The Republic of Equatorial Guinea (EG) joined the Forum for Economic and Trade Cooperation between China and Portuguese-speaking Countries (Forum Macao) in 2022, becoming the tenth member-state. This occurred during the 2022 Extraordinary Ministerial Conference, after it acceded to the Community of Portuguese-Speaking Countries (CPLP) in 2014. Since 2015, China and EG have been intensifying their bilateral cooperation after establishing a comprehensive cooperative partnership (Ministry of Foreign Affairs of the People’s Republic of China, 2015). In 2019, the two countries signed a Belt and Road Initiative (B&RI) MoU during the second Belt and Road Forum in Beijing, and initiated a strategic approach for bilateral cooperation. Consequently, considering the uniqueness of EG as a Portuguese-speaking Country (PSC) and as the newest member of Forum Macao, this paper poses and answers the following research question: What will be the impact of Sino-Equatoguinean cooperation in light of EG’s recent accession to FM? Methodologically, the research uses qualitative data supported by triangular referencing, including official and non-official sources, namely official statistics, academic papers, and media reports, to look into the bilateral Sino-Equatoguinean relations under the B&RI Lusophone framework, as well as the fact that EG is a CPLP memberstate. Accordingly, the methodologic rationale focuses on the uniqueness of EG as one of the Lusophone countries and relates it to the Chinese B&RI at three levels: domestic, regional and global. This paper is organized as follows: (1) Introduction; (2) The uniqueness of EG as a PSC; (3) The B&RI and the Lusophone Countries; (4) Cooperation between Equatorial Guinea and China; (5) Conclusion – The Future of Sino-Equatoguinean Cooperation
