WASHINGTON (Kyodo) -- The leaders of the United States, Japan and South Korea will hold a trilateral summit in Peru on Friday, the U.S. government said, with North Korea's missile and nuclear developments and other security challenges likely on their agenda.

Outgoing U.S. President Joe Biden and his Japanese and South Korean counterparts, Shigeru Ishiba and Yoon Suk Yeol, will meet on the sidelines of the Asia-Pacific Economic Cooperation forum's two-day summit through Saturday in Lima, the White House said Wednesday.

The leaders are expected to reaffirm the three nations' security collaboration, which has been strengthened since Biden took office in 2021, ahead of the inauguration next January of U.S. President-elect Donald Trump, known for his "America First" doctrine.

White House National Security Adviser Jake Sullivan told a press briefing that the three will gather "to celebrate the historic cooperation between our three nations and discuss the importance of institutionalizing the progress we've made so that it carries forward through the transition."

In recent years, the United States and its two East Asian allies have been boosting their readiness against threats from North Korea, which has been repeatedly test-firing ballistic missiles with fears lingering over a seventh nuclear test, the first since 2017.

North Korea has also been increasing military collaboration with Russia, recently dispatching soldiers to help Moscow's full-scale invasion of Ukraine.
