This chapter aims to explore some of the specificities of the urban planning knowledge transfer between Croatia, in the early period of the socialist Yugoslavia, and the newly independent Guinea, through a detailed examination of objectives, planning principles and solutions as well as the apparent (im)possibility of implementation of the Urban Development Plan of Conakry prepared by the Croatian Urban Planning Institute in 1961-1963. This engagement of the Croatian Urban Planning Institute was facilitated by the new position of Yugoslavia after the termination of the political relationship with the Soviet Union. The participation of Yugoslavia in the Non Aligned Movement led to the establishment and development of friendly relations with a large number of African and Asian countries. From the perspective of architecture and urban planning, this new political position was responsible for the rupture with the paradigms of the socialist realism and a more open attitude towards western tendencies. The comparison of Urban Development Plans of Zagreb and Conakry developed in the same period reveals clearly the existence of a common planning approach. This means that Croatian planners adopted similar designs, urban layouts and architectural solutions for historically, culturally and geographically distant countries.
