"We will not adhere to any decisions that will be the result of a conference in Astana ... We believe that the negotiating parties and country guarantors are parts of a serious Syrian crisis, and they do not have solutions relevant to the people of Syria", the statement reads, Kazinform reported.
According to the Kurdish National Council, in order to solve the crisis it is necessary to hold consultations with representatives of all nationalities and religions of Syria.
This is the first time Damascus and the armed opposition sit together at the negotiating table since the start of the conflict in the Arab country.
The Astana talks have begun earlier in the day and Kazakh side expects the meeting to last through Tuesday.
