Trump arrives in Japan seeking to end China trade war, meet Kim Jong-un
Trump is also due in South Korea for the Asia-Pacific Economic Cooperation (APEC) summit and will meet President Lee Jae-myung.
Optimism has grown that Donald Trump and China's Xi Jinping will end their bruising trade war in talks this week, as the US president touched down in Tokyo on the latest leg of an Asian tour.
Trump said on Monday, en route to close US ally Japan, that he was hopeful of a deal when he meets with Xi on Thursday, while also indicating he was willing to extend his trip to meet North Korean leader Kim Jong-un.
"I have a lot of respect for President Xi, and we are going to, I think, come away with a deal," Trump told reporters on Air Force One, adding that he aimed to go to China "in the earlier part" of 2026.
"A great man," Trump said afterwards.
The optimism boosted stock markets, with Japan's Nikkei surpassing 50,000 points for the first time.
On Tuesday, Trump was expected to meet new Prime Minister Sanae Takaichi and make a speech on the USS George Washington aircraft carrier, docked at the US naval base Yokosuka.
"I hear phenomenal things. (Takaichi) was a great ally and friend of Shinzo Abe, who was my friend," Trump said, referring to the assassinated former premier.
Japan trade deal
On Friday, Takaichi announced in her first policy speech that Japan would be spending two percent of gross domestic product on defence this fiscal year.
But Washington, which has around 60,000 military personnel in Japan, wants Tokyo to spend more, potentially matching the five percent of GDP pledged by NATO members in June.
Most Japanese imports into the United States are subject to tariffs of 15 percent, less painful than the 25 percent first threatened.
However, Trump also wants Japan to import more American products like rice, soybeans and cars, including "hot" Ford F-150 pickup trucks.
Questions also surround Japan's commitment to invest $550 billion in the United States, as specified in its July trade deal.
"What I expect is that, since he (Trump) is someone who acts decisively, things might move in a positive direction for Japan," said Tokyo resident Sayaka Kamimoto, 45.
Kim Jong-un meeting?
Trump is due in South Korea on Wednesday for the Asia-Pacific Economic Cooperation (APEC) summit and will meet President Lee Jae-myung.
Trump has also fuelled speculation that he could hold face-to-face talks with North Korea's Kim while on the Korean peninsula.
The two leaders last met in 2019 at the Demilitarised Zone (DMZ), the border area separating the two Koreas.
"I would love to meet with him if he'd like to meet. I got along great with Kim Jong-un. I liked him. He liked me," Trump said on Air Force One.
Asked if he would extend his trip to enable a meeting, he said, "Well, I hadn't thought of it, but I think the answer would be yeah, I would; I would do that, sure."
