Shenzhen-based ZTE's smartphone shipment to the U.S. Jumped more than 50 percent in 2014, outpacing the company's global smartphone shipment growth of 20 percent as it aims to become a top three smartphone vendor in the United States by 2017.

The company ranked No.4 in the U.S. handset market in the first quarter.
ZTE has been expanding its smartphone business overseas as it looks to become one of the top global handset manufacturers  amid a slowdown in smartphone sales at home and the rise of domestic rival Xiaomi Inc.
An aggressive marketing campaign in the United States, including being the official smartphone sponsor of three U.S. National Basketball Association teams, boosted shipments last year. Cheng said they would add to this in 2015 by forging a new partnership with at least one more NBA team.
