By David Brunnstrom, Simon Lewis, Trevor Hunnicutt and Tim Kelly TOKYO/WASHINGTON (Reuters) -The foreign ministers of Japan and the United States said their countries' ties were stronger than ever on Tuesday,

Japan's prime minister on Monday urged Washington to dispel concerns that a decision by Joe Biden to block Nippon Steel's takeover of US Steel could impact future investments. Prime Minister Shigeru Ishiba said the veteran Democrat's decision had sparked worries over future Japanese investments in the world's largest economy.

US Secretary of State Antony Blinken insisted during a visit to Tokyo on Tuesday that ties with Japan were stronger than ever, days after President Joe Biden blocked Nippon Steel's takeover of US Steel.
