“We discussed the major geopolitical crises, including Ukraine, and we had the opportunity to raise this directly with Sergei Lavrov,” Kallas said, according to AFP.
“Of course, he made some false claims and told some lies, which we were able to refute.”
Russia's Foreign Ministry has previously said that Lavrov would use the meeting to argue against international sanctions on the country.
The G20 meeting, which began on Friday and continues on Saturday, is intended to lay the groundwork for the G20 meeting in Miami in December, hosted by President Donald Trump.
