Taiwan Sounds the Alarm: TikTok, WeChat, and the Chinese Data Threat

In this episode, we examine Taiwan’s growing alarm over Chinese mobile applications, especially TikTok and WeChat, in light of rising global concern over data privacy and foreign surveillance. A recent inspection by Taiwan’s National Security Bureau (NSB) revealed that these apps aggressively collect personal data and transmit it to servers located in mainland China—where national laws require that user data be made available to Chinese government authorities upon request.

Taiwan’s warning isn’t isolated—it echoes fears expressed by governments across the world, from the United States to India to European regulators, who see apps like TikTok, WeChat, and others as national security risks. At the center of this debate lies the Data Security Law (DSL) of the People’s Republic of China, a sweeping mandate that compels companies to store data within China and hand it over for national intelligence purposes. Taiwan’s NSB highlighted violations such as the unauthorized collection of facial recognition data, contacts, geolocation, and more—actions that could be leveraged for foreign surveillance, espionage, or influence operations.

We explore:

• The mechanics of data collection by TikTok, WeChat, and similar Chinese-developed apps—including how these apps access sensitive personal information far beyond what's needed for their core functionality.
• How Chinese national laws—especially the DSL, Cybersecurity Law, and National Intelligence Law—enable state access to user data stored by any company operating in or connected to China.
• Taiwan’s broader national security context, including cyberattacks and espionage targeting its infrastructure, which raise the stakes for data security.
• Parallel concerns from other nations, including EU investigations into unlawful data transfers, India’s outright bans on hundreds of Chinese apps, and ongoing U.S. debates about TikTok's fate.
• The potential for foreign influence through content curation, especially via algorithmic targeting of political messages and behavioral profiling enabled by biometric data collection.
• Regulatory dilemmas facing democracies: how to balance free markets and open technology with the imperative to protect citizens’ data and national infrastructure.
• Taiwan’s alignment with global trends in confronting China-developed software—not just through advisories but also through technological countermeasures and increased cyber resilience efforts.

The episode also covers what average users can do: re-evaluating app permissions, avoiding features with poor transparency, and understanding the geopolitical stakes behind seemingly innocuous mobile platforms.
