On 8 and 9 November 2017, all awarded Horizon 2020 Widening projects (i.e. teaming, twinning and era chairs) gathered in Brussels to exchange experiences and best practices. Participants provided policy feedback to the European Commission on best ways to implement projects. They also explored cross-overs between the 3 Widening instruments in order to create an on- & offline Widening community in which these prestigious projects will participate. The next edition will take place in autumn 2018.
