Nissan Motor Co expects its luxury Infiniti business to become profitable in three to four years as it begins production in China and introduces entry-level vehicles to attract customers. Infiniti, which last year relocated its headquarters to Hong Kong from Japan, plans to start building cars in China in the third quarter of 2014 and for global sales this year to rise at least 10 percent to about 200,000 units, President Johan de Nysschen told Bloomberg. "We really have been a US-centric brand. The future has got to be for us to look at China," he said.
