Welcome everyone. Saqartvelo (საქართველო) is called Georgia in English, Gruzia in Russian, Gurjistan in Turkish and so on. In fact, the name of the country is the name that is read in the national alphabet. In your case, Lithuania is the country that called Georgia as Sakartvelo, for our part we also called Lietuva instead of Lithuania. It would be good if other countries would share this action and call the name, which is written in the national , a sign of respect.
Ps. For Georgian Russia is Ruseti,Turkey is Turketi, Albania is Albaneti, Serbia is Serbeti, Colombia is Qolumbia, Argentina is Argentina and e.t.c.
