Ukraine calls on Brazil to arrest Putin if he attends G20 summit 

In an interview with Reuters, Kostin stressed that the international community must stand united and hold Putin accountable.

“Due to information that Putin may attend the G20 summit in Brazil I would like to reiterate that it's an obligation for the Brazilian authorities as a state party of the Rome Statute to arrest him if he dares to visit," Kostin said.

He also noted that if Putin is arrested, Brazil would reaffirm its status as a democracy and a state governed by the rule of law. However, Ukraine's Prosecutor General warned that if Brazilian authorities do not act on the arrest warrant, it risks setting a precedent under which leaders accused of crimes can travel with impunity.

Unnamed Brazilian officials told Reuters that Brazil sent Putin a standard invitation for the Nov. 18-19 meetings in Rio de Janeiro of the G20 group but has received no indication he planned to attend.

When asked if the Kremlin leader has decided to go to the summit, his spokesperson, Dmitry Peskov, told reporters on Monday: "No. When a decision is made, we will let you know."

Details of Putin's visit to Mongolia

On August 30, the Kremlin press service announced that Putin was to visit Mongolia on September 3 at the invitation of President Ukhnaagiin Khürelsükh. Putin's trip to Mongolia was his first visit to a country that has ratified the Rome Statute. At the same time, his spokesman Dmitry Peskov said that the Kremlin was not afraid of the Russian leader's arrest.

On the same day, the Ukrainian Foreign Ministry called on the Mongolian authorities to arrest Putin and hand him over to the International Criminal Court in The Hague.

The International Criminal Court stated that the Mongolian authorities, in accordance with their obligations, should arrest Vladimir Putin if he visits the country.

In addition, Human Rights Watch called on Mongolia to arrest Vladimir Putin. On Monday, September 2, Putin arrived in Mongolia. 

Later, it was reported that Mongolia has not arrested Russian dictator Vladimir Putin because it is dependent on Russian energy imports.
