US still seeking hegemony in cyberspace
According to the latest documents revealed by former US National Security Agency contractor Edward Snowden, the NSA has spied on several former Chinese leaders, multiple government departments and banks, with China's telecom giant, Huawei, being a core target for the NSA's snooping in China.
Chinese leaders' official communications and the internal information of various Chinese government departments should be classified as China's state secrets, and as such protected by Chinese law. In the information age, they also belong to China's information sovereignty. The United States is well aware of this, as Washington has been heavily criticizing China for the same reason, claiming Chinese-based hackers have infiltrated US government and company networks.
Even when it comes to its company information, the US regards it as a jewel of the greatest value. Protecting the country's intellectual property rights has become a sacred mission of the US government. So, protecting the country's information sovereignty, especially protecting its state security confidentiality has become the highest duty of the US government.
