Japan’s Nissan plans to double its production capacity in China to 1.2 million units by 2012, as it aims for a 10% share of the world’s biggest auto market. The new plan is 20% above Nissan’s earlier target. Nissan, 44% held by France’s Renault SA, operates in China wih Dongfeng Motor Group, which has just announced the opening of its first sport utility vehicle (SUV) plant in the central city of Zhengzhou. "Among the Japanese carmakers, which represent 20% of total sales in China, Nissan holds the number one position. We believe we have the potential to earn a higher market share through our partnerships with Dongfeng and Zhengzhou Nissan," Chief Executive Carlos Ghosn said at the opening ceremony for the new SUV plant. The Wall Street Journal reports that Nissan is now the top-selling Japanese automaker in China.
