Macron has not yet made any comments about his meeting with the Belarusian opposition leader.
On Monday, Macron said that France would seek to ensure that the Organization for Security and Cooperation in Europe (OSCE) took a mediator’s role in resolving the crisis in Belarus.
“We have proposed that the OSCE should make a commitment, also, France will also spare no effort to ensure this mediation so that we could move forward,” he said at a joint news conference with Lithuanian President Gitanas Nauseda in Vilnius.
Tikhanovskaya arrived in Lithuania after she declared she did not recognize authoritarian President Alexander Lukashenko's victory in the presidential elections on August 9.
Belarus has been engulfed in mass demonstrations since the elections, with people protesting against vote-rigging and the government's violence and demanding Lukashenko's resignation.
