Hariri assumed the leadership of Mawani in July 2021. Mawani supervises Saudi Arabia’s ten ports across the Red Sea, the Arabian Sea, and the Arabian Gulf. In October 2023, the company and Saudi Global Ports announced a deal to build a logistics park spanning over a million square meters at King Abdulaziz Port in Dammam, with an investment of around $266.7 million. Mawani is currently increasing the port’s capacity to reach more than 40 million standard containers and upscaling the kingdom's share in the transshipment market to 45%. Hariri was previously CEO of Saudia Cargo and Saudi Arabian Logistics (SAL).
