China's top minivan maker, Chongqing Changan Auto, said on Monday it is sticking to a forecast of a more than 50% annual rise in first-half profit despite a hit to May sales from the SARS virus, according to Reuters. But the company, which is building a $US98 million car plant with Ford, would not reveal the extent of the hit from the spread of Severe Acute Respiratory Syndrome, the news agency added.
