competitive advantages—such as economies of scale, production efficiency, and technological innovation.
