Diverging perceptions of the "Visegrad Four + " format and the limits of the V4 + Japan cooperation.

The Visegrad Group format - coordinated policy forum for Czechia, Slovakia, Poland and Hungary - has been dubbed as a significant policy tool that advocates the interests and builds synergies among the four partners. The "Visegrad Four + " format, which coordinates foreign relations of these four countries, has been narrated as the key foreign policy venue of the V4, and the V4 + Japan is often understood as the key partnership within this format. Due to the recently growing Chinese influence in Central and Eastern Europe, and the impacts of the war in Ukraine in 2022, many have come to expect the coordination to strengthen and ramify. This article argues, however, that the V4 + Japan platform represents only a marginal policy forum and is unlikely to gain any significant political momentum in the foreseeable future. Basing the analysis on a set of interviews with the V4 and Japanese policymakers, the paper posits three reasons that have prevented the deepening of the V4 + Japan coordination: (i) there are significant limits to socialization in the group, (ii) there are diverse threat perceptions among V4 members, and (iii) there is little interest in deepening economic coordination vis-a-vis third parties. These findings question the viability of foreign policy coordination among the Visegrad Group members, and highlight the impediments for the expansion of V4 + Japan cooperation.
