A mainland joint venture between United States casual wear maker Quiksilver and Hong Kong-listed fashion retailer Glorious Sun Enterprises has been delayed for six months due to the Sars outbreak. Glorious Sun Enterprises chairman Charles Yeung Chun-kam said the joint venture would be postponed from September to March next year. The 50:50 venture had planned to open up to 10 stores in Shanghai by early next year. However, Mr Yeung said sales at Glorious Sun's mainland stores, especially in Guangdong province, had picked up to pre-Sars levels this week. But business in Beijing, where the company has 30 stores, is still bleak. Sales fell by up to 70 per cent at the peak of the outbreak, Mr Yeung said. He believed the company would be able to keep turnover this year at the same level as last year.
