An alliance between the United States and Japan to ban exports of sensitive technology to China risks upending trade ties between Beijing and Tokyo and would be “complex” to implement, analysts say, as the global battle for tech supremacy intensifies.

Japan and the US are mulling the establishment of a multilateral framework to regulate the trade of advanced technology, which includes semiconductor manufacturing equipment, quantum cryptography and artificial intelligence, according to a report by Japan’s Yomiuri newspaper earlier this month, citing unidentified sources.

The two countries are also planning to work with allies in Europe on the issue amid heightened concern about Beijing’s military-civil fusion strategy.

Lu Xiang, a research fellow in US studies at the Chinese Academy of Social Sciences, said it was difficult to know what form the restrictions might take, but discussions between the US, Europe and Japan would be a certainty this year.

“I wouldn’t be surprised if they are making a huge amount of effort on how to [coordinate] export control, but in reality, it’s very complex because their own companies could see limitations and losses,” Lu said.
