[$$] American Hustle: ZTE’s Surprise U.S. Success, Now Under Threat

HONG KONG—In the five years since ZTE Corp. was branded a national security threat by U.S. lawmakers, the Chinese telecommunications giant has been quietly building its own American success story. While locked out of the market for networking technology, ZTE has expanded its smartphone business to where it is now the fourth-largest among U.S. consumers. Last year the Shenzhen-based company almost doubled its market share to 11.2%, selling 19 million handsets and making the U.S. its biggest market, according to research firm Canalys.
