MOSCOW, May 15. /TASS/. Foreign Ministers of Sweden, Finland and Turkey Ann Linde, Pekka Haavisto and Mevlut Cavusoglu discussed NATO’s open door policy on the sidelines of an informal meeting of the alliance’s top diplomats in Berlin on Saturday.

"Important meeting with my [Finnish colleague] @Haavisto and my [Turkish colleague] @MevlutCavusoglu. We discussed the deteriorated security situation and [NATO’s] open door policy," Linde wrote on her Twitter page. Earlier, the Swedish top diplomat reported that she hoped to convince her Turkish counterpart with regards to the issue of Sweden joining the alliance.

In early April, the discussion of Finland’s possible NATO membership intensified. The main members of the alliance supported this initiative. In Finland, the majority of the members of the parliament upheld the idea of joining the bloc. Sweden is also considering joining NATO and the ruling Swedish Social Democratic Workers’ Party (SAP) will make a corresponding decision on May 15.

Earlier, Turkish President Recep Tayyip Erdogan said that Ankara did not consider the probability of these two countries’ accession to NATO positive, because "Scandinavian states are a guest house for terrorist organizations," referring to the PKK, outlawed in Turkey. On Saturday, Cavusoglu reiterated this stance. He noted that the majority of Turkish residents are against Finland’s and Sweden’s accession to NATO and ask Ankara to block this process, however it intended to discuss this with its NATO allies as well as with Helsinki and Stockholm.
