The aim of this meeting was on the one hand to identify the issues related to international mobility among young people, and on the other hand to discover and share innovative practices related to social issues (digital technology, the fight against discrimination, sustainable development, the intercultural approach) for young people 12-25 years old. This mobility was therefore part of a second stage of a larger international exchange project. Based on a first meeting in March 2020, the ICJ and the FRMJC wanted to work together again in order to explore, question and develop the capacity of youth organizations to design a project in line with their audience and the challenges of society. that cross them. It is with this in mind that this second study visit took place in September 2021, which aimed to: - Bring (re) meeting professionals and volunteers working in similar contexts in "the other country" - Allow them to report on the evolution of the reflection carried out 6 months previously. - Discover innovative actions implemented by other operators, and thus enrich practices (actions implemented thanks to the first mobility or pre-existing to it) - Cross-analyze practices in order to refine the understanding of the issues involved and the processes that support them. Thus, the FRMJC and the ICJ, in consultation with the actors of their networks, extended the experience of international exchange in order to further enrich the development of actions towards the 12/25 age group
