President Donald Trump begins a busy day in Asia on Tuesday, meeting Japan's new prime minister and speaking to U.S. troops. Sanae Takaichi became Japan's first female prime minister just days ago and aims to strengthen ties with Trump while defending Japan's economic interests. Trump seeks $550 billion in Japanese investment to reduce U.S. tariffs. He arrived in Tokyo on Monday after attending a summit in Malaysia. There, he celebrated a ceasefire agreement between Thailand and Cambodia. Meanwhile, tensions between the U.S. and China appear to be cooling, with a trade deal possibly in the works. Trump plans to leave for South Korea on Wednesday.
