Japan, South Korea and the United States are looking to establish a hotline for urgent communications, following a trilateral leaders summit in Washington set for Friday, according to a senior U.S. official.

“We're going to invest in technology to have a three-way hotline for the leaders and others inside their governments to communicate,” White House Indo-Pacific Coordinator Kurt Campbell said during an event at a Washington think tank on Wednesday.

Prime Minister Fumio Kishida departed for Washington on Thursday for the first standalone trilateral summit with U.S. President Joe Biden and South Korean leader Yoon Suk-yeol the following day at the Camp David presidential retreat in Maryland, where the three are expected to agree on a “very ambitious set of initiatives that seek to lock in trilateral engagement,” according to Campbell.
