After the incident, when a foreign company made an acquisition in the United States, it was required to report the transaction to the Committee on Overseas Investment (CFIUS), but Huawei did not report it many times and conducted the transaction privately. As a result, when acquiring 3leaf this time, CFIUS sent Huawei a proposal to abandon the transaction.
Huawei rejected the proposal and called on Obama to make a decision.
If Obama says Huawei should invest, he is saying that the national security adviser (CFIUS) he hired is an idiot. If Obama says Huawei should give up, it will anger Beijing. (In fact, Huawei's practice is a bit impolite. = )
However, Huawei is always secretive about its work and has private contact with China's military. Moreover, the whole world has gone everywhere to buy it, and now it has gone to buy a telecommunications company in London, England, without explaining the source of funds. It's easy to suspect.
