The Personal Representative of the OSCE Chairperson-in-Office believes there are grounds for optimism in the Nagorno Karabakh conflict settlement, Trend News reported.

“Azerbaijani and Armenian Presidents Ilham Aliyev and Serzh Sargsyan have made it clear that they intend to build on the momentum of their meetings and intensify the peace process,” Andrzej Kasprzyk said, adding, "In the last few weeks I have heard cautiously optimistic assessments from Armenian and Azerbaijani officials."

"Presidents Aliyev and Sargsyan have called for additional steps to strengthen the ceasefire and carry out confidence-building measures in all fields in order to create a better atmosphere for the negotiations," he said.

"One of the confidence-building measures would be to develop humanitarian contacts among the two sides’ intelligentsia, academic and public circles," Kasprzyk said.

Moreover, Kasprzyk's team has been helping to elaborate a mechanism for investigating potential incidents.
