Days after U.S. President Donald Trump announced a ¡°partnership¡± between Nippon Steel and United States Steel, the Japanese steelmaker remains unsure about what that really means, while the Japanese government isn¡¯t filling in the gaps.

On Sunday, the U.S. president provided additional information about the transaction, which he first mentioned in a Friday social media post. His Sunday comments also further muddied the waters.

¡°It will be controlled by the United States, otherwise I wouldn¡¯t make the deal,¡± Trump said of U.S. Steel post-transaction. ¡°They¡¯re going to invest millions of dollars in steel. It¡¯s an investment, and it¡¯s a partial ownership. But it¡¯ll be controlled by the USA.¡±
