Visiting U.S. Vice President Mike Pence on Tuesday declared his country's "unwavering commitment" to Japan as it looks to confront the "ominous threat" posed to the region by the North Korean regime.

Speaking after a meeting with Prime Minister Shinzo Abe in Tokyo, Pence said, "The alliance between the United States and Japan is the cornerstone of peace and security in northeast Asia."

"We appreciate the challenging times in which the people of Japan live with increasing provocations from across the Sea of Japan," Pence told reporters at the Prime Minister's Office.
