The Russian government on Monday said that President Trump and Russian President Vladimir Putin are still expected to meet on the sidelines of the upcoming Group of 20 (G-20) summit despite the flaring crisis in Ukraine.

“This meeting is being prepared,” Kremlin spokesman Dmitry Peskov told reporters when asked if the tensions with Ukraine would impact the planned meeting, according to Russia’s state-owned TASS news agency. The White House did not immediately return a request for comment on whether the meeting is still expected to take place.

{mosads}Relations between Moscow and Kiev deteriorated sharply in the last 24 hours after Russia opened fire and seized three Ukrainian ships sailing through the Kerch Strait off the coast of the Crimea Peninsula, which Russia annexed in 2014.

The United Nations Security Council called an emergency meeting on the events for Monday morning. 

Ukraine, as well as the majority of the international community, including the U.S., do not recognize Russia’s annexation of Crimea as legitimate.

Trump will travel to Argentina later this week to participate in the G-20 summit, where he is also expected to have a high-stakes meeting on trade with Chinese President Xi Jinping. Trump revealed in early November that he would meet with Putin in Buenos Aires. Their conversation is likely to cover various topics, including the United States’s recent decision to withdraw from a decades-old nuclear arms pact with Moscow.

It will be their second face-to-face encounter since the controversial Helsinki summit over the summer, after which Trump was roundly criticized for his friendliness toward Putin and for casting doubt on the U.S. intelligence community’s assessment that Russia interfered in the 2016 presidential election. 

Trump and Putin met briefly during the Armistice Day celebrations in Paris earlier this month.
