The EU and Latin America and the Caribbean enjoy privileged relations and a strategic bi-regional partnership, which was launched in 1999. The Community of Latin American and Caribbean States (CELAC) is part of a flexible approach to its relations with Latin America and the Caribbean. The EU-funded EU-CELAC ResInfra project will identify CELAC research infrastructures eligible for the construction of bi-regional collaboration. It will build on the prioritisation results of the EU-CELAC Senior Official Meeting on Science and Technology (SOM) Research Infrastructure Working Group and, more specifically, will take as a reference the mapping exercises developed in previous EU-funded projects. The project will use the results and information obtained to draft a Sustainability Plan, which will include specific actions to support bi-regional collaboration.
