Japan Ramps Up Chip Export Controls Amid Rising US-China Tech Tensions

Japan is stepping up its control on the export of sophisticated technology including advanced processors, quantum computing cryocoolers, and lithography equipment, aiming to limit their potential military use. According to a report from The Japan Times, starting in May, businesses will need to secure export licenses to sell these high-tech items abroad. The Japanese government has also placed 42 Chinese entities on a trade restriction list, a move that has sparked criticism from China over possible disruptions to global trade.

The updated export regulations cover technology like cryogenic cooling systems crucial for quantum computers and processors that could potentially be utilized in missile guidance systems. Japanese officials have clarified that the intent of these measures is to prevent military applications rather than to target any particular nations. These steps are in line with concerns expressed by the U.S. about the re-export of high-performance Nvidia GPUs for AI applications to China, though it is not specifically mentioned that Japan will restrict Nvidia GPU re-exports to other countries.

Furthermore, Japan has increased the roster of international entities subject to its export controls. The Ministry of Economy, Trade and Industry has added 42 more entities, bringing the total of Chinese companies, research institutions, and other organizations under Japanese export scrutiny to approximately 110. This expanded list will come into effect on February 5.

China has strongly protested these new restrictions, claiming they could interrupt the international supply chains and affect business operations negatively. The Chinese Ministry of Commerce has called on Japan to protect the economic relationship between the two countries from adverse impacts.

Amid these tensions, China has been actively trying to bolster its diplomatic relations with allies of the U.S., including Japan. Chinese Foreign Minister Wang Yi recently extended an informal invitation to Japanese Prime Minister Shigeru Ishiba to attend the opening of the Asian Winter Games in Harbin in early February. However, Japanese officials have indicated that Ishiba’s attendance is unlikely because of conflicting schedules.

Instead, Prime Minister Ishiba is scheduled to meet with U.S. President Donald Trump on February 7, prioritizing U.S. relations over a potential visit to China. Diplomatic engagements continue, however, as Japan’s Foreign Minister Takeshi Iwaya recently met with both Foreign Minister Wang Yi and Premier Li Qiang in Beijing. The discussions aimed to enhance tourism and keep security communication channels open.

Despite the heightened trade controls, Japanese technology firms still saw a surge in demand last year for semiconductor manufacturing equipment from Chinese companies, with sales hitting record levels. Nevertheless, the long-term effects of these new export restrictions on Japan’s tech industry are yet uncertain, as companies evaluate the implications of potentially losing a significant market.
