In recent years, concerns on national security have become an excuse some Western countries used to block Huawei's business expansion.

The latest episode is some media reports on July 19, saying the US and the UK blamed Huawei for security issues again.

In a statement for The Verge, a Manhattan-based technology news website, William Plummer, the vice president responsible for Huawei's external affairs demanded both countries "shut up" if they were unable to put up evidence.

Despite of barriers, Huawei has left remarkable footprints on the way of its international development.

In 2010, Huawei's nearly $21.8 billion in revenues made it the 397th largest company in the Fortune Global 500 list. In 2013, Huawei ranked 315th in the Fortune 500 with revenue of $34.9 billion. It surpassed Ericsson, which ranked 333th with $33.6 billion in revenue, for the first time.

In the global telecommunication equipment market, Ericsson and Huawei, as each other's major rival, contest against each other intensely. Nevertheless, with "cold winter" of telecommunication equipment market at present, the two firms present different trends.

According to the financial reports last year, incomes of the two firms remain the same, but net profit of Huawei was three times than that of Ericsson. At global analyst conference 2013, Huawei revealed that it would achieve annual revenues of $38.9 billion with compound annual growth rate of 10 percent in next five years. It is expected that Huawei would surpass Ericsson to become the world's biggest equipment maker in 2013.

Huawei focuses not only on market share, but also on strategic layout. Enterprise and consumer business will become the main source of motivation in the future according to annual report 2012. The sales revenue of Huawei terminals which include mobile phones, MBB and family terminals was 48.4 yuan in 2012. The production of smartphones which rose by 60 percent was 32 million among these 127 million terminals. What's more, the profit of Huawei experienced a year-on-year growth of 80 percent in 2012.

Obviously, Huawei, which has dominated around half of the mobile broadband market, is developing its mobile phone business through intelligent terminal "east wind".

Yu Chengdong, CEO of Huawei Consumer Business Group hoped that when saying the word "smartphone", consumers can immediately think of Huawei. He also said that Huawei was expected to ascend into one of the top three smartphone brands in 2015.
