China Semiconductor Industry Association said on Tuesday that United States' recent moves have made US chip products "less secure and reliable", forcing Chinese companies to be more cautious in purchasing US chips.

The strong statement was made in opposition to the new export restrictions imposed by the US on Monday, which are curbs on the sale of two dozen types of semiconductor-making equipment and restrictions on numerous Chinese companies from accessing US technology.

According to the association, such measures have undermined the principles of fairness, reasonableness and non-discrimination that have long guided the global semiconductor industry. The restrictions also contravened the spirit of the World Semiconductor Council charter and violated the World Trade Organization's commitment to fair trade.

"Arbitrary changes to trade rules by the US government have caused substantial harm to the security and stability of the global semiconductor supply chain," it said.

In its statement, the association warned that unilateral actions by the US are increasing costs for the global semiconductor industry and disrupting supply chains. It was noted that the restrictions are also causing problems for US companies, including supply chain interruptions and rising operational costs.

"This has made US chips less secure and reliable, compelling Chinese companies to be more cautious in purchasing US chips," it emphasized.

As China's semiconductor industry has grown and thrived through globalization, the association emphasizes its commitment to open collaboration and calls for deeper cooperation with semiconductor companies worldwide to promote the prosperity and development of the global industry.
