China says 4 American airlines missed Taiwan deadline

Chinese regulators appear to have rejected a possible attempt by US airlines at a compromise over Beijing's demand to call self-ruled Taiwan a part of China, an order Washington opposed. The communist mainland's latest effort to use China's growing economic clout to isolate Taiwan's democratically elected govt is further straining ties between Beijing and the US amid a deepening trade dispute. The Chinese airline regulator says United Airlines, American Airlines, Delta Air Lines and Hawaiian Airlines missed a Wednesday deadline to change their websites while 40 other carriers obeyed. The US carriers had hoped that listing Taipei without a country would be good enough because Korean Air took a similar approach. Korean Air, however, began changing its website far ahead of this week's deadline. <br/>
