Corporate Diplomacy and Multinational Oil Companies in Nigeria’s Foreign Relations

This study examines the role of multinational oil companies (MNOCs), particularly Shell, Chevron, TotalEnergies, and ExxonMobil, as informal diplomatic actors in Nigeria's foreign relations, assessing the mechanisms through which their lobbying, corporate communications, and bilateral engagements with home-country governments shape Nigeria's external environment. MNOCs in Nigeria are not merely commercial actors but politically significant entities that engage host and home governments simultaneously, creating complex webs of influence that affect Nigeria's foreign policy space. Drawing on corporate diplomacy theory and international political economy, this research analyses three cases of MNOC diplomatic influence on Nigeria's foreign relations between 2019 and 2024, including divestment negotiations, environmental litigation involving Dutch courts, and home-government pressure on Nigerian regulatory policy. The study employs a qualitative methodology, drawing on company annual reports, investor relations documents, academic investigative research, and expert interviews with oil sector lawyers and policy scholars. Particular attention is paid to the South South zone, where oil operations are concentrated and where the interactions between corporate diplomacy, local grievances, and state authority are most visible. Findings are expected to demonstrate that MNOCs exercise significant informal diplomatic influence but in directions that often diverge from Nigeria's stated foreign policy interests.
