South Korea’s president said his government “won’t sit idle” as North Korea allegedly sends troops to support Russia’s war on Ukraine, as he met with the leader of Poland to discuss expanding defence cooperation amid the ongoing conflict.

The meeting between South Korean President Yoon Suk Yeol and Polish President Andrzej Duda came a day after US and South Korean officials said they believe around 3,000 North Korean troops have been deployed to Russia and are training at several locations.
