According to online reports, according to the British "Financial Times", the United States and Japan have obvious differences in their interpretation of the details of the previously reached agreement. Tokyo said on Friday that if the United States wants to obtain 90% of joint investment profits, it assumes a corresponding proportion of risk and financing responsibilities. Earlier, U.S. Commerce Secretary Lutnik announced that under the framework of the latest tariff agreement, Japan will fund and support the US$550 billion investment in U.S. strategic industries, and the United States will receive 90% of the profits. But a slide released by Japan's Cabinet Office on Friday made it clear that the profit distribution "will be determined based on the degree of contribution and risk taken by all parties." Japanese officials pointed out that Japan and the United States have not reached any written agreement on the investment, nor have they signed a legally binding agreement. According to people familiar with the matter, the agreement was hastily reached during a 70-minute meeting between Japan's chief negotiator, Ryoshi Akasawa, and the United States on Tuesday. The Trump team is worried that if Japanese Prime Minister Shigeru Ishiba steps down due to political instability, he will have to renegotiate, so they are eager to finalize the agreement.
