Daimler, the world's leading truckmaker, expects commercial vehicle markets in developed countries to rebound only slowly while major growth comes in emerging markets, a top official said.

Daimler Trucks Chief Executive Andreas Renschler told reporters he expected all the group's truck units to be profitable this year.

Amid tough competition from Chinese rivals, Daimler's share of the global truck market fell to 11 percent last year from 15.2 percent in 2008, the company said on Wednesday.

Its unit sales shrank to nearly 211,000 vehicles from nearly 330,000 the year before.
