On the basis of a fruitful cooperation for more than twenty years within the framework of a standing open call and to harmonise the working procedures the DFG and the Russian Foundation for Basic Research (RFBR) have opened the possibility for funding of joint German-Russian projects in all areas of basic research for the period of 2018–2020. Due to the reintegration of the Russian Foundation for Humanities (RFH) into RFBR the new call includes research fields in the humanities and social sciences.
