Chinese scientists face difficulties in research, when unable to buy tools and equipment from the US for commercial war.

After the commercial war between the two largest economies in the world broke out in 2018, Chinese scientists said they were more and more difficult in buying research tools from the US.

Chinese President Tap NEW to visit the Institute of Military Science in Beijing in March 2020.

As of December last year, the amount of goods listed on the US control list has increased to more than 4,500.

An artificial intelligence system (AI) has been trained on the database of detailed information about most laboratory tools and equipment across China.

In the past, China was limited to approaching a number of scientific tools because they were concerned that they could be used for military research.

The US government finds ways to limit China's access to a number of foundation and emerging technologies to inhibit China's development in scientific and industrial research, professor Wang Xuezhao with the same

Scientific equipment is one of the few commercial products that are usually not produced in China.

But Chinese scientists need these tools.

Previously, Chinese civilian scientists could get most of the usual tools.

A physicist working in the Chinese national quantum research facility in Anhui city, Hefei province, said their laboratory has ordered research equipment from two years ago, but

We tried to make some tools but could not do everything themselves, an anonymous scientist from Quantum Research Facility in Anhui said.

According to Professor Wang's research, the instruments in the US Export Control List are not separately, which are often related to other tools because of the same technology or field of application.

The connection of these complex relationships can help reveal the potential US strategies, but this is really a challenge to humans.

Research shows that the focus of US export control strategy is the analysis tools using optical or electronic signals to explore the structure of an object or other characteristics.

A remarkable field that the US cannot ban is a measurement device for medical research, which may be completely confident by Washington in this field.

The Chinese government recently launched a series of campaigns nationwide to promote the domestic production science tools, because the dependence on overseas supply has become a threat to national security

But domestic production products are less well received.

According to researchers, by the end of 2019, China has more than 4,000 scientific equipment manufacturers, but mostly produce low-end low-end products.

In some areas such as quantum technology that China is leading, researchers have established private companies to manage equipment because they cannot buy from abroad.

At Hefei, the Chinese government last year spent more than 309 million USD to build a series of consulcuing industrial science tools using quantum technology with the goal of achieving sensitivity and exactly

However, experts evaluating Chinese companies cannot keep up with Western opponents in a short time, because the development of the best scientific tools requires decades of research and experience.

However, experts warn this will be able to lead to division into two scientific blocks in the world, affecting global effort to respond to major challenges.

Scientific research is a front that you just want to keep your knowledge alone, but know if you don't share, you will not know how other people are doing creative and useful things, Caroline Wagner
