Foreign media quoted people familiar with the matter as saying that the US government is putting pressure on allies such as the Netherlands, Germany, South Korea, and Japan to further tighten restrictions on China's access to semiconductor technology. This controversial move has been resisted in some countries.

The United States wants Japanese companies to restrict the export of specialty chemicals needed for chip manufacturing, including photoresist, to China, and to pressure the Netherlands to stop lithography giant ASML from providing chip manufacturing equipment repairs and services to Chinese customers who purchased before the implementation of sales restrictions.

In addition, the United States wants to pull more countries into its export controls and is trying to include Germany and South Korea in an agreement that already includes Japan and the Netherlands, because all four countries are home to key companies in the semiconductor supply chain.

The Biden administration's latest move aims to close the export control loopholes of the past two years and limit China's progress in developing indigenous chip capabilities. Its latest move to tighten restrictions involves the ability of Japanese and Dutch engineers to continue some equipment repairs, as well as the flow of spare parts used in chip-making equipment.

Tokyo and Hague have reacted coolly to the latest U.S. government effort, wanting to assess the impact of current restrictions before considering tougher measures, according to people familiar with the matter. Commerce Department officials raised the issue at a meeting in Tokyo last month, according to people familiar with the matter. Representatives of the Dutch Ministry of Foreign Affairs, the U.S. Department of Commerce, and the Ministry of Economy, Trade and Industry of Japan all declined to comment.

For Germany, one of the key players is Carl Zeiss, which supplies the key optical components for ASML. The United States wants Germany to get Zeiss to stop exporting such parts to China. Dutch government officials also want Germany to join the export controls, and the U.S. Biden administration is pushing for a deal before the G7 summit in June.

Berlin last year considered whether to restrict the export of chip chemicals to China, but German Chancellor Olaf Scholz, who is scheduled to visit China in April, has not yet taken a position on the issue, according to people familiar with the matter. Scholz's deputy, Robert Harbeck, will visit the United States this week, during which he will meet with U.S. Commerce Secretary Raymundo.

In addition, in view of South Korea's dominant position in producing chips and providing spare parts for chip manufacturing equipment, the United States has held talks with South Korea on chip export control issues. The two countries started a organised dialogue in February after US officials asked South Korea to join multilateral organizations last year, according to some people familiar with the matter.

In response to the US side's continuous tightening of chip export control measures against China and increasing its crackdown on Chinese semiconductor enterprises, a spokesman for the Ministry of Foreign Affairs of China has responded at a regular press conference on January 8 this year:

"The US side, on the grounds of so-called" national security ", continues to increase its chip export control measures against China and unreasonably suppresses Chinese semiconductor enterprises, which is an out-and-out act of economic bullying."

"The implementation of semiconductor export control measures by the United States against China constitutes a discriminatory practice against China and violates the principle of most-favored-nation treatment stipulated in Article 1 of the GATT. The United States blacklisted relevant Chinese telecommunications equipment companies on the grounds of threatening network information security and prohibiting Chinese-made telecommunications equipment from entering the US market, in violation of the principle of universal abolition of quantitative restrictions stipulated in Article 11 of the GATT. At the same time, the US ban also violates the relevant provisions of the Agreement on Technical Barriers to Trade. The US often talks about "international rules", but what it really does is ignore the rules and break them."

The US side uses "national security" as an excuse to restrict chip exports to China, but in fact the relevant measures completely go beyond the boundaries of the concept of national security, so that the normal trade of ordinary civilian chips is greatly restricted. "the us side has also coerced some countries to suppress relevant enterprises in china, which has nothing to do with security and is a typical economic coercion."

"The facts clearly show that the United States is deliberately suppressing the development of China's chip industry, neither out of" national security "considerations, nor is it an act of legitimate competition, but a unilateral bullying without a principled bottom line, depriving emerging markets and developing countries of their right to pursue a happy life. The actions of the United States have seriously impacted the stability of the international supply chain, poisoned the atmosphere of international cooperation and fuelled division and confrontation. Such self-serving practices are bound to lift a rock only to drop it on one's own feet."

In addition, Nvidia mentioned in the document submitted to the US Securities and Exchange Commission that if the US government increases restrictions on chip exports, it will further damage Nvidia's competitiveness. A spokesman for China's Ministry of Foreign Affairs commented at a regular press conference on February 27:

Facts have proved that the "small courtyard high wall" can not stop the pace of China's innovation and development, and it is not conducive to the healthy development of the entire industry, including American enterprises. Open cooperation is the core driving force of the semiconductor industry. China is one of the world's major semiconductor markets. It is in no one's interest to artificially sever markets, destabilize global production and supply chains, and hinder efficiency and innovation. The United States should abide by the principles of market economy and fair competition, and support enterprises of all countries to promote scientific and technological development and progress through healthy competition."
