The Southwest Indian Ocean at the Crossroads of Global Strategic Rivalry
Long overlooked in the chessboard of global power, the southwest Indian Ocean — encompassing the Mozambique Channel and its African coastlines — has emerged as one of the world's most hotly contested zones. Energy security, maritime control, military projection, space diplomacy, and access to critical resources are all converging in this region. Global and regional powers are recalibrating their positions, while African states seek to convert their strategic exposure into a source of sovereign strength.
France returns to the region
France's return to the region, after a decade of relative disengagement, marks more than a tactical correction. It reflects a broader strategic reorientation, anchored in an essential partnership with India. Paris and New Delhi are building politico-military interoperability against a backdrop of energy diplomacy. Diego Suarez, Mayotte, and Tromelin are emerging as strategic nodes in a Franco-Indian axis, underpinned by shared stakes in Mozambique’s Rovuma Basin Area 1, where TotalEnergies, ONGC, and Bharat Petroleum together control nearly half the exploitation rights. This is hybrid diplomacy in action: a mix of joint military exercises, naval deployments, and coordinated investments in energy, logistics, and technology.
Through its SAGAR initiative ("Security and Growth for All in the Region"), India is evolving from a cautious regional player into a proactive stabilizing force. In 2025, it co-hosts the AIKEYME (Africa India Key Maritime Engagement ) exercises with eight African countries, reinforcing a sustained maritime presence from Zanzibar to Maputo via Port Louis. Yet India's ambitions face structural limits: it cannot match China’s economic clout or rival the U.S. in military projection. Instead, India opts for a pragmatic route — safeguarding energy corridors, cultivating flexible alliances, and branding itself as a "partner of first resort" against piracy, maritime terrorism, and environmental threats.
In Mayotte, France maintains a symbolically potent but increasingly fragile foothold. Challenged by Comorian claims, diplomatically cornered on migration, and facing criticism from emergent powers such as Russia, China, and Turkey, France is leaning on strategic partnerships: resource diplomacy with the UAE, diplomatic alignment with India, and multilateral engagement through the Indian Ocean Commission (IOC). But on the ground, its position is fraying. As other actors invest in the blue economy, satellite tech, fisheries, and dual-use infrastructure, Mayotte risks becoming a weak link in a rapidly shifting strategic architecture.
While France shores up its historical bastions, Russia is pursuing a quieter, targeted approach. In Mauritius, Russia’s cooperation with the Mauritius Research and Innovation Council (MRIC) in space technologies acts as a Trojan horse for a new wave of "orbit diplomacy." Using satellites, maritime surveillance, and remote sensing, Moscow is extending its reach through innovation and soft power. It avoids open confrontation, preferring to exploit the vacuums left by receding Western influence.
The Mozambique Channel is now a hotspot where global energy, mining, and logistical interests collide. Offshore deposits in Rovuma and Mnazi Bay are accelerating regional militarization: acoustic sensors, drones, radars, and patrols are increasingly deployed to safeguard infrastructure and monitor sea lanes. In Cabo Delgado, insurgent violence endures despite Rwandan military efforts. A fragmented security landscape has emerged — a patchwork of private contractors, national forces, NGOs, and militias. France, via TotalEnergies, is striving to secure its assets while retaining sovereignty over strategic resources.
The United States, meanwhile, maintains a more discreet yet methodical presence. An outpost in Voidju (Grande Comore) links it to key gas and mining zones. Madagascar, home to Africa’s largest, rare earth reserve at Ampasindava, has become a strategic linchpin under U.S. oversight, with Australia playing a key role through the QUAD framework. Washington favours a "shadow presence": surveillance, influence operations, logistical hubs — all designed to secure critical supply chains without overt military engagement. The goal is not territorial control, but strategic access in the context of the Sino-American rivalry.
Conclusion: One Sea, Many Stakes, Emerging Fault Lines
By 2025, the western Indian Ocean is no longer a geopolitical afterthought. It is a central arena in the reordering of global power — where established powers, emerging challengers, and aspiring African sovereignties all intersect. The race to control sea lanes, resource flows, and maritime influence is relentless, without fixed alliances or clear boundaries. In this context of fluid rivalries and overlapping ambitions, the Mozambique Channel reflects the broader tensions shaping the international order. No longer just a maritime corridor, it has become a theatre of global competition.

