A lot of the issues involving business relations across borders are in fact in the hands of the WTO, which shouldnt inspire any confidence that they would handle them right.
Basically the WTO was set up by the biggest countries economically at the time to protect and facilitate their investment in other countries under terms they wanted at the time. (Special statuses: look up 'National Treatment' 'Most Favored Nation')
Countries where they felt they could extract the highest yields on investments. But the deals are reciprocal and now we have problems in that they made commitments and made countries make commitments which don't work for their people, only for their wealthiest.
These deals commit countries to constantly reduce "non-tariff" barriers to trade (this is called 'progressive liberalisation' and its just totally inconsistent with democratic rule of law on the national level because its invariably things that people do not want.)
Trade barriers as WTO frames them are as often as not good things, not bad, a category that includes basically all the good things that PEOPLE VOTED FOR over the last 100 years. (Everything that protects them from the maxing out of what amounts to a feudal exploitation of the country by corporations)
Thanks to the ever rising power of corporations - the WTO meets every two years to pressure countries to privatize more, to give up more of their social safety nets, irreversibly (there is a ratchet there)
In order to 'justify' this they are insisting that it will help the poor countries corporations as much or more than the rich ones, but that is really debatable. Also is it really wise to prop up dictators with what amount to special concessions for foreign firms (they may get to establish businesses that have much lower costs than domestic firms, which have certain standards they must apply, like paying wages that are many times higher to their workers) Foreign firms simply must pay a 'legal' wage.
Trade barriers are the things that make it possible for families to manage - But they stand in the way of profit maximization- So virtually all - even in the poor countries - they are all supposed to go away to facilitate international trade. (in other words the WTO model has a race to the bottom on things like the hard won improvements in wages and working conditions as well as not discriminating against various groups and safety regs).
Of course they aren't going to rub this in peoples faces so there is a lot of lying going on. Because otherwise people would not be quiet.
For example, in the US the WTO is the real reason the health insurance for people with pre-existing conditions has to be rolled back (to its state 20 years ago, in February 1998) not a very recent federal court decision. Thats going to mean that a lot of people may have to leave the country to find affordable health care. The current system isnt up to the challenge. Same thing in the other wealthy countries. Wages have not kept up with the prices of things like drugs and medical care, which can often bankrupt families.
So basically we're unlikely to be able to figure out whats going on, just from what we read in the news. WTO involvement is much harder to follow.
I have to say though, if Huawei agreed to not share this technology but shared it then they broke a bargain which had been conditional on their not doing that and that is a violation of both US law and contract law which is pretty much the same everywhere.
And the risk of arms proliferation is a serious one.
We made a big mistake by de-emphasizing human rights in the WTO - because thats the area where attention needs to be focused. Setting up an intentionally human rights and labor rights -blind WTO leaves us in a bad position where we have few in the way of ways to stop really bad things. And people everywhere are going to suffer greatly.
The human race may not survive the century because of this stupidity. Because it becomes impossible to encourage improvements in any area when the official line is that they were all impermissible trade barriers, and must be temporary because 'the market' and increased global trade and elimination of rules which raise wages and allow a middle class to exist were all mistakes and now trade is the only permissible solution to all problems and lacks of affordability.
So expect a return to child labor and illiteracy and a sort of dark age of feudalism run and sham politics 'owned' in the worst sense by corporations because thats what the WTO and similar trade organizations and deals are pushing us back to. Of course this is what the oligarchs in the least equal nations want because they are sick of paying taxes to support an infrastructure and population they no longer think they need as business automates.
