Japan's trade ministry is dealing with a Chinese trade action that lands directly on a semiconductor supply chain input. Japan's minister of economy, trade and industry told reporters on September 8 that China's government made a preliminary decision on Monday, September 7, to impose provisional anti-dumping tariffs of up to 99.2% on Japanese companies caught up in its investigation into dichlorosilane.
A gas that feeds chip fabs
Dichlorosilane is a raw gas used in semiconductor manufacturing; applying heat to it forms a silicon insulating film on chips, the minister said. China's commerce ministry investigation targets Japanese producers of the material with a preliminary duty, not a final ruling. The minister said Tokyo will work closely with the Japanese companies under investigation, examine the scope and impact of the case in detail, and respond so that their business activities are not unfairly affected.
The minister connected the tariff case to a separate grievance: Chinese export controls on dual-use items that, he said, target Japan alone. He called that approach inconsistent with the international norm of not directing export controls at specific countries or groups, and said Japan has formally protested and asked Beijing to withdraw the measure. He said Japan will keep strengthening coordination with the G7 and other like-minded governments while working closely with Japanese companies on China's export restrictions.
The investment initiative's one-year scorecard
The minister also gave a status report on the US-Japan strategic investment initiative, a year after the two governments signed their memorandum of understanding. Six projects have been announced under the framework so far, and the initiative has reached roughly 20% of the $550 billion commitment, the minister said. One of those, a gas-fired power plant construction project announced in the initiative's second batch, has secured the participation of a US bank, which he said eases foreign-currency procurement for the project. He said he shared that development with the US commerce secretary during meetings last week.
The minister laid out the tests that any future project must clear before Tokyo lets it proceed. Under the MOU, project selection requires confirmed cost recovery and repayment certainty, meaning no large losses, and demonstrated benefit to Japanese companies, which he said can include direct profit or a project that opens future business opportunities even where near-term margins are thin. Those two conditions are checked through a joint Japan-US consultation committee, and the minister said a project does not move forward if the committee cannot confirm them. He declined to preview which specific deals might come next, saying only that officials continue watching developments in AI, semiconductors and other economically sensitive sectors while pursuing projects that serve mutual benefit and economic security under the two countries' self-described special partnership.
The two threads sit side by side on the minister's desk this week: a Chinese tariff decision aimed at a narrow but essential chip-fab input, and a slower-moving US investment framework that Tokyo insists must clear profitability and domestic-benefit tests before any project counts toward the next 80% of its $550 billion target.
