HSBC Holdings Plc, Europe's biggest bank by value, is talking with Chinese regulators about selling shares in the country. "There have been discussions held with the relevant authorities on the potential listing on the Shanghai Stock Exchange," Vincent Cheng, HSBC's Asia-Pacific chairman, told reporters in Hong Kong. "There isn't a timetable" for a stock sale, he said. China said last week it will let foreign companies sell stock and bonds in the nation for the first time.
