Ford Motor’s (F.NYSE) vehicle sales growth in China slowed to 11% in June, down from 14% in May, but robust demand for mid-sized passenger cars pushed up first-half sales 14% year-on-year, MarketWatch reported. Weakening sales growth is due in part to the end of incentive programs instituted by the Chinese government as part of attempts to encourage domestic consumption, but strong domestic economic growth continues to support automobile purchases. The China Association of Automobile Manufacturers forecast 10% growth in the domestic car market for 2011. Ford said yesterday that vehicle sales in China totaled 44,442 units in June and 274,510 units in the first half of the year. It said its Ford Focus model was particularly popular in China, accounting for more than a third of sales. Focus sales rose 19% in June. The firm’s Changan Ford Mazda Automobile joint venture sold 35,929 cars in June, up 19% year-on-year.
