Collaborating with overseas researchers, sharing data, and publishing papers. Routine international cooperation for universities can also pose security risks. The warning from Germany raises serious questions for Japan's research community.

On September 28, 2026, an article by dts News Agency published in BUSINESS-PANORAMA reported that Germany's domestic intelligence agency, the Federal Office for the Protection of the Constitution, warned against the outflow of knowledge and technology through cooperation with Chinese universities.

It is crucial not to simplify this news into a narrative that "Chinese researchers are dangerous." The real question is how well universities can understand and manage the open doors for advancing research.

What are German authorities concerned about?

According to the original article, the agency expressed to the economic newspaper Handelsblatt that China has been building a comprehensive system for transferring technology and know-how. Academic cooperation with German universities and advanced research institutions could become a route for acquiring technology.

The areas of concern include quantum technology, artificial intelligence, hypersonic technology, biotechnology, and surveillance technology. These fields can benefit civilian development and potentially be used for military purposes.

Furthermore, the authorities mentioned legal gray areas and the lack of risk awareness in research institutions, pointing out the possibility that visiting researchers could be used for China's strategic purposes.

However, the original article conveyed a warning about risks from the authorities and did not report any new espionage incidents being proven at specific universities. Blurring this distinction could replace the need for caution with unfounded suspicion of individuals.

"Reading a paper" and "Entering a laboratory" are different

The key to understanding this issue is to differentiate between the publication of research results and access to unpublished information.

Foreign researchers reading published papers is fundamental to academic exchange. However, in joint research, there may be access to data before it becomes a paper, experimental conditions, equipment adjustment methods, and information protected by contracts with companies.

For example, even if a paper showing the performance of a certain material is published, it does not necessarily include all the processes needed to consistently reproduce the same performance. Records of failed conditions also have value in reducing others' trial and error. This is a general example explaining the value of technical information and not a specific case of leakage reported this time.

Therefore, the judgment that "everything can be shared since it will become a paper anyway" is too simplistic, as is the judgment that "if knowledge is transmitted overseas, it is all leaked." It is necessary first to organize what to publish, what to share within the scope of contracts, and what to protect.

The issue of "domestic technology provision" also exists in Japan

For Japanese universities, this issue is not irrelevant.

The Ministry of Economy, Trade and Industry has published materials and case studies on security trade control for universities and research institutions. One such measure is the "deemed export" control, clarified in May 2022.

When thinking of exports, it is easy to imagine sending machinery or parts overseas by ship or aircraft. However, the provision of regulated technology is not limited to the movement of goods. Even domestic provision can become an issue depending on the recipient and the conditions of the transaction.

Understanding this system as "everyone with foreign nationality is treated the same" is also inaccurate. The clarification of operations indicates that technology provision to residents strongly influenced by foreign corporations or governments is also subject to management under certain conditions. The necessity of specific permits is judged based on the content of the technology, the counterpart, and exceptions.

In Japan, the question is not just to list the nationalities of the people accepted but to have a system that can explain which technology is provided to whom and under what conditions.

Voices supporting caution and questioning the crudeness of the debate on social media

Reactions on social media show that this issue cannot be reduced to a simple for-or-against stance.

What was confirmed this time was not the reaction to the original article itself on September 28, but the discussion on Reddit regarding the related news reported in the same month that "Germany rejected many visa applications from China due to concerns about espionage." This is not a public opinion poll representing the views of society as a whole.

In the thread posted on September 12, there were opinions supporting measures, stating that concerns about technology leakage should have been prioritized earlier. There were also voices suggesting that university and faculty partnerships should be reviewed.

On the other hand, there were suggestions that the focus should not be solely on the number of rejections but should include the approved applications as well. Additionally, there were counterarguments that research results are published as papers, and visas are not needed to read them.

These show the coexistence of the necessity for security measures and concerns about the overextension of reporting and regulation. While the speculations of posters cannot be treated as evidence of technology leakage, the need to explain the boundary between public information and information that should be protected becomes apparent.

Japan wants to avoid measures that end with "researchers' self-responsibility"

The Ministry of Education, Culture, Sports, Science and Technology treats research integrity and research security as issues supporting healthy international collaboration. The idea is to ensure academic freedom, independence, openness, and transparency while responding to undue interference and misuse in research.

To make this direction functional on the ground, mere notifications to "be careful" will not suffice. Here are some proposals for Japanese research institutions.

First, at the stage of starting joint research, confirm the affiliation of the counterpart, the source of funding, contractual obligations, and the handling of results and intellectual property. Next, organize the materials that can be made public and unpublished data, and set access ranges according to participants' roles. Also, decide on the handling of accounts and data after the joint research ends.

It is also essential to have a route where researchers can consult with those in charge of export control, contracts, and information management so that they do not have to make decisions alone. If security measures are biased only towards document preparation, it could lead to a situation where important information is not protected even if research time is reduced.

The subjects to be checked should include contracts that Japanese researchers conclude with foreign institutions and joint research with domestic companies. Judging risks based solely on nationality risks overlooking actual funding relationships and access rights.

To continue open research, clarify the scope of protection

What Japan wants to avoid is both losing competitiveness by failing to protect technology and losing cooperation partners due to excessive caution.

If joint research with overseas partners is uniformly stopped, opportunities to combine knowledge, equipment, and human resources will also decrease. Conversely, if contracts and data management checks are omitted under the banner of international exchange, research institutions may not even be able to explain what they have provided.

If Japan is to heed Germany's warning, it is not enough to ask "who to suspect." It is necessary to specifically decide "which information to protect and which knowledge to share with the world."

Can universities understand both the value of the knowledge they publish and the value of the unpublished information they must protect? The responsibility to keep the doors of laboratories open is now being questioned.
