Russia said on Wednesday it still expects a meeting between President Vladimir Putin and President Donald Trump to go ahead as planned.
Trump, in an interview with The Washington Post on Tuesday, said he may cancel the sit-down with Putin in Argentina following Russia's seizure of three Ukrainian naval ships last weekend.
Kremlin spokesman Dmitry Peskov told reporters on Wednesday that the meeting is on and that Russia has not received "any other information from our US counterparts."
"Maybe I won't have the meeting," he said. "Maybe I won't even have the meeting." Trump added: "I don't like that aggression. I don't want that aggression at all."
White House spokeswoman Sarah Huckabee Sanders called the trip an opportunity for the president to cement relations with other world leaders and advance a global economic system based on "free, fair and reciprocal trade."
He said Trump is "not going away."
