The International Research Infrastructure (IRI) programme governing the participation in and/or funding of international research infrastructure aims to support the Flemish participation in and/or funding of international investment initiatives that are carried out at large-scale international or supranational facilities to which the Flemish Government contributes and/or whose strategic importance for Flanders can be demonstrated.

The objective of the FWO's research projects is to advance fundamental scientific research. Researchers in all scientific disciplines may take the initiative to submit a proposal in this program.

In the context of the ‘Kom op tegen Kanker’ campaign, the FWO has a yearly budget available, to support patient-oriented research projects with a specific scope.

In collaboration with several European funders Weave supports researchers in Flanders to set up complete bi- or trilateral research projects with their European counterparts.
