The document discusses international collaboration between INRIA and FAPs research funding agencies in Brazil. It provides an overview of INRIA's strategy shift in 2010 to sign agreements with multiple FAPs to launch joint funding calls. The first two joint calls selected 11 projects out of 17 submissions and 3 projects out of 6 submissions, respectively. Main challenges discussed include refining the project calendar, differences between INRIA and CNRS models for project selection, syncing call timelines between FAPs, cases where FAPs agreed but did not participate, and needing evolution and evaluation of future collaboration.
