The Indian Ocean plays a crucial role in global geopolitics, trade, and security. Serving as a vital link between Europe, Asia and Africa, it facilitates the flow of commerce and energy supplies, making a key strategic corridor. The region’s importance is underscored by critical chokepoints that are both essential for global trade and vulnerable to disruption. For European nations, ensuring the stability of these maritime routes is vital for economic and energy security. The strategic landscape of the Indian Ocean is increasingly shaped by geopolitical competition, particularly with the growing influence of China through infrastructure investments and military expansion. In response, European countries have sought closer security and economic ties with India, a dominant regional player, through military cooperation and strategic engagement. However, the challenge remains in balancing partnerships while addressing the broader implications of China’s presence. This paper explores the Indian Ocean’s strategic significance to Europe, analysing the key drivers of collaboration, competition, and security challenges. As geopolitical rivalries intensify, European nations must adopt a proactive approach to safeguard their interests and maintain influence in this critical maritime domain.
