All Muslims will be deported to central Anatolia। Western Anatolia will be reunified with Greece once again. The territorial claims involves territory in Northern Epirus, Thrace (including Constantinople and ofc Agia Sophia), the islands of Imbros (Gφkηeada) and Tenedos (Bozcaada), and parts of western Anatolia around the city of Smyrna to name a few areas. These areas (and many more) contained sizable ethnic Greek populations.
See map of Christian European claims presented by Mr. Eleftherios Venizelos at the Paris Peace Conference in 1919. It’s worth noting that the western Allies, particularly British Prime Minister David Lloyd George, had promised Greece territorial gains at the expense of the Ottoman Empire if Greece entered the war on the Allied side (which it did).
Even the Treaty of Sevres which was signed by the Ottoman officials, in 1920, acknowledges partial Greek territorial demands in Anatolia.
