In Issue #3, I used the AFC–Vision Invest–WIOCC transaction to examine a developing Gulf–Africa investment channel. This week, I want to bring that discussion down to a physical project: Dibamba, near Douala, Cameroon.

The connection is real, but it needs to be stated precisely. Vision Invest joined ARISE IIP’s shareholders in September 2025, almost a year before AFC and Vision Invest announced their WIOCC subscription agreement; Dibamba is a project within ARISE’s development portfolio, not a separately disclosed Vision Invest investment (ARISE transaction announcement, AFC’s WIOCC announcement, ARISE’s Dibamba announcement).

For me, that distinction makes the story more useful. It separates the capital relationship we can see from the project-level funding and delivery questions we still need to ask.

Construction of the Dibamba industrial-port development was launched on 24 July 2025, with Prime Minister Joseph Dion Ngute presiding; contemporaneous reporting put the estimated investment at CFA230 billion (Business in Cameroon). ARISE’s own announcement describes a 517-hectare ecosystem developed with the Port Authority of Douala, combining two distinct platforms (ARISE).

•    DDLP, the logistics platform: Planned warehouses, storage facilities and barge transport connecting Dibamba with the existing Port of Douala (ARISE, project announcement).

•    DDIP, the industrial platform: Planned space for agro-processing, wood, minerals, pharmaceuticals and textiles, supported by serviced plots and infrastructure (ARISE).

There is also a domestic institutional-capital connection: ARISE subsequently announced Cameroon’s CNPS as a shareholder in two Dibamba developments (ARISE’s CNPS announcement). This is project-level participation, distinct from the corporate shareholder base described in ARISE’s capital-raise announcement (ARISE).

On 10 September 2025, ARISE announced completion of a $700 million transaction, welcoming Vision Invest alongside AFC, Equitane and FEDA, Afreximbank’s development impact platform (ARISE). The announcement expressly says the transaction included both primary and secondary components, but does not disclose their split or an allocation to Dibamba (ARISE).

That matters when reading the headline number. A transaction combining new capital with purchases of existing shares should not be presented as $700 million of fresh construction funding, much less $700 million committed to one Cameroonian project.

On 1 September 2026, WIOCC announced a signed shareholder subscription agreement under which AFC and Vision International Investment Company would make a combined $300 million investment, supporting data centres, terrestrial fibre and subsea assets (AFC). These are separate transactions involving different investee companies, not evidence that money moved through ARISE into WIOCC (ARISE, AFC).

My reading is that the repeated AFC–Vision Invest relationship supports the channel thesis: investors can build relationships across more than one African infrastructure platform. But a recurring relationship is not a single fund, a guaranteed next deal, or proof that every project beneath a platform has reached financial close.

Dibamba’s July 2025 groundbreaking also preceded ARISE’s September transaction announcement (Business in Cameroon, ARISE). That chronology establishes sequence, not how the early works were financed or whether later capital was assured.

Dibamba connects a capital relationship with a planned cargo route. The graphic distinguishes corporate ownership from project delivery and intended congestion relief.

Graphic sources: [1] ARISE capital announcement; [2] ARISE Dibamba/CNPS announcement and project announcement; [3] Ecomatin.

Dibamba is intended to relieve, not replace, the existing Port of Douala: barges would connect it to new container yards and warehouses beside an industrial park, aiming to ease congestion and accelerate cargo movement toward the hinterland (ARISE, Ecomatin). The developer’s description establishes planned barge logistics, not ocean-going tanker or liquid-bulk facilities (ARISE).

The operating test is straightforward: will the barge-and-terminal chain move cargo more reliably and economically than the route it replaces? I would judge success by cargo dwell time, truck turnaround, total delivered cost and tenant activity, not construction completion alone.

I see two separate tests. The first is whether a developer can attract capable capital partners; the second is whether an individual project can turn that backing into a functioning service.

For a sponsor, I would translate that into three requirements:

•    A defined project: Clear land and permitting status, scope boundaries, cost and schedule assumptions, and responsibility for shared infrastructure.

•    A workable operating model: Identified terminal and transport operators, utility arrangements, cargo demand, and tenant commitments.

•    An explicit risk allocation: Written responsibility for construction interfaces, dredging, maintenance and service performance, rather than an assumption that public shareholding resolves those risks.

I would apply the same discipline to prospective industrial tenants. A location inside Dibamba may offer advantages, but the investment case still needs delivered utility costs, feedstock logistics, lease terms and a credible route to market.

That is the connection I want to draw between the capital story and Cameroon’s opportunity. International backing can strengthen a development platform; the project earns its value when the infrastructure works together and customers use it.

The capital relationship is worth following. The delivery model is worth examining just as closely.
