"There will be language in our joint statement which reaffirms and underscores our commitment to peace and stability across the Taiwan Strait," the official said ahead of the summit.

He noted that the three sides pledged to establish a trilateral hotline to discuss possible crises in the time of uncertainty but declined to say if they would use this line to talk about a possible Chinese attack on Taiwan.

"The discussions that are undertaken between the three countries involve the security situations in the broader Indo-Pacific region," the official added.

The US-South Korea-Japan summit on Friday will be the first time the leaders of the three countries have met outside of a multilateral event. US President Joe Biden will host South Korean President Yoon Suk-yeol and Japanese leader Fumio Kishida at Camp David, the US presidential retreat located about 60 miles from Washington, D.C.
