Apparel maker Tri-Star Ltd has hired 800 additional staff for its second factory, set to open next month.

The Ugandan company, which exports primarily to the United States, said 470 of the new workers had already completed a two-month training course while the remainder were still at the company's training institute.

"Because we had limited capacity, we couldn't meet all the demand," CEO Villupilai Kananathan said of the decision to open a second plant.

"Now, with additional labour force, we should be able to satisfy the demand in the US market."

By end-May, the facility is expected to employ 2000 workers.
