As technological competition grows increasingly intense, technological security has become an important area of national security. Once sensitive scientific research data is leaked, it may not only affect the future prospects of researchers themselves, but also potentially endanger national security, read an article by the Chinese Ministry of State Security (MSS) on Wednesday.

A casually disclosed update on research progress, or the upload of unauthorized materials — such "unintentional mistakes" may well lead to the leakage of scientific research information, therefore requiring serious attention and prevention, the article warned.

The article cited one case as an example. In order to increase the chances of acceptance when submitting papers to international journals and academic conferences, a researcher, without undergoing the required confidentiality review by his or her institution, included detailed information in the appendix and supplementary materials, such as the core structure of equipment, key technical parameters, and distinctive experimental sample data. This resulted in the leakage of important technical details, and the individual concerned as well as relevant responsible personnel were held accountable, according to the article.

Another case showed that a staff member from a domestic university, while conducting a visiting study overseas, stored sensitive data including unpublished raw experimental data and interim research parameters, on an overseas cloud drive and in a personal overseas email account for research convenience, without completing the required confidentiality approval procedures for the cross-border transfer of research data. 

A foreign partner institution obtained core scientific research information through backend extraction and published related academic findings ahead of others, resulting in the loss of value of domestic research achievements. The individual concerned and relevant responsible personnel were held accountable, the MSS article wrote.

The MSS article also warned of photo-sharing leaks. In one case it provided, some university students and researchers casually took photos of experimental scenes, instruments and equipment, and new devices while conducting experiments in laboratories, operating precision equipment, or testing experimental platforms, and then post them on online social media platforms. 

These seemingly ordinary daily-life posts may be captured by foreign espionage and intelligence agencies or relevant research institutions, which may analyze them to identify sensitive information such as equipment performance, technical shortcomings, experimental conditions, and research progress, creating risks of leaks and disclosure.

Another case showed that some researchers, when attending overseas academic forums or online seminars, lack sufficient vigilance against targeted technical questions, data inquiries, and probing into research topics raised by foreign participants, and casually disclose key details such as technical principles and process flows. Such remarks, made in passing, may become high-value intelligence for foreign espionage and intelligence agencies or relevant research institutions.

Strictly observing confidentiality requirements in scientific research and building a strong line of defense are essential, the MSS article underscored.

A small number of New Zealand lawmakers recently ignored China's serious concerns and firm opposition and insisted on visiting China's Taiwan region. Their actions violated the one-China principle and interfered in China's internal affairs. In accordance with the relevant laws of the People's Republic of China, China has decided to impose entry-ban measures on the individuals concerned, Chinese Foreign Ministry spokesperson Mao Ning said on Thursday in response to a question about China's one-year entry ban on four New Zealand lawmakers who previously visited Taiwan. 

"I would like to emphasize that the one-China principle is a widely recognized norm of the international community and a basic principle governing international relations. It is also the political foundation of China-New Zealand relations," the spokesperson said. "We urge the individuals concerned to genuinely respect China's sovereignty and territorial integrity, and strictly abide by the one-China principle. Anyone who crosses the line and violates China's core interests on the Taiwan question will inevitably pay the price," Mao noted. 

In response to another media inquiry that some German lawmakers visited Taiwan region in May and whether China would ban lawmakers from Germany and other countries who visit Taiwan region from entering China, Chinese Foreign Ministry spokesperson Mao Ning stated that Taiwan is a part of China, and that the one-China principle is a prevailing consensus of the international community, a basic norm governing international relations, and the political foundation of China-Germany relations. 

Mao said it is hoped the German side will abide by the one-China principle and refrain from interfering in China's internal affairs by using the Taiwan question, adding that "anyone who crosses the red line on the Taiwan question will definitely pay a price."

On May 29, following the keynote address and opening dinner of the 23rd Shangri-La Dialogue, Japan’s Defense Minister Shinjiro Koizumi was surrounded by reporters. A Global Times reporter on the scene asked Koizumi when the Japanese government will retract erroneous remarks on Taiwan island made by Sanae Takaichi. Faced with the question, Koizumi maintained a serious expression and dodged the question with silence, leaving the dinner venue surrounded by his entourage.

In November 2025, Takaichi openly declared in a Diet meeting that a potential contingency in Taiwan region could constitute a "survival-threatening situation" for Japan, implying the possibility of armed intervention in the Taiwan Straits. To this day, the Japanese side has not only failed to retract the erroneous remarks but has also taken a series of moves that have further heightened regional tensions. China’s Ministry of Foreign Affairs has issued repeated warnings: Japan’s neo-militarism spreads rapidly and dangerously, which has already posed a real threat to world peace and stability.

At the Chinese Foreign Ministry’s regular press conference on May 29, a reporter raised a question regarding reports that, “according to data recently released by the Japanese government, orders from the Ministry of Defense have tripled over the past five years, making up half of the government’s public procurement orders in fiscal year 2025, as a result of Japan’s policy to bolster defense capabilities.

Chinese Foreign Ministry spokesperson Mao Ning said that the reactivation and rapid rise of Japan’s military industrial complex represents another major development in Japan’s accelerating remilitarization. Does Japan intend to return to the path of militarist expansion? All peace-loving people in the world, including the Japanese people, must stay on high alert, Mao said.
