More than 400 Taiwanese citizens have been detained, questioned, or have gone missing in mainland China since 2024 [1].
This trend signals a deepening humanitarian and diplomatic crisis as the lack of transparency regarding detainees complicates efforts to ensure the safety of Taiwanese nationals traveling or working across the strait.
According to Taiwan's Mainland Affairs Council, the scale of these disappearances and detentions has grown significantly over the last two years [1]. The agency said the current environment in mainland China makes it increasingly difficult to monitor the status of these individuals.
Officials said Beijing's vague national-security laws are a primary obstacle to tracking those held by state agencies [1]. Because these laws are broadly defined, the Chinese government can detain individuals under security pretenses without providing clear legal justifications or notifying consular representatives.
This opacity creates a gap in information that prevents the Mainland Affairs Council from determining whether these citizens are being held for political reasons or criminal charges [1]. The difficulty in locating the missing individuals further complicates the ability of families in Taiwan to seek legal recourse or demand releases.
While the specific identities of all affected persons have not been released, the number of reported cases exceeds 400 [1]. The situation highlights the precarious legal position of Taiwanese citizens when navigating the mainland's internal security apparatus.
“More than 400 Taiwanese citizens have been detained, questioned, or have gone missing in mainland China since 2024.”
The increase in detentions and disappearances reflects the tightening of security controls in mainland China and the erosion of predictable legal norms for Taiwanese visitors. By utilizing broad national-security legislation, Beijing can effectively isolate individuals from their government and families, using these detentions as a tool of political pressure or intelligence gathering.
