On Monday, the Russian president made his first visit to an ICC member country since the court issued an arrest warrant for him almost eighteen months ago, on charges that he had committed war crimes in Ukraine.
On Tuesday, Mr. Putin is expected to meet Ukhnaa Khurelsukh, the leader of Mongolia.
“Mongolia has permitted an accused criminal to avoid prosecution, consequently bearing some of the blame for the war crimes,” Heorhiy Tykhyi, a spokesman for the Ukrainian foreign ministry, wrote on Telegram.
He said that the nation will cooperate with its partners to make sure Mongolia suffered the consequences.
While the Kremlin stated last week that it was unconcerned about the visit, Ukraine wants Mongolia to detain Mr. Putin and turn him over to the court in The Hague, the Netherlands.
Although the court cannot enforce the regulation, ICC members are required to hold individuals if an arrest warrant has been issued.
Mongolia, a vast, sparsely populated nation between China and Russia, is mostly dependent on Beijing for mining industry investment and on Moscow for gasoline and energy.
