Seaport operator DP World said cargo volumes at its docks rose 10% in the third quarter of 2011 as trade accelerated at its emerging markets ports.
The world's third-largest port operator said it handled the equivalent of 14.4 million standard 20ft (6m) shipping containers between July and September, up from about 13 million containers over the same period last year.
The Dubai-based cargo handler attributes the gains to growth at ports in Asia, Africa, Latin America and its home market in the United Arab Emirates.
Despite the growth, chief executive Mohammed Sharaf warned that "uncertainty continues to affect the global economy".
DP World manages dozens of ports on six continents, including the Middle East's largest in Dubai.
