Eight of the top ten smartphone vendors in China are Chinese

"In Q2 2014, the world’s largest smart phone market, mainland China, accounted for 37% of global shipments – some 108.5 million units. Of the top five vendors in China this quarter, all but one were local companies. And perhaps more impressively, that home-grown success continues in the top 10, where eight vendors were Chinese. In little over a year, Xiaomi has risen from being a niche player to become the leading smart phone vendor in the world’s largest market, overtaking Samsung in volume terms in Q2. Xiaomi took a 14% share in China, on the back of 240% year-on-year growth. With Lenovo, Yulong, Huawei, BBK, ZTE, OPPO and K-Touch, the eight Chinese vendors in the top 10 together accounted for a total of 70.7 million units and a 65% market share. Samsung and Apple, the only international vendors in the top 10, together accounted for shipments of 20.0 million units, representing 18% of the overall smart phone market in China."
