Erdogan spoke as officials from Turkey, Sweden, Finland and NATO met on Wednesday in Ankara for talks to try to overcome Turkish objections holding up Sweden's NATO membership bid.
The parties agreed to continue working on the "prospective concrete steps" for Sweden's NATO membership, the statement said.
In justifying its objections to Swedish membership, Turkey has accused Stockholm of harbouring members of Kurdish militant groups it considers to be terrorists.
While he was having talks with NATO Secretary-General Jens Stoltenberg earlier this month, a similar protest was held in Stockholm, Erdogan said.
He added that he also told Stoltenberg Sweden should prevent such actions to secure Turkey's approval for its NATO membership.