The Southwest Indian Ocean at the Crossroads of Global Strategic Rivalry

Uvira Buckles Under Pressure
Nestled along the shores of Lake Tanganyika, the strategic city of Uvira now finds itself on the edge. Since early 2025, M23 rebel forces, supported by the Congo River Alliance, have gradually tightened their grip on this once-thriving hub of 726,000 residents. Once a bustling commercial centre, Uvira has become a frontline battlefield where the Armed Forces of the Democratic Republic of the Congo (FARDC), backed by local Wazalendo militias and Burundian reinforcements, are fighting a desperate rear-guard action. Amidst this turmoil, the local civilian population, caught in the crossfire, endures the heaviest toll. A Blistering Offensive The situation took a dramatic turn on February 18 when M23 forces seized Kamanyola, a locality 75 kilometres north of Uvira, inflicting a severe blow on FARDC forces and forcing them to retreat. Within 24 hours, Uvira plunged into chaos—gunfire echoed through the streets, looting erupted, and over 500 prisoners staged a dramatic escape from Mulunge prison. Faced with mounting violence, thousands of residents fled toward neighbouring Burundi or sought refuge in relatively safer towns like Kalemie and Moba, leaving behind only about 20% of the population in a city that increasingly resembles a ghost town. Internal Fractures and Fratricidal Clashes By February 25, internal discord erupted as infighting broke out between FARDC and their Wazalendo allies, resulting in 20 deaths and 60 wounded. Although the Wazalendo managed to temporarily reclaim positions such as the Kaziba chiefdom, the relentless advance of M23 forces continued unabated. Village after village in the Uvira highlands fell under rebel control, and defections from local militias further undermined an already fragile defence. Burundi Steps In In a bid to stem the rebel tide, Burundi—an ally of Kinshasa—deployed troops across the Ruizi River into Luvungi. However, the intervention has only added to the uncertainty: questions remain about the ability of these reinforcements to halt the M23 advance amid persistent suspicions of covert support from Rwanda. The situation on the ground remains volatile, with the ultimate outcome still unknown. A Deepening Humanitarian Crisis As the fighting intensifies, the humanitarian situation worsens. Hospitals are overwhelmed by the influx of wounded, while markets, pharmacies, and banks remain shuttered. Civilians left in the lurch find themselves trapped in a desperate struggle between fleeing and merely trying to survive, with scant help or hope of escape. The Noose Tightens By April 2025, anxiety in the region had reached a fever pitch. In a massive redeployment along the Bukavu–Uvira axis observed between April 11 and 16, M23/AFC forces appear to be gearing up for the capture of Uvira, with a potential further push toward Kalemie on the horizon. This military buildup is fanning widespread fear among the population, especially in light of past abuses in rebel-controlled areas and comes despite diplomatic efforts aimed at averting an outright occupation of the city. A Fragile Glimmer of Diplomacy Amid the carnage, a slender thread of hope has emerged through diplomatic channels. Peace talks, brokered by Qatar, began early in April with an initial session on the 7th and a follow-up scheduled for the 9th. Yet on the ground, the disconnect remains palpable—as fighting persists unabated and ceasefire promises are repeatedly broken. Uvira: A Symbol of Endless Conflict Once a thriving urban centre, Uvira now stands on the brink. Besieged by relentless M23 attacks, fragmented FARDC counterattacks, internal divisions, and regional power plays, the city has become a stark symbol of eastern Congo’s enduring tragedy. Civilians bear the ultimate cost of this unyielding conflict. With only around 6,000 Wazalendo fighters still defending Uvira, a desperate appeal has been made to President Tshisekedi for additional ammunition and supplies. Recent clashes, which claimed at least 17 Burundian soldiers in Rugezi, underscore the grim reality: Uvira is now squarely in the rebels’ sights, its future uncertain, and its people paying the highest price for an endless war.
