Sensing an opening, Chinese smartphone maker Xiaomi says it plans to enter the U.S. smartphone market in late 2018 or 2019. From a report: The news comes just several weeks after rival Huawei, which appeared to have a head start, had its hopes dashed when a partnership with AT&T was scuttled. While both companies said the parting was mutual, the decision came after intense political blowback from U.S. politicians who worried that Huawei's technology poses security risks for U.S. businesses and customers. Today, the Wall Street Journal reported that Xiaomi chair Lei Jun told one of its reporters: "We've always been considering entering the U.S. market. We plan to start entering the market by end 2018, or by early 2019." In general, while Chinese tech companies have become massive primarily by succeeding on their home turf, they are facing challenges in exporting that success to Western markets.
