UPS currently flies to China six times per week. Under a tentative okay granted by the U.S. Department of Transportation (DOT) last week, that frequency could triple, the Atlanta-based delivery service said Sept. 3. UPS said the DOT's decision would give UPS six additional flights to Shanghai immediately and six new flights to Guangzhou next year. It also would let UPS connect Shanghai to Japan with non-stop service and offer non-stop service from the United States to Guangzhou. "This provides an extraordinary opportunity for strengthening commercial supply chains that support growing international trade between the United States and China and throughout the world," UPS Chairman and CEO Mike Eskew said in a statement. UPS entered the China market in 1998 via a partnership with China's Sinotrans. It began direct air service in 2001.
