Police in the former Soviet state of Georgia have used water cannon and teargas in an attempt to disperse thousands of people who rallied on Tuesday night after parliament gave its initial backing to a draft law on “foreign agents” which critics say represents an authoritarian shift. Some protesters threw petrol bombs and stones at police in the centre of the capital Tbilisi, as demonstrators warned that the draft law could hurt the south Caucasus country’s hopes of EU membership. The law, backed by the ruling Dream party, would require any organisations receiving more than 20% of their funding from overseas to register as “foreign agents”, or face substantial fines. Critics have said it is reminiscent of a 2012 law in Russia that has since been used to crack down on dissent. Georgia’s president, Salome Zourabichvili, has said she intends to veto the law if it crosses her desk but the parliament could override her veto. She expressed solidarity with the protesters on Tuesday. “You represent a free Georgia, a Georgia which sees its future in the west, and won’t let anyone to take this future away,” she said in an address recorded in the US, where she is on an official visit. “Nobody needs this law … everyone who has voted for this law has violated the constitution,” she said. Protesters angrily remonstrated with police armed with riot shields who then used teargas and water cannon. At least three petrol bombs, as well as stones, were thrown at police. People suffering from the effects of teargas were being treated on the steps outside the parliament building. “I came here because I know that my country belongs to Europe, but my government doesn’t understand it”, said 30-year-old protester Demetre Shanshiashvili. “We are here to protect our country because we don’t want to be part of Russia again,” he added, referring to the almost two centuries Georgia spent as part of the Russian Empire and Soviet Union. Earlier, the law had comfortably passed its first parliamentary reading, Georgian media outlets reported. Some of the protesters gathered outside the parliament building carried Georgian, EU and US flags, and shouted: “No to the Russian law,” and “You are Russian” at politicians inside the legislature. Russia is viewed as an enemy by many Georgians, after Moscow backed separatists in the breakaway Georgian regions of Abkhazia and South Ossetia in the 1990s. Hundreds of thousands of Georgians remain internally displaced within the country after several bouts of bloody ethnic conflict. Speaking in Berlin on Tuesday, the Georgian prime minister, Irakli Garibashvili reaffirmed his support for the law, saying the proposed provisions on foreign agents met “European and global standards”. The ruling party, which says it wants Georgia to join the EU, has accused critics of the bill of opposing the Georgian Orthodox Church, one of the country’s most respected and influential institutions. On Monday, a committee hearing on the law ended in a brawl in parliament. More than 60 civil society organisations and media outlets have said they will not comply with the bill if it is signed into law. Georgia’s government has in recent years faced criticism from observers, who say the country is drifting towards authoritarianism. In June, the EU declined to grant Georgia candidate status alongside Moldova and Ukraine, citing stalled political and judicial reforms.
