"All necessary steps are being taken against these unilateral acts of Greece and GCA [Greek Cypriot Administration] both on the ground and at the [negotiation] table," the ministry said in a statement.
The GCA has announced its plan to have an Italian-owned ship under the Maltese flag begin research on Sunday and its intention to start a new drilling operation in southern Cyprus in November.
"All these unilateral acts will increase tension in the East-Med [East Mediterranean] and threaten peace and stability," the Turkish ministry said.
Northern Cyprus is still awaiting a response from the Republic of Cyprus on a proposal to hold a conference on the Eastern Mediterranean, Turkish Cypriot President Ersin Tatar told Sputnik last month.
