By Chong Koh Ping The New York Stock Exchange will delist China s three large telecommunication carriers, following a U.S. government order barring Americans from investing in companies it says help the Chinese military. This will result in China Mobile Ltd. which is among the most valuable of China s listed state-owned enterprises being kicked off the Big Board after more than two decades, after the privatization of its predecessor in 1997. The NYSE decision is the latest setback for U.S. investors in these companies, which rank among the largest global telecommunications providers but have lagged behind the broader markets since the companies began listing here more than two decades ago.
