Mozambique approved an extended deal for DP World, Grindrod and other operators of its biggest port, including a $2-billion expansion that will further draw cargoes away from neighboring South Africa’s creaking trade infrastructure. The group, which also includes Mozambique’s state-owned railway operator, won a 25-year extension to run the port in Maputo, the capital, ending in 2058. The Council of Ministers approved the deal on Tuesday, according to a statement. The agreement includes investments of nearly $1.1 billion by 2033 when the original concession was due to end.
