The presidents of Guinea, Liberia and Sierra Leone are set to meet on Monday for a summit following recent border tensions, a day after Conakry deployed troops to its frontier with Liberia.

The meeting, to be held in Conakry and led by Guinea's President Mamady Doumbouya, comes amid disputes between the country and its two neighbours regarding the contours of their respective territory.

Liberian leader Joseph Boakai and Sierra Leone's President Julius Maada Bio are due at the closed-door summit.

Côte d'Ivoire, which shares a border with Guinea, is also expected to attend as a "witness country."

Guinea deploys troops

The four nations are members of the Mano River Union, an association aimed at facilitating free trade, infrastructure development and bolstering security in the Mano River basin.

Guinea deployed troops to its border with Liberia on Sunday, according to images released by the military's press office.

The images show a convoy of military vehicles, pickup trucks and armoured vehicles parked in front of a military camp, along with heavily armed soldiers.

Doumbouya is seen presenting them with the national flag before their departure.

Liberia urges calm

"I, Mamady Doumbouya, assure the people of Guinea that no portion of the land bequeathed to us by our ancestors will be conquered by anyone", he said, according to the military press office.

Doumbouya, who came to power in a 2021 coup, was elected president in late December 2025.

On Thursday, the Liberian government called on its citizens living along the border with Guinea to remain calm and avoid escalation, after tensions flared and left one person injured.

In late February border incidents also occurred between Guinea and Sierra Leone, with both sides alleging that military officers from either side crossed the frontier.

Sierra Leone additionally said Guinean troops had detained its soldiers and police for several days after clashes.
