U.S. Secretary of State Antony Blinken held talks with his counterpart in Japan on Tuesday, as he sought to reassure a nervous Tokyo that their alliance will remain robust even after Donald Trump returns to the White House in less than two weeks.

Blinken, fresh off his visit to Seoul, met with Foreign Minister Takeshi Iwaya for an hour-and-a-half working lunch, with the two "agreeing on the importance of continuing to cooperate to further strengthen the deterrence and response capabilities of the Japan-U.S. alliance," the Foreign Ministry said in a statement.

The top U.S. diplomat later paid a courtesy visit to Prime Minister Shigeru Ishiba.
