RT-MART International Ltd. doing business as RT-Mart is a hypermarket chain in Taiwan. Its headquarters are in Neihu District, Taipei. On Thursday December 23, 2004 the company opened its 23rd store. RT-Mart and Auchan made a joint venture, Sun Art Retail Group Ltd. As of September 2012 Sun Art has 12% of the hypermarket share in Mainland China. The stores, which have a more Chinese feel than western hypermarkets, as of December, 2012, are an early favorite with business observers of retailing in the People's Republic of China.   Taiwan-funded supermarket chain RT-Mart outperformed the world's top three retailers in terms of the number of newly opened outlets in China in 2012, according to the National Business Daily in Shanghai. Citing statistics compiled by Linkship.com, a website devoted to serving retailers in China, the newspaper said RT-Mart opened 34 new stores compared to 30 stores for Walmart, 18 for Carrefour and 14 for Tesco. During the same period, RT-Mart did not close any existing outlets in China, an achievement that puts Walmart, Carrefour and Tesco in the shade as they had closed five, two and five stores, respectively. RT-Mart, which bucked the downward trend, is considered a black horse, though its 219 outlets in China makes it the nation's second largest retailer, tied with Carrefour in 2012. Measured by revenue, RT-Mart, which took in 40.4 billion yuan (US$6.4 billion) through its 121 outlets in 2009, ranked first in China that year and eclipsed Carrefour, whose 156 outlets brought in revenue of 36.6 billion yuan (US$5.8 billion). It also holds the record of 330 million yuan (US$52.4 million) in annual revenue for a single outlet in 2009. Additionally, the group posted revenues of 39.41 billion yuan (US$6.25 billion) in the first half of 2012, which is sure to outshine its rivals, reported the National Business Daily.
