Oct. 28 (UPI) -- President Donald Trump met with Japan's first female prime minister Tuesday in Tokyo to mark "a new golden age of the Japan-U.S. alliance," before signing a deal on trade and a second agreement on critical minerals.

Prime Minister Sanae Takaichi, who was elected prime minister just last week, pledged to build a "new golden era," calling the bilateral relationship "the greatest alliance in the world." Takaichi also praised Trump for his role in securing global cease-fires.

"Mr. President succeeded in securing a cease-fire deal between Thailand and Cambodia ... also, the deal you have recently achieved in the Middle East is an unprecedented, historic achievement," Takaichi said during Tuesday's meeting.

Trump told Takaichi that she would be "one of the great prime ministers," while praising Japan as "a great ally."

"I want to just let you know, any time you have any question, any doubt, anything you want, any favors you need, anything I can do to help Japan, we will be there," Trump said. "This will be a relationship that will be stronger than any before and I look forward to working with you and on behalf of our country."
