Gap Inc, whose portfolio of brands includes Gap, Banana Republic and Old Navy, outlined a strategy to increase total sales to counter lacklustre demand in North America. In China, where Gap opened its first store in November 2010, the company said it would expand from about15 stores at the end of this year to about 45 by the end of fiscal 2012, in late January 2013. The first Gap flagship store in Hong Kong is set to open in a matter of weeks, the company noted.
