"I am pleased to announce that we now have an agreement that paves the way for Finland and Sweden to join NATO," Stoltenberg told the media on the sidelines of a key NATO summit in Madrid, Spain.
"Turkey, Finland and Sweden have signed a memorandum that addresses Turkey's concerns, including around arms exports and the fight against terrorism," he added.
Stoltenberg went on to say: “No ally has suffered more brutal terrorist attacks than Turkey, including from the terrorist group PKK. The governments of Turkey, Finland and Sweden have agreed to enhance their cooperation on counter-terrorism.”
He added: “As NATO allies, Finland and Sweden commit to fully support Turkey against threats to its national security. This includes further amending their domestic legislation, cracking down on PKK activities, and entering into an agreement with Turkey on extradition.”
“In light of the progress we have made together, Turkey has agreed to support Finland and Sweden joining NATO,” Stoltenberg stated.
Stoltenberg said that on Wednesday NATO leaders would formally invite Finland and Sweden to join NATO.
