Noting the necessity of establishing a dialogue between the divided opposition forces in Syria, CPFA along with Randa Kassis appealed to the President of Kazakhstan Nursultan Nazarabyev in order to reach a peaceful resolution to the crisis.

Two meetings were subsequently held in Astana in May and October 2015 under the aegis of the Minister of Foreign Affairs.
At the end of these meetings, two resolutions were signed by the participants, which led to the creation of the Astana Political Platform and helped pave the road for the Astana peace process.

CPFA and the Astana Political Platform continued their collaboration by initiating discussions between Syrian opponents in Geneva in February and July 2017 in order to develop a preparatory document for a reform of the Syrian constitution as part of a comprehensive political process.
This initiative was launched during the meetings regarding the formation of a constitutional committee and was later promoted during the National Congress of Sochi in January 2018 by Randa Kassis, despite the objections of the Syrian government and part of the opposition.

In 2018 CPFA launched an appeal to the Community of Sant’Egidio, whose contribution to peace over the past 50 years is indisputable, in order to achieve a balanced political settlement.
