The South China Morning Post published on 21 May 2024 an article titled "After Talks with China, Benin Eases Oil Export Ban against Niger."
Benin allowed a shipment of crude oil that arrived by a Chinese-built pipeline from Niger to depart for China following discussion with a delegation from state-owned China National Petroleum Corporation. China has considerable economic leverage with both countries and likely used it to end their dispute, thus allowing the oil to depart by ship.
