A recent report by The Diplomat, referencing a case detailed by Kyodo News, highlights the growing concerns over China’s expanding Anti-Espionage Law, which has significant implications for foreign nationals and international legal norms. The case centers on a Japanese woman detained in 2015 by China’s Ministry of State Security, accused of violating China’s espionage laws by sharing information about the disputed Senkaku Islands (known in China as the Diaoyu Islands) with Japanese officials. The woman was arrested during a business trip to Shanghai, even though the information she shared was not classified as a state secret. Despite this, she was sentenced to six years in prison.
The incident underscores the increasing extraterritorial application of China’s Anti-Espionage Law, which, since its revision in April 2023, broadens the definition of espionage to include a wide range of activities that threaten national security. The law now explicitly allows for the prosecution of acts of espionage committed outside Chinese borders, a move that extends China’s legal reach far beyond its own territory. This approach is based on the “protective principle” under international law, which permits a state to enforce its laws on foreign nationals if their actions threaten the state’s national security, even if those actions take place on foreign soil.
As the report in The Diplomat notes, China’s detention of the Japanese woman—who was apprehended in Shanghai for actions that occurred in Japan—raises critical questions about the extraterritorial enforcement of domestic laws. While the law itself does not violate international norms, the application of such broad jurisdiction beyond China’s borders has sparked concerns among legal experts and foreign governments. The ambiguity of what constitutes an act of espionage under this law—especially activities that do not involve classified information—adds a layer of unpredictability, potentially leaving foreign nationals vulnerable to legal repercussions for seemingly innocuous actions.
The 2023 amendments to the Anti-Espionage Law not only redefine espionage but also enhance the Ministry of State Security’s authority to investigate and prosecute espionage, including acts committed outside China’s borders. This raises the specter of arbitrary enforcement, where activities that do not necessarily harm China’s national security could still be considered espionage, subjecting individuals to potential detention and prosecution.
The law’s extraterritorial reach is already having international implications. Foreign governments and human rights organizations are particularly concerned that it could lead to Chinese surveillance of foreign citizens and organizations, potentially infringing on their legal rights. The ambiguity surrounding what constitutes espionage under this law could also undermine freedom of speech, press, and other basic rights in countries that are not directly involved in the case.
As the Diplomat report highlights, this case is just one example of how China’s approach to national security is increasingly influencing legal practices beyond its borders. The law’s broad interpretation and extraterritorial application could provoke diplomatic tensions, as nations struggle to navigate the fine line between respecting China’s legal claims and upholding the sovereignty of their own territories.
