--FILE--A pedestrian walks past a department store of Parkson in Changzhou city, east Chinas Jiangsu province, 23 August 2013. Medium- and high-end department store operator Parkson Retail Group Ltd has temporarily closed one of its Beijing stores following two closures elsewhere in the country, adding to a chorus of doubts being voiced about the challenged retail format. The temporary closure by Parkson China - the first foreign-invested retailer in the country, opening in Beijing in the early 1990s - is of its store on the East Fourth Ring Road in the capital city. Earlier this year, it closed a store in Jinan, Shandong province, as well as one in Changzhou, Jiangsu province. Sam Au, chief financial officer of Parkson Retail Group, said the Beijing store is being closed for remodeling and that it will reopen at a later date. He did not give a timetable for the reopening.
