Deputy Prime Minister Hakan Cavusoglu spoke at a dinner given in honor of the Western Thrace Turkish Minority Advisory Board in Komotini, also known as Gumulcine in Turkish.
Turkey's Greece-born deputy prime minister met representatives of a Turkish minority group in his hometown, Western Thrace's Komotini city.
Hakan Cavusoglu has been in Athens since Thursday ahead of a historic trip by President Recep Tayyip Erdogan, saying good neighborly relations would benefit both countries.
Cavusoglu said that Turkey is aware of the challenge the Turkish minority is facing in the region, which is home to around 145,000 Muslim Turks.
"Turkey is always on the side of minority societies, and will continue to do so,” Cavusoglu said.
In his remarks, Cavusoglu also cited the Turkish minorities in Bulgaria, Kosovo, Macedonia as well as Turkic republics, who he said shared the same fate with those in Western Thrace.
On his talks during his visit to Athens, Cavusoglu said Turkish-Greek relations were addressed, adding that it is important to have "open communication networks" between the two countries.
Cavusoglu was born in 1972 in Deilina, a village near the city of Komotini (Gumulcine in Turkish), where many of his relatives remain.
