Zagreb has responded to the note in which Slovenia accuses Croatia of prejudging the demarcation of the sea border, Croatia oaccusing Ljubljana of aspiring to Croatian territory and announcing that Croatia will report Slovenia to the European Union and the United Nations.

Slovenia sent a protest note to Croatia last Friday accusing it of claiming the part of the Adriatic Sea, which the successors to the former Yugoslavia have still not divided, by extending oil company INA's concession to drill for oil and gas in the Adriatic. In a press release on Monday, Croatia's Ministry of Foreign Affairs and European Integration said it had sent Ljubljana a note vehemently protesting against Slovenia's attempt "to state, more directly than before, an open and clear intention to claim Croatian state territory, namely territory over which the Republic of Croatia has sovereign rights and jurisdiction".

The ministry said it would notify relevant EU and UN bodies as well as other international factors of Slovenia's attempt to claim foreign territory. The ministry said it "rejects the interpretation that there is a so-called undivided Adriatic Sea, which is unacceptable under international law". The sea is not and cannot be the subject of succession because it belongs to the land and depends on the land which Croatia succeeded as one of the successors to the ex-Yugoslavia, the ministry said.
