Hyundai Motor's plans to expand production in China appear to be gaining fresh momentum with two Chinese cities - Chongqing and Cangzhou - being cited as possible venues for its fourth and fifth plants. "Along with the fifth Chongqing plant, the company is newly considering renovating an existing plant in Cangzhou to build its fifth plant in China," a ranking Hyundai executive was quoted as saying by a local newspaper on Wednesday.
