The text of the memorandum signed by all three leaders says that Finland and Sweden will “extend their full support” to Turkey in matters of national security.
The Nordic countries said they confirmed that the PKK was a proscribed organisation and, in a key concession, would “not provide support” to the Syrian Kurdish Democratic Union party (PYD) and People’s Protection Units (YPG) groups that have been active in the fight against Islamic State in Syria.
Finland and Sweden affirmed in the deal there were no national arms embargoes relating to sales to Turkey and all three countries said they would work together on extradition requests.
Sweden is home to 100,000 Kurdish refugees and Turkey has called for the extradition of individuals it says are linked to the PKK or the Syrian YPG.
Stoltenberg said Finland and Sweden had agreed to a “further amending their domestic legislation” to give Turkey the anti-terror reassurances it had sought, and would be “cracking down on PKK activities” and “entering into an agreement with Turkey on extradition”.
