USA has justified all its "sanctions" by "national security concerns".
However, what matters are the actions, not the words. The US "sanctions" had major effects on the markets for various consumer products and on the profits of certain companies, but they had little or no effect on anything that truly matters for national security.
Attempting to prevent Huawei from making smartphones has absolutely no relationship with the US national security.
Forbidding the use of Huawei communications equipment in critical infrastructure has absolutely nothing to do with the US "sanctions". Choosing what to buy is an internal matter of USA or of any other country that institutes such regulations and only incompetents will use in critical infrastructure black boxes that may be controlled by another country.
Trying to equate a measure taken against the world and in favor of Qualcomm, by sabotaging the production of smartphones at Huawei, with an internal regulation like forbidding the acquisition and use of Huawei equipment for infrastructure, is a logical fallacy. Only the second of these 2 is justified.
> Would you be in favor of ASML being able to license out its technology to China?
ASML is free to license its technology as they please, but obviously they would be very stupid to do so.
More than twenty years ago, Huawei entered the smartphone market by licensing the technology for making smartphones from Siemens. Siemens sent engineers in China, at Huawei, who stayed there for a half of year or more, to teach the Huawei engineers how to make smartphones.
Already at that time, I considered what Siemens was doing as being incredibly stupid. Of course, a few years later Huawei was making better and cheaper smartphones than Siemens, while Siemens decided to abandon the smartphone market. All that is the fault of the management of Siemens, not of anyone else. The worst part was not the licensing of the technology, even if that was very dumb, but the incapacity of the management to prioritize the continuous improvement of their products, both by becoming better and by becoming cheaper, while Huawei was very motivated to do this, so starting from at most the same position they still pulled far ahead.
I have seen plenty of companies which were forced to abandon markets, or went bankrupt or were acquired by competitors, and which blamed their fate on supposedly unfair competitors, e.g. from China. But in all those cases I have never seen any attempt from those companies to really compete. All were complacent to have products that were successful in the past and now they were making only negligible changes to them, especially from the point of view of the production costs, hoping that those products will continue to make money forever, even without any significant improvements.
I hope that the European car industry will survive, but if anything happens to it it will be only due to mismanagement, not due to China, because what should have been done to make competitive electric cars was known for decades and in Europe there was more expertise in power electronics than anywhere.
You accuse me of being in favor of things that directly contradict what I have said in my first comment.
I have already said that one of the things that I dislike at USA is that it has fought for decades to dismantle all protectionist barriers in all countries, to enable US companies to sell more there, which has lead to the destruction of many local industries. Now USA feigns forgetting all what has been said and done in the past, while trying to implement trade barriers.
I have also already said that I consider the availability of locally-produced goods, to avoid excessive interdependencies, more important than the lower price that could be achieved when all the production for the entire world of a certain item would be concentrated in a single giga-factory.
But protective measures must be chosen wisely. As long as there is no local production, there is nothing to protect. And also, if local production is protected from competition, there must exist alternative legal means to force them to design and fabricate competitive products, instead of exploiting the privilege of being protected.
Until I will see the resurrection of the European industries of memories and of smartphones, I would prefer to buy them cheaply from China, instead of being forced by the actions of the US government to buy them at triple prices from Micron and Qualcomm.
