DOHA, Qatar (AP) — Qatar says it will make critical investments in a $3.7 billion oil refinery project in Egypt that’s among the biggest economic initiatives since the 2011 fall of Hosni Mubarak.

Qatar’s minister of energy and industry, Mohammed bin Saleh al-Sada, did not give the specific amount of the Qatar share, but previous reports from the wealthy Gulf state estimated at least a $400 million initial investment to help launch the long-stalled project.

Egypt’s Oil Minister Usama Kamal said Saturday the refinery on the outskirts of Cairo will produce 4.2 million tons per year of gasoline, diesel and other energy products.
