Japan's Prime Minister Shigeru Ishiba said Sunday that his government will not include discussions on security in its trade talks with the United States, while US President Donald Trump has called for reducing the US burden in defending Japan."I don't think it is appropriate to discuss security and trade together. We should address security issues without linking them to tariffs," Ishiba said on a TV program, days after his close aide met with Trump and senior US officials on the recently increased levies.Ishiba also said he believes that cutting the US trade deficit with other countries is Trump's top priority, pledging to review Japan's automobile regulations to move forward negotiations with the United States."We will work hard to ensure that Japan is not accused of being unfair," Ishiba said, but he did not elaborate on other key issues such as foreign exchange rates and Tokyo's holdings of US Treasurys, according to Kyodo News Agency.On when to conclude the talks, Ishiba said, "They must produce a desirable outcome for both sides. We want to take the necessary time to create a model for the world."Ishiba, meanwhile, said Japan, as a leader in free trade, will bolster cooperation with the Association of Southeast Asian Nations and the European Union, while expressing concern over the negative impact of the U.S.-China tit-for-tat tariff escalation.Last Wednesday, economic revitalization minister Ryosei Akazawa, Japan's chief negotiator for tariff talks with the United States, met in Washington with Treasury Secretary Scott Bessent, Commerce Secretary Howard Lutnick and US Trade Representative Jamieson Greer.
