The Turkish-flagged drillship Fatih launched offshore drilling operations this May in an area 75 kilometers (42 nautical miles) off the western coast of the island of Cyprus.
The Armenian Foreign Ministry has issued a statement on Turkey's attempt to conduct a new drilling operation in Cyprus's Exclusive Economic Zone (EEZ), calling on Turkey to abandon its plans.
In June, EU leaders warned Turkey to end drilling in waters around the island or face action from the bloc.
The ministry said on Wednesday the European Union could not be an impartial mediator on the Cyprus dispute, and that Turkey's Fatih ship had started drilling activities off the Mediterranean island at the start of May.More news: France says Javelin missiles found in Libya were 'unusable' - army ministry
"This provocative step raises tensions in the region", it added.
Turkey and the internationally-recognised government of the divided island have overlapping claims in that part of the Mediterranean, an area thought to be rich in natural gas.
Its Yavuz ship had recently arrived to the east of Cyprus and would conduct drilling activities.
The ministry said being a member of the European Union and "allegedly representing the entire Island" does not give the Greek Cypriot Administration the right to usurp the legitimate rights and interests of the Turkish Cypriots.More news: Gatwick Airport suffers complete failure of air traffic control
The discovery of huge gas reserves in the eastern Mediterranean has set off a race to tap underwater resources, sparking a dispute between Turkey and European Union member Cyprus.
The United States and Egypt also joined a chorus of criticism this week, with Washington urging Turkish authorities "to halt these operations".
Cyprus has been split between a Turkish Cypriot north and Greek Cypriot south since 1974 when Turkey sent troops to the island in response to a Greek military coup.
Brussels called on Monday Turkey's "unnecessary escalation" and urged Ankara to stop drilling because it is illegal and can bring economic sanctions to them.More news: Piers Morgan to The Duchess of Sussex: 'Go back to America'
