Recep Tayyip Erdogan's talks will come after clashes between police and protesters at Istanbul's Taksim Square lasted into the early hours of Wednesday. Police also used tear gas to disperse protests in the capital, Ankara.
Erdogan has warned that he will put an end to the gatherings, which he says are hurting Turkey's image and economy.
The protests erupted on May 31 after a violent police crackdown on a peaceful sit-in by activists objecting to a project replacing the park with a replica Ottoman-era barracks. They have become Erdogan's biggest challenge since he came to power a decade ago.
