China is banning REM exports to curb US tech development

SINGAPORE—China set export restrictions on two minerals the U.S. says are critical to the production of semiconductors, missile systems and solar cells, a show of force ahead of economic talks between two rivals that increasingly set trade rules to achieve technological dominance.

The minerals—gallium and germanium—and more than three dozen related metals and other materials will be subject to unspecified export controls starting Aug. 1, Beijing’s Ministry of Commerce said Monday. Its statement referred to safeguarding national security and interests and said some future export applications would require review by the government’s top body, the State Council.

The China-U.S. rivalry increasingly features export restrictions tailored to slow the high-technology industries of the other nation. Trading complaints about such controls, which both sides say are designed to protect national security, have featured in a return to high-level talks between the two governments. More focus on the issue is likely when Treasury Secretary Janet Yellen visits Beijing later this week and if Commerce Secretary Gina Raimondo makes an expected trip in the coming months.

The U.S. Commerce Department had no immediate comment.

The U.S. in October halted exports to China of equipment used to produce more technically advanced semiconductors and has leaned on allies like South Korea and the Netherlands to do the same. Beijing warned its companies to consider the national-security implications of exports to the U.S. It banned the use of products made by Micron, the U.S.’s biggest memory-chip maker, in its critical information-infrastructure firms, while warning American allies to reject what it terms Cold War-type protectionism peddled by Washington.

Complexities bind the U.S. and China in production of wares such as semiconductors in ways that make it difficult for either side to act too rashly, a kind of technology-sector equivalent of mutually assured destruction. The Biden administration is trying to entice producers such as Samsung and Taiwan Semiconductor Manufacturing Co. to expand in the U.S. but getting them to turn their back on China appears unlikely.

The new restrictions on gallium and germanium affect specialty metals produced and refined primarily in China, giving it leverage in some cutting-edge sectors. Neither gallium or germanium is traded in large quantities. Both nevertheless have uses important to particular industries, especially production of semiconductors that are often designed in and for use in the U.S. even if made in Taiwan and South Korea.

“This measure will have an immediate ripple effect on the semiconductor industry, especially with regards to high-performance chips,” said Alastair Neill, board member of the Critical Mineral Institute who has nearly 30 years of experience with China’s metals industry.

China has smarted at U.S. efforts to slow the advance of its semiconductor manufacturing, which Washington warns is ultimately aimed at strengthening Beijing’s military. The Biden administration has made it difficult for China to buy lithography machines needed to produce high-performance chips, and last week scored a win when the Dutch government said its equipment makers like ASML would need government permission to ship some products abroad.

Chinese chip makers and suppliers who gathered in Shanghai for a recent industry event were in a grim but defiant mood following a Wall Street Journal report that the Biden administration is considering new restrictions on exports of artificial-intelligence chips to China.

Industry analysts see a pattern of tit-for-tat. “If you don’t send high-end chips to China, China will respond by not sending you the high-performance elements you need for those chips,” said Neill, who added that Beijing usually tries to match U.S. trade measures with a countermeasure of equal proportion.

Both gallium and germanium appear among 50 minerals that the U.S. Geological Survey deems “critical,” meaning they are essential to the economic or national security of the U.S. and have a supply chain vulnerable to disruption.
