The economic pulse between the two largest world powers has led to a great shake-up in the global technology business. The United States has included the Chinese cellphone and tablet giant Huawei, which it considers a danger to national security, on a blacklist that, in practice, prevents US firms from selling components or software. The first big consequence has come with breakdown of the business with groups like Google or Qualcomm, which leaves millions of consumers restless. When two elephants fight, the grass underneath suffers. Nothing like Huawei embodies China's challenge to the Western economic powers, the voracious growth that this company represents and also all its chiaroscuro. Founded 30 years ago, the firm has become the first manufacturer of technological products in the world and the second largest seller of mobile phones, second only to the Korean Samsung. Last year it gained 59.3 billion yuan (about 7,850 million euros), which is an increase over the previous year of 25%, thanks mainly to the push of billing, something very difficult to achieve in a mature company. Success, however, can not be abstracted from habitat. The Chinese Communist Party (CCP) regime, with its open support for local versus foreign companies, is preparing a process of technological self-sufficiency that can now be accelerated.
