The relationship between the European Union (EU) and South Korea is primarily based on economic and trade ties, but also includes cooperation in areas such as security, human rights, and regional stability.
Regarding the issue of arming Ukraine, the EU has been calling on its partners, including South Korea, to refrain from selling arms to Russia, which is involved in the ongoing conflict in eastern Ukraine. The EU has imposed sanctions on Russia over its annexation of Crimea in 2014 and its support for separatist rebels in eastern Ukraine.
The EU has been pressing South Korea to join the international community in imposing sanctions on Russia and to support efforts to find a peaceful solution to the conflict. The EU has also been urging South Korea to limit its military cooperation with Russia and to avoid selling arms to Russia or to other countries involved in the conflict.
While South Korea has not been directly involved in the conflict in Ukraine, it is a significant arms exporter and has been supplying weapons to other countries in the region. The EU has been concerned that these weapons could be used to fuel the conflict in Ukraine and has been calling on South Korea to be more cautious in its arms exports.
Overall, the EU-South Korea relationship is multifaceted and includes cooperation on a wide range of issues. The issue of arming Ukraine is just one of the many topics that the two sides are discussing
