Ukrainian Foreign Minister Dymtro Kuleba said on Wednesday he had spoken with his South Korean counterpart about South Korea’s plan to participate in sanction against Russia, according to Reuters.

“The Republic of Korea strongly condemns Russian aggression against Ukraine and plans to take active part in sanctions pressure on Russia,” Kuleba said on Twitter.

Some Russians, in the meantime, say that it’s not so much the sanctions that worry them, but the deadly attack Russia waged on a neighboring country.

“You know, sanctions bother me the least. I’m worried about Russia killing people in Ukraine,” said Moscow resident Ivan Kozlov. “I wish it stopped the war no sane person with a conscience and capable of mercy and compassion in Russia wants.”

Anti-war sentiment in Russia has been widespread. Thousands of people have signed open letters and online petitions demanding to stop the invasion, with the most widely supported online petition garnering over 1 million signatures in several days.

Russians across the country have been taking to the streets almost every day since the attack started last Thursday. More than 7,000 protesters have been detained in the past week, according to OVD-Info, rights group that tracks political arrests, with nearly 600 arrests taking place on Wednesday.
