U.S. President Joe Biden will host Prime Minister Fumio Kishida and South Korean leader Yoon Suk-yeol on Aug. 18 for the first standalone trilateral summit between the three leaders, the White House has announced, with North Korea’s “continued threat” set to top the agenda.

The summit will be held at the Camp David presidential retreat in Maryland, the White House said Friday, as the three leaders look to expand trilateral cooperation “across the Indo-Pacific and beyond.”

"The summit will advance a shared trilateral vision for addressing global and regional security challenges, promoting a rules-based international order and bolstering economic prosperity," White House press secretary Karine Jean-Pierre said in a statement.

In Seoul, presidential spokesperson Lee Do-woon told the Yonhap news agency that the summit “will be an important opportunity” to elevate the cooperation among the three countries “to a new level.”

The three leaders have held joint meetings on the sidelines of international events, but have never held a formal trilateral summit.

At next month’s meeting, the three are expected to release a joint statement condemning North Korea's missile tests and nuclear saber-rattling while also calling for Pyongyang to return to long-stalled denuclearization talks.

The talks remain a nonstarter with Pyongyang, which in September passed a law that makes its nuclear status "irreversible" and bars any negotiations on relinquishing its arsenal.

The summit announcement came just days after North Korea held a massive military parade overseen by leader Kim Jong Un, who was joined by senior Chinese and Russian officials. The parade marking the 70th anniversary of the Korean War armistice included North Korea's latest Hwasong-17 and Hwasong-18 intercontinental ballistic missiles, state-run media said. The weapons are believed capable of delivering nuclear bombs to anywhere in the United States.

The North has fired off a volley of missiles this month, including the solid-fuel Hwasong-18, in defiance of U.N. Security Council resolutions that ban its possession and testing of the weapons.

Pyongyang’s unprecedented spate of more than 100 missiles tests since last year has helped push the Japan-South Korea bilateral relationship closer as they look to cooperate on security issues, including with their mutual ally, the U.S., after years of soured ties over disagreements about wartime labor and other historical issues.

Japan — which called North Korea “an increasingly serious and imminent threat" in its annual defense white paper released Friday — warned that “provocations” by the North could continue, including a potential seventh nuclear test, a possibility that only grew with the appearance of the officials from United Nations Security Council members China and Russia.

The two countries, which have been under pressure from the U.S. and its partners amid Moscow’s war in Ukraine and the growing Sino-American rivalry, had in the past sought to distance themselves from their neighbor's nuclear and missile ambitions. But the visit to Pyongyang by Russian Defense Minister Sergei Shoigu, in particular, has highlighted a shift, with Shoigu photographed viewing banned North Korean ballistic missiles with Kim at a defense expo.

Shoigu’s attendance at the Korean War anniversary celebrations has raised concerns that Russia could be looking to buy weapons from North Korea as its stockpiles dwindle amid its ongoing invasion of Ukraine.

A report Saturday in the Financial Times said Moscow appeared to have already been using North Korean rockets, with Ukrainian soldiers observed using the weapons that they said were seized by a "friendly" country before being delivered to them.

Ukraine's Defense Ministry suggested the arms were captured from the Russians, the newspaper said. North Korea and Russia deny conducting arms transactions, despite claims by the U.S. of weapons deals.
