Since 1960s when the Cold war situation changed and the Aegean dispute, Cyprus conflict and other conflicts emerged Turkish-Greek cooperation ended. Since 1960s both countries’ bilateral relations deteriorated due to emergence of wide range of confrontational issues like escalation of Cyprus conflict in mid 1960s and disagreement on the Aegean Sea issue, especially on the issue of exploration and exploitation of mineral resources from Aegean Sea and Turkish military invasion in 1974 in Cyprus. For the first time, conflict on Aegean Sea had emerged due to disagreement over continental shelf in mid 1960s. Due to exploration activity both countries came on the brink of war in 1976 and 1987 during cold war period. A series of confrontations on Aegean Sea issue emerged during cold war period. This study will discuss major causes of confrontation between Turkey and Greece. Again in 1982 conflict emerged between two countries due to Greece’s sovereignty claim over territorial waters up to 12-nautical miles in the Aegean Sea. Apart from Aegean Sea dispute, Cyprus problem was another issue which led to deterioration of bilateral relations during cold war period. Turkey’s invasion of Cyprus in 1974 was a turning point for Turkey-Greece relations. Turkey’s Cyprus invasion was perceived by Greece as a major threat to its national security which was more than the threat of Warsaw pact during Cold war. This threat perception continued during the 1990s. On the other hand, during Cold war period Turkey believed that Greece’s policy towards Aegean and Cyprus was concerned with Greece’s megali ideas. This study aims to analyse and examine rapprochement approach between Turkey and Greece.
