The governments of both Greece and Turkey expressed their support for renewed peace talks. The declaration was also welcomed by the European Union. On 13 February 2014, Archbishop Chrysostomos lent Anastasiades his backing on the Joint Declaration. On 14 February 2014, the Greek Cypriot negotiator Andreas Mavroyiannis and Turkish Cypriot negotiator Kudret Özersay held their first meeting and agreed to visit Greece and Turkey respectively. Reactions among the Greek Cypriot political parties were mixed. The opposition AKEL party declared its support for the declaration. However, Nicolas Papadopoulos, the leader of DIKO, the main partner to Anastasiades' party DISY in the governing coalition, opposed the declaration, and DIKO's executive committee voted on 21 February to recommend to the party's central committee that the party withdraw from the coalition from 4 March. On 27 February, DIKO decided to leave the coalition government, with the explanation that the Joint Declaration had conceded separate sovereignty to Turkish Cypriots. On 15 May 2015, in the first Akıncı-Anastasiades negotiation meeting, Northern Cyprus lifted visa requirement for Greek Cypriots, and Anastasiades presented maps of 28 minefields in the north, near the mountainous region of Pentadaktilos.
