President Muhammadu Buhari travelled to Equatorial Guinea on Monday for talks with President Obiang Nguema Mbasogo.
The presidents will hold talks on measures to protect the people and resources of the Niger delta and the Gulf of Guinea.
The duo is also expected to sign an agreement for the establishment of a combined maritime policing and security patrol committee on Tuesday.
One most important issue to be discussed will be the rescheduling of the joint summit of the Economic Community of West African States and the Economic Community of Central African States on proactive measures to curb the high security threats posed by terrorist groups.
The meeting will further touch on measures to combat crimes such as piracy, oil rig attacks, crude oil, arms smuggling and human trafficking within their territories.
