President Joe Biden is expected to use his final meeting with China’s President Xi Jinping to urge him to dissuade North Korea from further deepening its backing of Russia’s war on Ukraine.

The president said stronger ties with South Korea and Japan are working, but did not address whether President-elect Donald J. Trump would continue his approach when he takes office in January.

US President Joe Biden told the leaders of Japan and South Korea that their coordinated efforts were essential to “countering North Korea’s dangerous and destabilizing cooperation with Russia” as they met Friday on the sidelines of the APEC Summit in Lima.

German Chancellor Olaf Scholz told Russian President Vladimir Putin on Friday that Russia’s deployment of North Korean troops against Ukraine was a “grave escalation” of the conflict, according to government sources.

Captured Russian soldiers have revealed the presence of North Korean troops fighting in Ukraine under Vladimir Putin’s command. The prisoners of war (POWs) shared these details during interrogations by Ukrainian forces.
