Volvo Car Corp, the Swedish unit of Ford Motor Co, aims to double its market share in China from 3% to 6% by selling 20,000 vehicles annually over the next five to six years, a near sevenfold increase over the 3,000 vehicles sold last year, Ong Eng Seong, president of Volvo Car China, told China Daily. While competitors trimmed their selling prices to revive weak demand, BMW by as much as 14%, Volvo maintained its prices, selling 1,000 units in the first quarter this year, up 25% over a year ago. Volvo, which plans to sell 2,500 more by year-end, sells only imports now but is considering starting production in China.
