Congo-Brazzaville’s Quiet Maritime Diplomacy: Lessons from BRICS

Ce qu’il faut retenir

South Africa’s decision to host a week-long naval exercise involving China, Iran and Russia has revived a familiar dilemma for middle powers: how to pursue diversified partnerships without triggering punitive interpretations from a major trading partner. The episode offers a useful mirror for Congo-Brazzaville’s own maritime and economic diplomacy, where optics can weigh as heavily as capability.

The drill, launched on a Friday and led by China, was presented by South Africa’s defence department as an “intensive programme” focused on maritime safety operations, interoperability and protection of economic activity. Yet analysts quoted by the BBC stress that, in the current geopolitical climate, symbolism can complicate trade talks even when the stated objective is sea-lane security.

BRICS+ naval exercise: what happened and why it matters

Warships flying Chinese, Iranian and Russian flags were seen entering Simon’s Town, South Africa’s main naval base on the Cape Peninsula, shortly before the exercise began. A News24 report indicated that Pretoria hoped to persuade Iran to participate as an observer rather than as an active participant, a detail that underlines how carefully the host weighed perceptions.

The exercise is connected to the broader BRICS story. Launched in 2006 as Bric—Brazil, Russia, India and China—it became Brics after South Africa joined. With Egypt, Ethiopia, Indonesia, Iran and the United Arab Emirates added, the grouping is now referred to as Brics+ and is widely described as seeking to challenge the political and economic weight of wealthier Western nations.

US–South Africa tensions: trade, tariffs and political optics

The BBC report situates the drill against an already strained US–South Africa relationship. Commentator William Gumede, a professor at the University of the Witwatersrand, argued that Washington has perceived Pretoria as “anti-American” across administrations, and that renewed pressure under President Donald Trump has sharpened the stakes for a struggling economy.

In the same account, Trump accused South African authorities of failing to protect the white minority and offered Afrikaners refugee status. He also imposed higher tariffs and removed aid, moves that intensified scrutiny of South Africa’s foreign-policy choices. Pretoria’s role in bringing a case against Israel to the International Court of Justice further aggravated political tensions, according to the report.

Security rationale vs strategic signalling in naval cooperation

South Africa’s defence department framed the drills around shipping safety and maritime economic activity, without specifying which nations were participating. That language is familiar in the Gulf of Guinea, where governments often justify naval partnerships through anti-piracy and maritime domain awareness rather than bloc politics.

Defence analyst Dean Wingrin, quoted by the BBC, questioned why an economic grouping would stage military exercises, noting that some Brics+ members have deep political differences and even border skirmishes. His point is less about legality than coherence: when coalitions are heterogeneous, military symbolism is interpreted through external rivalries rather than internal agendas.

Domestic politics and foreign policy coherence: a cautionary angle

The report also points to how internal political configurations shape external messaging. Gumede argued that the African National Congress has historically regarded China as an ideological partner and Russia as respected for its support during the anti-apartheid struggle. Yet, after losing its parliamentary majority in 2024 and entering a coalition, he said foreign policy should have been updated to reflect the broader governing partnership.

The Democratic Alliance criticised the exercise. Its defence spokesperson Chris Hattingh said it undermined South Africa’s non-aligned stance because it was led by China and included Russia and Iran, both heavily sanctioned and involved in active conflicts. In his view, hosting such forces could not credibly be described as neutral, even if the government claimed otherwise.

Capability constraints: why exercises still go ahead

Wingrin also offered a practical explanation: years of budget cuts, he said, had left South Africa’s defence capabilities “decimated,” reducing the number of ships able to deploy abroad. That constraint, in his analysis, makes local exercises with visiting navies more attractive, regardless of the diplomatic controversy that may follow.

South Africa’s deputy defence minister Bantu Holomisa dismissed the criticism, saying it was an honour to practise with “well-equipped countries” and that it would boost troop morale. The divergence between morale-building logic and reputational risk illustrates a classic tension in defence diplomacy: readiness and partnerships are tangible, while the cost is often indirect and delayed.

What Congo-Brazzaville can draw from the South African episode

For Congo-Brazzaville, the South African experience highlights the premium on narrative discipline in maritime and defence cooperation. Even when exercises are centred on sea-lane security, external actors may read participation lists as alignment. The lesson is not to narrow partnerships, but to anchor them in transparent objectives, regional mechanisms and economic protection narratives.

