Different Forms of Summit Diplomacy. Case Study Analysis of the Visegrád Group, the Bucharest Nine, and the Three Seas Initiative.

This article delves into the nuances of summit diplomacy in regional formats within Central Europe, with a particular emphasis on the Visegrád Group (V4), the Bucharest Nine (B9), and the Three Seas Initiative (3SI) from 2015 to 2023. Though each format functions differently, all rely on summit diplomacy to achieve their objectives. The article aims to explore the reasons why informal regional formats are frequently implemented in this region. The study conducts a thorough review of existing literature. It systematically analyses past instances of the selected formats, considering variables such as meeting frequency, location, and the level of representation. Based on the adopted definition of summit diplomacy, this article classifies the meetings of the highest level during the specified period as personal meetings between political leaders from at least two countries with official, state roles, such as presidents, prime ministers, or ministers. These leaders hold significant power to shape their country’s foreign policy and influence the legal and political order through summit decisions, while engaging with counterparts from other nations. The paper also highlights the variations between the above-mentioned formats in Central Europe, including the differences in meeting frequency, level of representation, and the number of participating states.
