la réponse du GT chinois: https://www.globaltimes.cn/content/1197211.shtml

je résume: "ce n'est pas Clean la ou les US ne peuvent se brancher pour espionner/pomper les données".

Clean carrier, the first line of effort, aims to ensure Chinese carriers "are not connected with US telecommunication networks" to prevent US national security threats. The Trump administration suspects that Chinese companies, including Huawei, would gather intelligence in the US through 5G base stations. In fact, such suspicion derives from the US' own surveillance practices. 

When it comes to telecom theft, the US always ranks the first in the world. In addition to pressuring the AT&T, Verizon and other carriers for data supplies, the National Security Agency (NSA) has been using fake base stations named Dirtbox in its wiretapping programs including the Boundless Informant since a decade ago. Through Dirtbox, they simulate signals of base stations to tap into and steal data from cell-phones. Le Monde wrote that thanks to Dirtbox, 62.5 million phone data were collected in France.
