The People’s Democratic Republic of Yemen, the only explicitly Marxist state in the Arab world, built dynamic collaborations with Eastern Bloc countries starting in the 1970s. This partnership involved substantial support from socialist nations, including Hungary, which sent experts to South Yemen to work on improving the state’s infrastructure and underdeveloped economic sectors. One of these individuals reported to the III/I Directorate of the Ministry of the Interior under the code name “Dunhill”. The present study focuses on the portrait of the era discernible in the reports by “Dunhill” and contextualize the information recorded therein. The analysis addresses key themes such as the unique characteristics of South Yemeni society, the economic and social conditions of the Arab state, and the status and varying perceptions of foreign workers in the host country, with a particular emphasis on Hungarian representatives. Additionally, the authors offer an introductory overview that characterize the areas, intensity, and significance of South Yemeni-Hungarian cooperation in the early 1980s. Their findings aim to contribute to the international discourse on the goals, nature, content, and significance of the relations between Eastern European states and the “Third World.”
