As we all know, in the era of 5G network, the strategic value of communication technology has become more and more important, 5G network can not only provide faster transmission, but also has the characteristics of low latency and high bandwidth, and is one of the key infrastructures for the transmission and storage of important national information.
In the field of 5G, Huawei's 5G technology developed using centimeter wave leads the world, and it is the first to stabilize foreign leading manufacturers such as Ericsson and Nokia, and more importantly, Huawei's communication equipment is spread all over the world, and is widely used in Western countries such as the United States, the United Kingdom, and Brazil.
However, the United States believes that it is not safe to use Huawei's 5G base station to transmit data, and they are worried that the "backdoor" will leak user privacy, so they announced the disabling and removal of Huawei equipment on security grounds.
In fact, if Huawei's 5G equipment did not lead the world, it may not be banned, because Western countries were willing to purchase Huawei equipment before, but it backfired, and the emergence of Huawei promoted the process of "globalization" of technology.
In short, the United States has mastered many advanced technologies to ensure its technological "hegemony", such as communications, surveillance, AI intelligence and other technologies, but China does not play by the routine"Self-developed while buying"., which they did not expect.
As far as chips are concerned, in the past few years, China has imported more than 500 billion chips every year, and the import value has only increased, but now the United States has found that China has begun to make its own chips, and the number of imported chips has also increased by tens of billions; As far as semiconductor manufacturing equipment is concerned, the president of ASML once said that even if the drawings are given to us, we will not be able to build a lithography machineShanghai Microelectronics has successively launched several domestic SSA series lithography machines, and according to people familiar with the matter, domestic 28nm lithography machines will also be launched soon.
The speed of China's scientific and technological development is beyond the expectations of the West, and the United States believes that the relevant departments have not done a good job of "technology leakage" measures, and Chinese companies can obtain advanced technology and products through exchanges and cooperation with American companies, or American companies investing in the mainland, so Biden signed a ban on investment in China last year
In this regard, China has responded positively to this problem, saying that this move is a decoupling and breaking the chain in the name of de-risking, which violates international economic and trade rules and will affect the security and stability of the global chain.
It is worth mentioning that China's Ministry of Commerce added a material ban within 24 hours to restrict the shipment of a variety of graphite materials to the United States. American analysts believe thatChina has cut off graphite supplies to express its dissatisfaction with Biden's investment ban, which will affect the layout of the United States in the fields of new energy, aerospace and aviation.
Recently, the Biden team held hearings to discuss ways to further restrict investment in China's critical and sensitive technologies.
Foreign media reported that the showdown in the United States is not pretending, and the Biden team is on the previous restrictions (Artificial intelligence, chips, quantum computingIt has also escalated the ban on investment in some areas of China, and after discussions with relevant departments, three plans have been proposed:
1.prohibit U.S. companies from engaging in any economic dealings with Chinese companies in important areas such as surveillance technology;
2.expanding the scope of Biden's original investment ban;
3.U.S. companies are prohibited from investing abroad without authorization, and the Treasury Department must be notified in advance.