It also underlines the importance of calibrating diplomacy to trade exposure. In the BBC account, Gumede emphasised that access to the US market matters and that US-linked economic contributions may exceed China’s in practical terms, while government figures differed on job creation. For Congo-Brazzaville, similarly, economic diplomacy benefits from steady, pragmatic engagement across partners.

Scenarios for African middle powers navigating great-power rivalry

One scenario is “optics management”: shaping participation formats—such as observer status—while keeping operational cooperation on non-controversial themes like maritime safety and piracy deterrence. The News24 detail about Iran’s possible observer role shows how hosts may seek to reduce political friction without cancelling cooperation.

Another scenario is “trade-first pragmatism,” in which governments ringfence commercial relations even as they diversify security ties. Wingrin warned that the exercise itself may not trigger military action, but could complicate trade negotiations because of perceptions. Political analyst Sandile Swana countered that safer seas for international trade should be welcome “by anybody,” stressing anti-piracy logic.

From Mosi to Brics+: How Joint Naval Drills Became Politically Charged

South Africa has conducted naval exercises with China and Russia before. The first, Mosi, took place in 2019 with limited attention. By 2023, Mosi II drew heavier criticism because it coincided with the first anniversary of Russia’s full-scale invasion of Ukraine, prompting questions about timing and political signalling (BBC).

The latest exercise had initially been scheduled for November of the previous year as Mosi III, but was postponed due to a G20 leaders’ summit hosted by South Africa for the first time. It was later rebranded as a Brics+ maritime exercise reportedly titled “Will for Peace,” and the invitation list broadened (BBC).

Timing and Rebranding: A Drill Reshaped by Diplomatic Constraints

In recent days prior to the drill, vessels under Chinese, Iranian and Russian flags arrived at Simon’s Town naval base. The week-long exercise began on a Friday and was led by China, according to the BBC’s reporting.

The exercise’s earlier planned timing—November of the preceding year—was altered due to South Africa’s hosting of the G20 summit. Subsequent rebranding and the expanded participation became part of the broader debate about intent versus perception (BBC; News24 as cited by the BBC).

Key Players and Competing Narratives Around the Exercise

Key actors include South Africa’s defence department, which framed the drills around maritime safety and protection of economic activity; deputy defence minister Bantu Holomisa, who defended the benefits for morale and training; and external partners whose presence shaped the optics: China, Iran and Russia.

Analysts and political voices quoted include defence analyst Dean Wingrin, who stressed optics and capability constraints; Professor William Gumede, who highlighted trade risks and foreign-policy recalibration needs; Democratic Alliance spokesperson Chris Hattingh, who questioned neutrality claims; and analyst Sandile Swana, who defended the anti-piracy rationale (BBC).

Maps and data to watch in Gulf of Guinea diplomacy

A useful map for Congo-Brazzaville-focused readers would locate key naval bases and shipping lanes, mirroring how Simon’s Town featured in the South African story. A second visual could track trade exposure by partner and sector sensitivity, reflecting the BBC’s emphasis on tariffs, job risks and the political economy of foreign policy.

In the BBC account, South Africa’s central bank warned that new 30% US tariffs could lead to around 100,000 job losses, with agriculture and automotive sectors hardest hit. Such data-driven framing shows how defence diplomacy debates increasingly turn on economic risk modelling rather than purely strategic doctrine (BBC).

A measured takeaway for Congo-Brazzaville’s foreign policy toolkit

South Africa’s Brics+ naval drill demonstrates that non-alignment is judged as much by association as by statements. For Congo-Brazzaville, whose diplomacy often prizes stability, predictable partnerships and regional security, the episode reinforces a practical rule: the clearest way to protect manoeuvring space is to align security cooperation with widely shared public goods—safe seas, protected commerce and regional interoperability—while keeping communication consistent and precise.

Above all, the story suggests that Africa’s middle powers are operating in a compressed geopolitical environment where “what the exercise is about” can be less decisive than “what it looks like.” Managing that gap—without forfeiting sovereign partnership choices—has become a core competency of contemporary diplomacy (BBC).
