Both Sweden and Finland still need to take a series of measures to implement the memorandum signed with Ankara on combating terrorism, which is a condition for Turkey's approval of their membership in NATO, said Turkish Foreign Minister Mevlut Cavusoglu, reports NTV.

"They haven't taken any concrete steps yet. They have not met specific expectations on issues of extraditions and legal norms. Our president has also referred these issues to the Swedish prime minister. In general, the process is going positively, but there are still actions that need to be taken," the minister said, according to RBC.

 Most of the complaints are related to Sweden.

Cavusoglu said that Turkey would hold trilateral talks with representatives of Sweden and Finland at the summit of NATO foreign ministers in Bucharest tomorrow.
