Japan's Prime Minister Shigeru Ishiba said Friday that he held telephone talks with U.S. President Donald Trump and agreed to hold "productive" discussions at an upcoming tariff talks between the two sides.

"Investment, not tariffs," Ishiba told reporters after the talks. He said Japan's position to keep pushing Washington to drop all recent tariff measures is unchanged and that he stands by plans to push for Japanese investment to create more jobs in the U.S. in exchange.
