 South Korean President Yoon Suk Yeol visited Ukraine on July 15 for talks with President Volodymyr Zelensky, the South Korean presidential office said. The surprise trip came after Yoon attended a NATO summit in Lithuania and visited Poland this week, where he expressed solidarity with Ukraine and explored ways to support its fight against Russia's invasion. Yoon visited the site of mass killings in Bucha near the capital Kiev, before visiting Erpen, a residential area that received large-scale missile attacks. He was expected to hold a summit with Zelensky afterward, his office said. A US ally and rising arms exporter, South Korea has faced renewed pressure to provide weapons to Ukraine, which Yoon's administration has resisted in favor of humanitarian and financial aid, wary of Russia's influence over North Korea.
