European and Southeast Asian ICT R&D collaboration has a successful and long history, but opportunities exist to create more synergies, leverage and value added. In order to secure higher and sustainable impacts, we propose to implement an intensified targeted support at the appropriate scale, involving EU and SEA Research, Development and Innovation knowledge networks, clusters and their organisations: a structured bottom up - top down approach helping to create synergies between research and innovation programmes in the EU and the SEA region and create sustainable strategic partnerships. The action will pave the way for jointly addressing important societal challenges and core technologies, at the research, innovation and policy levels under HORIZON2020 and relevant SEA regional and national programmes.Within this context, and building on the results and lessons learnt from the previous collaborative actions, the project has a three-fold objective: (1) To support internationalisation of European and SEA ICT-related research, development and innovation knowledge networks, technology platforms, clusters, organisations in the topics of common interest, in order to foster ICT RDI collaboration; (2) To promote Horizon 2020 and to reinforce synergies between the EU and ASEAN research development and innovation programmes; (3) To enrich and support EU-SEA ICT R&D policy dialogue, by supporting policy initiatives, summarising feedback from collaborative experience and proposing recommendations to reinforce EU-SEA ICT RDI collaboration.Specialists from EU and SEA knowledge networks - ETPs, Networks of Excellence, clusters, projects, organisations - will be invited to participate in the internationalisation process with their counterparts working on similar strategic topics and societal challenges. The CONNECT2SEA fund distributed via a call for participants will support the establishment of new collaborations. The project will contribute to promotion of Horizon2020 and collaboration opportunities. Pilot actions will be implemented, to support policy initatives. The feedback will contribute to policy recommendations.
