Tense start to Turkish president's Greece visit
The leaders of Greece and Turkey have publicly aired their grievances in a tense news conference as a two-day visit to Athens by Turkish President Recep Tayyip Erdogan got off to a rocky start.
The Greek government had expressed hopes the visit, the first to Greece by a Turkish president in 65 years, would help improve often frosty relations between the two neighbours.
The Nato allies are divided by a series of decades-old issues, including territorial disputes in the Aegean Sea, and have come to the brink of war three times since the early 1970s.
But from the outset, discussions focused on disagreements.
On the eve of his visit, Mr Erdogan rattled his Greek hosts by saying in an interview with Greece's Skai television that the 1923 Treaty of Lausanne should be "updated".
The treaty delineated modern Turkey's borders and set provisions for the status of the Muslim minority in Greece and the Greek minority in Turkey, among other issues.
In a visibly testy first meeting with Greek President Prokopis Pavlopoulos, the two engaged in a thinly veiled verbal spat over the treaty and the Muslim minority, which Mr Erdogan is to visit on Friday.
"This happened in Lausanne, that happened in Lausanne. I get that, but let's now quickly do what is necessary," Mr Erdogan told Mr Pavlopoulos.
"Many things have changed in 94 years. If we review these, I believe that all the sides will agree that so many things have to (change)."
The spat continued during Mr Erdogan's appearance at an unusually candid joint news conference with Prime Minister Alexis Tsipras.
The two listed a series of grievances their countries have with each other, including religious and minority rights, the divided island of Cyprus and the case of 10 Turkish servicemen who have applied for asylum in Greece following a Turkish government crackdown after a failed coup last year.
"It is very important to strengthen our channels of communication, and this can only happen on the basis of mutual respect," Mr Tsipras said.
The prime minister said the two also discussed tension in the Aegean, where Greece complains Turkish fighter jets frequently violate its airspace.
"The increasing violations of Greek airspace in the Aegean and particularly the simulated dogfights in the Aegean pose a threat to our relations, and particularly a threat to our pilots," Mr Tsipras said.
For his part, Mr Erdogan insisted once more that the Lausanne treaty needed to be reviewed, but stressed his country had no territorial claims on its smaller neighbour.
On the topic of the Muslim minority in Greece - which the country recognises only as a religious minority, while Turkey has long pressed for better rights - Mr Tsipras said his government agreed that improvements must be made in their quality of life.
"But issues that concern reforms involving Greek citizens are not an issue of negotiation between countries," he said.
Mr Tsipras noted it was unclear exactly what Mr Erdogan was seeking with his call for an update to the 1923 treaty.
"The truth is I am a little confused about what he is putting on the table," he said.
Greeks have been aghast at Mr Erdogan's comments in the past over possibly revising the Lausanne treaty, considering the move could harbour territorial claims.
His bringing up the issue on the eve of and during his visit to Athens was not a move welcomed by his hosts.
Mr Erdogan and Mr Tsipras also sparred over the issue of Cyprus, divided since a 1974 Turkish invasion into a Turkish-occupied north and an internationally recognised Greek Cypriot south.
Another round of internationally brokered peace talks to reunify the island failed earlier this year.
"Who left the table? Southern Cyprus did ... We want the issue to reach a fair and lasting solution but that is not southern Cyprus's concern," Mr Erdogan said.
Mr Tsipras retorted: "My dear friend, Mr President, we must not forget that this issue remains unresolved because 43 years ago there was an illegal invasion and occupation of the northern part of Cyprus."
Mr Erdogan also raised the issue of Athens having no official mosque, to which Mr Tsipras responded by saying Greece had restored several mosques around Greece, including a centuries-old mosque in central Athens.
The refugee crisis appeared to be the only issue the two sides did not disagree on, with both noting they had shared a significant burden of the migration flows into the European Union.
More than a million people crossed from Turkey through Greece at the height of the crisis.
