Sorry, but I highly doubt Huawei's helping in anything here. But maybe, the 5G from China has not been "weakened" on purpose by the US. That said, it does not matter much nowadays, since most are communicating via E2E apps. Which, means, the "monitoring" has been force to happened at the app layer more than at the LTE/5G layer.

Not sure. Huawei has reconstructed everything from satellites to signal base station transmission to mobile phone terminals and operating systems. Previously, the world's important heads of state, the presidents of the European Union and NATO, were all under the surveillance of the US government. Basically, their foreign policies and ideas are transparent. They can always know all the news in advance and make timely response policies. Everything is under their control. But you will find that in recent years, more and more hostile countries have suddenly begun to establish diplomatic relations. The US government did not monitor any news in advance. These are beyond the expectations of American politicians. This situation should be more common in the future.
