SEOUL, South Korea (AP) — Japan’s outgoing prime minister and his South Korean counterpart underscored the need to strengthen cooperation between their nations, as U.S. President Donald Trump’s transactional approach to allies and trade wars are bringing the often-feuding Asian neighbors closer. Tuesday’s meeting between Japanese Prime Minister Shigeru Ishiba and South Korean President Lee Jae Myung in the South Korean southeastern port city of Busan is their third and likely final summit. South Korea and Japan are both key U.S. allies and major trading partners. South Korea and Japan have sought ways to tackle together challenges like North Korea’s expanding nuclear arsenal and supply chain vulnerabilities. South Korea and Japan have pledged hundreds of billions of dollars in U.S. industrial investments in hopes of avoiding the Trump administration’s highest tariffs.
