President Biden met with South Korea's president and Japan's new prime minister at the Asia-Pacific Economic Cooperation summit. He said cooperation with the allies is integral to countering North Korea and Russia's cooperation.

U.S. President Joe Biden met with Japanese and South Korean leaders on Friday as they sought to cement their diplomatic progress ahead of a new Trump administration that many fear could upend alliances worldwide.

Biden noted that it would be his last meeting with the two countries but that the trilateral partnership should be preserved for years to come.
