The meeting, on the sidelines of a summit of Group of Seven (G7) leaders in the Japanese city of Hiroshima, marks the first time the two leaders have met.

“Thanked (Yoon) for the humanitarian and non-lethal assistance to Ukraine, in particular, for demining vehicles. I look forward to continued cooperation,” Zelensky tweeted.

Yoon was briefed on the situation at the front and how Ukraine is repelling Russia’s “full-scale aggression,”  said of Moscow’s 15-month invasion of his country.

The Yoon-Zelensky meeting was arranged at Ukraine’s request, South Korean news agency Yonhap reported, citing Yoon’s office. The two countries agreed to exchange visits of delegations, Zelensky’s office said in a statement.

Last week, Ukrainian first lady Olena Zelenska visited South Korea to attend a media conference. She met with Yoon and asked for non-lethal military assistance for her country, according to South Korea’s presidential office.

A day after that request, Seoul announced an agreement with Ukraine on a plan to provide US$130 million in financial aid.

South Korea, a major producer of artillery shells, has said it was not providing lethal weapons to Ukraine, citing its relations with Russia.

But in an interview with Reuters last month, Yoon said his government might not “insist only on humanitarian or financial support” if civilians in Ukraine come under a large-scale attack or because of a “situation the international community cannot condone”.
