Re: No laws?
"We" is his employer "HUAWEI TECHNOLOGIES (UK) CO., LTD." which is on this side of the HCSEC firewall.
There are no laws in China that can compel "HUAWEI TECHNOLOGIES (UK) CO., LTD." to break the law in the UK, because that company must comply with UK law. This has the hilarious effect of being technically correct whilst at the same time having absolutely no effect whatsoever on the legions of spies that work for the Chinese government - that is what the HCSEC is for. HCSEC fulfils the role of being a deterrent to overt backdoors. In other words - the reason they haven't found any backdoors may very well be because they are looking for backdoors.
If Huawei does indeed play host to Chinese government spies, this still does not constitute an actual request from the Chinese government - it is easily possible for the Chinese to attempt to conduct intelligence operations without involving the company's executive branch and in fact any covert operation would only be hindered by a request to the company as any such request that the UK branch of the company became aware of would result in GCHQ being immediately notified of the request, blowing the whole thing open and permanently ruining it for the Chinese. So you can bet your ass that the Chinese are not going to make any such request.
The success of any Chinese intelligence operation therefore depends solely on the effectiveness of covert intelligence and UK counterintelligence operations, of which Mr John "I used to be HMG's CIO" Suffolk is a part. Having occupied such a sensitive position in the government he must continue to comply with the requirements set by his HMG security clearance until the day he dies. I would be very surprised if it is even possible for him to cut ties to the UK intelligence services - if he did so, I expect that he would quickly find himself committing suicide by chopping himself up, bundling himself into a sports bag, and throwing himself in the river. In short, Huawei's Global Cyber Security Officer is a de-facto GCHQ informant.
It's a very strange relationship between two countries where extreme mutual distrust has had to coexist with an extreme mutual desire to make money. Ironically enough Huawei products are probably safer from deliberate backdoors than those of any other provider, specifically as a result of this scrutiny. I would say there is a case to be made for subjecting all equipment providers to similar levels of scrutiny but that would be very expensive.
Or maybe we could just build our own telecoms gear?
