As automobile sales spread inland from China’s crowded east coast cities and automakers boost capacity in the west of the country, companies that move cars and spare parts by truck from factories to showrooms are expanding to meet the demand.

Nippon Yusen, the world’s largest carrier of vehicles by sea, plans to add more logistics centers for trucks in China. Anji Automotive Logistics, a unit of China’s biggest carmaker SAIC Motor Corp., will expand the construction for collecting and distributing autos, according to its Web site.
