Business jumped 16 percent in the first half of the year for Dubai World's global port operations.
The firm is the fourth-largest of its kind in the world and saw gains at ports it operates in Asia, Australia, and parts of Europe.
The company handled the equivalent of 23.7 million standard containers between January and June. That is a significant gain from the same period a year ago when it moved a bit more than 20 million containers.
The company welcomes the growth, which comes after a steep decline in global trade during the economic crisis.
But managers say it is unclear if the growth will continue for the rest of the year.
