Huawei at Mobile World Congress 2015 Barcelona

The Chinese technology giant, Huawei, has reported revenues of $20 billion for 2015 after a 70% surge driven by phone sales.

Huawei said it sold 108 million smartphones last year, a 44% rise on 2014. That helped it to cement its place as one of the world's largest smartphone manufacturers, behind Apple and Samsung. Earlier in 2015, it reported a 40% rise in sales in the first half of the year alone.

It has been helped by the fact that China is one of the fastest growing markets for smartphones.

However, it has been held back by the fact that areas like its broadband have been banned in the US and Australia over espionage concerns.

Huawei released the figures as it revealed its latest flagship model, the Huawei Mate 8, at the Consumer Electronics Show in Las Vegas. Priced at $644 for the basic model, the Mate 8 is evidence of the Chinese firm's change of stance from producing cheaper handsets to higher end ones in a bid to challenge the likes of Apple and Samsung.
