Greek Prime Minister Alexis Tsipras visits Turkey on Tuesday to hold talks with Turkish President Recep Tayyip Erdogan, aimed at easing tensions over bilateral disputes and the long-running Cyprus problem. The two leaders are expected to discuss disputed Cyprus energy exploration, Aegean sea issues, a migrant deal and economic cooperation though analysts see little concrete progress. “We are going through a difficult period in our relations with Turkey, which is why we have to continue to discuss,” Greek government spokesman Dimitris Tzanakopoulos said. “This visit can contribute to de-escalation of tensions.” In December 2017, Erdogan became the first Turkish president to visit Greece in 65 years. He stunned his hosts when he asked for a revision of the 1923 Lausanne Treaty that defines the borders of modern Turkey after the collapse of Ottoman Empire, AFP said.
