Two years after US legislators claimed it was a national security threat, China's Huawei Technologies Co Ltd is planning a campaign to win over US consumers, rolling out new mobile phones and wearable devices backed by a marketing effort.

The Chinese smartphone maker, already with more than $40 billion in annual revenue from a wide range of telecom gear and products, is preparing to introduce Americans to several of its smartphones and wearable devices this year, including its youth-oriented "Honor" phone, Huawei officials told Reuters.

The company's 2015 US plans, which have not been previously reported, will encompass traditional advertising, online promotion and sports team sponsorships, said Huawei's US spokesman Bill Plummer.
