Unilateral concessions in the Karabakh settlement will only deepen the existing dangers and threats, Armenian President Serzh Sargsyan said in an interview to the Syrian Al-Watan newspaper. 

"Contrary to the claims of Azerbaijan, we do not populate and use the territories, which are the security zone of Nagorno-Karabakh. 

"When the people of Nagorno Karabakh get a real opportunity to exercise their right to self-determination and when working instruments of security and development are created, then Armenia may consider the return of security zone regions around NKR as a mutual concession, preserving the corridor linking Armenia to Karabakh," Serge Sargsyan said, adding that he has repeatedly stated this. 

According to the President of Armenia, the key idea of "mutual concessions" is reciprocity.
