The Greek prime minister has intervened on presidential decrees to extend territorial waters of the country, a Greek news agency reported on Wednesday.

Quoting diplomatic sources, ANA-MPA said Alexis Tsipras, who has recently been sworn in also as foreign minister, attended a meeting on issues related to territorial waters and relations with Turkey at the Foreign Ministry.

Tsipras reportedly decided to stop the presidential decrees to extend territorial waters of Greece to 12 miles in some areas and decided to bring them to the parliament as draft laws to be discussed with other parties.

He also directed for preparations for his visit to Istanbul on Turkish President Recep Tayyip Erdogan's invitation.

Also on Wednesday, Turkish Defense Minister Hulusi Akar said he expects neighboring Greece to act in "good sense" on the issue.

Turkey's Foreign Ministry summoned the Greek ambassador in Ankara on Tuesday.

The move came after remarks by Nikos Kotzias, who recently resigned as Greek foreign minister.

Kotzias said that Greece was ready to extend its territorial waters from six miles to 12 miles in the Ionian Sea and two other areas.

A declaration of Turkish parliament in 1995 warns that if Greece increases its territorial waters in the Aegean Sea beyond six miles, the Turkish parliament will give "all powers", including military powers, to the government to defend Turkey's interests.

Turkey's Foreign Ministry said on Tuesday that the declaration "is still in force today".
