Ukraine violated South Korea's diplomatic trust by disclosing the transfer of the North Korean prisoners

Ukraine's foreign minister said Kyiv was working to resolve the disagreement over its public disclosure of two North Korean prisoners' transfer to South Korea. On 2 October, President Lee Jae Myung threatened further measures unless Ukraine acknowledged what Seoul says was a confidentiality agreement and apologised, and Seoul has since announced a further reduction in its Kyiv embassy staffing. Essential diplomatic personnel remained, so this is reduced staffing rather than a complete embassy closure. Kyiv disputes that such an agreement existed, and the two governments give conflicting accounts of whether confidentiality had been agreed.
