On Sunday, eight Nordic and Baltic nations called on Georgia to consider holding new parliamentary elections.
"We are seriously concerned about the situation in Georgia," Lithuania, Latvia, Estonia, Finland, Sweden, Norway, Denmark and Iceland said in a joint statement.
"We have called for a thorough and impartial investigation into the irregularities reported ahead of and during the parliamentary elections on October 26. We have condemned violence and intimidation against peaceful protesters, politicians and media representatives; and we deplore the threats directed towards President Zourabichvili," reads the statement released by the Lithuanian Foreign Ministry.
The Nordic and Baltic nations expressed their "alarm" over Georgia's "path toward deeper polarisation and crisis".
"Georgia urgently needs a way out of the crisis, and to restore public trust in its democratic institutions," they said.
"We urge the Georgian authorities to take immediate steps in this direction, including by implementing OSCE electoral recommendations and by considering the possibility of new elections based on these recommendations," the joint statement reads.
Micheil Kavelashvili, a former footballer and far-right loyalist of the ruling Georgian Dream party, was sworn in as Georgia's new president during a parliamentary ceremony on Sunday.
Thousands of people protested outside the parliament against the inauguration amid concerns it would exacerbate the political crisis marked by massive pro-European demonstrations.
Outgoing President Salome Zourabichvili and the opposition have declared Kavelashvili's election "illegitimate".
On the eve of the inauguration, Lithuanian President Gitanas Nausėda warned that "Georgia risks repeating the Belarusian scenario" as the ruling party stalls the country's European integration process.
He added that Lithuania "strongly supports the European Parliament's call for new parliamentary elections in Georgia".
Western nations, as well as Lithuania, have imposed sanctions on Georgia's officials and members of the Georgian Dream party over human rights violations.
