In US & EU, dumb ideas occasionally turn into startups, then they show up on crowdfunding (or, worst case, find a dumb VC), and then they die in a fire of varying gloriousness.
In China, the startup happens inside of Huawei instead. The ideas are equally dumb, but they don't die as easily, and when they make it out of Huawei they suddenly have the Huawei name attached and the Chinese government behind it. And it falls to the ITU, IETF, IEEE, or whomever else to shut it down.
Don't get confused by the "Ministry of Industry and Information Technology (MIIT)" there either. This isn't "state driven." They're just different faces of the same large blob.
And it's not about subversion either. They can't do that, yet. If you buy Cisco, Juniper, Ericsson, or Alcatel, and you find a backdoor... you just add it to the list of backdoors. But if you find a backdoor in Huawei, can you imagine the shitstorm that's gonna break loose? They seriously can't afford that. They'd lose not only US & EU sales and influence, but Middle East, African and South American too. They can start doing that in 10 years maybe, but not yet.
