Sweden and Finland look poised to join NATO after Turkey agreed to drop a block on the Nordic countries' application.
"I am pleased to announce that we now have an agreement that paves the way for Finland and Sweden to join NATO," he said.
"Turkey, Finland and Sweden have signed a memorandum that addresses Turkey's concerns, including around arms exports and the fight against terrorism.".
Finland and Sweden will receive a formal invitation to join the organisation on Wednesday, which will then require further steps like domestic ratification.
The Nordic states' attempt to join the alliance hit a stumbling block when President Erdogan said they supported Kurdish militants.
In the memorandum, Finland and Sweden stated they would not support the YPG/PYD, and the group known in Turkey as FETO.
Turkey suddenly agreed to support a bid by Sweden and Finland to join the transatlantic alliance in a dramatic U-turn after days of last-ditch diplomacy. »
