Japan has agreed to purchase 100 Boeing aircraft and to spend an additional $8 billion on U.S. agricultural and other goods under a new bilateral investment agreement, according to a White House official. The deal will raise Japan’s annual defense procurement from American companies to about $17 billion, up from $14 billion, and boost its tariff-free imports of U.S. rice by 75%. The $8 billion commitment covers corn, soybeans, fertilizer, bioethanol and sustainable aviation fuel, the official said. Beyond near-term purchases, the accord aims to deepen cooperation in semiconductor design and manufacturing, liquefied natural gas projects and the construction of new shipyards, as Washington seeks to strengthen supply-chain ties with key allies.
