The Yenga border dispute between Sierra Leone and Guinea remains a lingering source of tension in West Africa.
Yenga is located in Kailahun District, Eastern Province of Sierra Leone, bordering Guinea’s Forest Region. During the civil war, Guinea deployed troops to aid Sierra Leone against rebel forces and took control of Yenga. After the war, Guinean forces did not withdraw fully, citing security and economic concerns, particularly given the area’s proximity to the Moa/Makona River and lucrative cross-border trade and fishing.
Despite the conflict ending in 2002, Guinea has maintained a presence in the area, leading to unresolved territorial claims and diplomatic friction.

I am attempting to outline possible solutions and offer recommendations to both nations and ECOWAS. I’m also trying to highlight the potential threats if the issue remains unsettled. This is my third article on Yenga, first as an Investigative Journalist reporting for an international news outlet in 2011 and the second was to urge Sierra Leone’s newly elected President (then in 2018) His Excellency President Dr. Julius Maada Bio. Note that views expressed are exclusively mine.

Indeed, several bilateral talks have taken place, with occasional promises of troop withdrawals and demarcation efforts, but no comprehensive, lasting solution has been implemented.

As a Development and Judicial Communications expert, let me propose the following:

  1. Bilateral Border Commission Revival

Establish a permanent Sierra Leone–Guinea Border Commission, with legal and technical experts from both sides, to oversee demarcation, conflict resolution, and joint development initiatives in disputed areas.

  1. Independent Geographical Survey

Commission a neutral third-party, preferably under the African Union or ECOWAS, to conduct a thorough historical and geographical survey of the border, using colonial maps, treaties, and international law as references.

  1. Joint Economic Zone

Create a cross-border economic cooperation zone in Yenga, enabling shared control and mutual benefit from the area’s resources, especially fishing and trade, under joint administration.

  1. Community-led Dialogue

Involve local leaders, traditional authorities, and civil society from both countries to build trust and promote peaceful coexistence through grassroots diplomacy.

I have visited Yenga twice and therefore let me recommend to the Governments of Sierra Leone and Guinea:

Recommit to diplomatic engagement and renounce any military presence or action in the disputed area.

Invest in infrastructure and services in the border regions to reduce tension and improve livelihoods.

Collaborate on security to prevent transnational crime without territorial infringement.

To ECOWAS:

  • Mediate and facilitate high-level talks between both nations, ensuring neutrality and consistency in the peace process.
  • Provide technical and logistical support for border demarcation.
  • Enforce compliance through diplomatic channels and, if necessary, sanctions or regional court rulings.
  • Encourage donor agencies to support joint development projects as confidence-building measures.

If the Yenga issue is not settled amicably, it could:

Erupt into armed conflict, destabilizing a region already vulnerable to insurgencies and extremism.

Undermine regional integration efforts and economic cooperation under ECOWAS frameworks.

Exacerbate nationalistic sentiments, damaging long-standing diplomatic relations and people-to-people ties.

Provide a breeding ground for illicit activities such as smuggling, arms trafficking, and illegal mining.

In conclusion, the Yenga border dispute stands as a test of diplomacy, regional cooperation, and the commitment to peace in West Africa. Sierra Leone and Guinea must seize the opportunity to resolve the issue definitively, with ECOWAS playing a proactive and impartial role. Peaceful resolution will not only benefit both nations but also serve as a model for resolving border disputes across the continent.
