Taiwan is facing a fast-moving political storm as national security agencies intensify a sweeping crackdown on dual Taiwan–China citizenship cases. What began as a routine administrative investigation has rapidly escalated into a broader debate over national loyalty, legal identity, and how a democracy should defend itself in the face of Beijing’s expanding influence operations.
More than 50 individuals who held both Taiwanese and PRC status have already had their household registrations revoked. The issue then reached local elected offices, where several village and borough chiefs—many of them Chinese spouses—now face removal for failing to renounce PRC nationality.
The controversy soon exploded into the Legislature. The Kuomintang (KMT) caucus introduced a proposal to amend Taiwan’s Nationality Act, seeking to exempt PRC-born spouses from the nationality restrictions that apply to all other foreign nationals. The move triggered immediate backlash from the ruling Democratic Progressive Party (DPP), civil society groups, and national security experts, who warn that the amendment could create a legal loophole for Beijing’s political reach.
Below is a breakdown of the three fronts of this unfolding political clash:
the government’s enforcement actions, the disputes surrounding grassroots public officials, and the legislative battle shaping Taiwan’s democratic defense.

The legal boundary: Over 50 people lose Taiwan status
Taiwan’s rules governing identity—particularly in relation to China—have long been sensitive and complex. As Beijing ramps up incentives for Taiwanese citizens to acquire PRC documents, Taipei has tightened its scrutiny of cases that risk undermining the integrity of its citizenship system.
Over 50 revocations and the cases behind them
According to the Mainland Affairs Council, more than 50 individuals were found holding Taiwanese status while simultaneously possessing PRC identity cards, residency permits, or registration. Under Article 9-1 of the Act Governing Relations between the People of the Taiwan Area and the Mainland Area, those individuals automatically lose their status as “Taiwan Persons.”
The cases illustrate several patterns:
- United front facilitators — such as Lin Jincheng, a senior figure at a PRC-backed entrepreneurship park in Quanzhou, and his associate Su Shien, who allegedly helped Taiwanese citizens obtain PRC IDs.
- Individuals employed in PRC institutions — including Taiwanese academic Zhang Liqi of Huaqiao University, who held a PRC residency permit.
- Political demonstrators — such as taekwondo athlete Lee Dong-xian, who waved a PRC flag at international competitions.
- Single-use cases — people who obtained one-time PRC travel documents for practical reasons but were still deemed to have acquired PRC identity under Taiwanese law.
How authorities identified the cases
Investigations draw from various sources—official checks, public reports, and sometimes even the individuals themselves. Some posted photos of their PRC documents on social media, unintentionally providing evidence for their own deregistration.
A separate set of cases involves Chinese spouses who naturalized in Taiwan but kept PRC nationality for reasons such as inheritance or pension eligibility. Once verified, their Taiwanese citizenship must be revoked by law.
Officials say more cases may follow.
Loyalty and public office: Five Chinese-born local chiefs face removal
The debate intensified when dual nationality issues surfaced among grassroots elected officials—specifically village and borough chiefs who are Chinese spouses.
The Deng Wanhua precedent
In Hualien’s Fuli Township, chief Deng Wanhua was removed after authorities found he had renounced his PRC household registration but still retained PRC nationality. Although he appealed and the county review committee ordered re-examination, the case set a new national precedent.
Four more cases soon emerged in Taipei, New Taipei, and Taoyuan.
Central government: Public servants must have a single loyalty
The Ministry of the Interior has taken a consistent, firm stance. Citing Article 20 of the Nationality Act—“ROC nationals who acquire foreign nationality may not hold public office”—Vice Minister Wu Tang-an emphasized that the rule applies equally to all foreign nationalities, including PRC citizenship.
Authorities instructed local governments to proceed with removals, gave affected individuals a one-year grace period to resolve nationality issues, and warned that inaction could lead to investigation by the Control Yuan.
Interior Minister Liu Shih-fang later reinforced that there are no exceptions and no “affidavit workarounds.” She warned that carving out an exception for PRC nationality would “create special privileges” and undermine democratic norms of loyalty.
The legislative firestorm: KMT pushes to exempt PRC spouses
The conflict escalated sharply after KMT caucus whip Lo Chih-chiang proposed amending the Nationality Act to exempt PRC-born spouses from nationality restrictions.
KMT’s justification
Lo argued that PRC spouses should be governed by cross-strait legislation rather than the Nationality Act, claiming it is unconstitutional to classify PRC nationals as “foreign nationals.”
He framed his amendment as a protective measure and paired it with a proposal to shorten PRC spouses’ naturalization process from six years to four.
The backlash: ‘China privilege’ and national security alarms
The response was immediate and forceful:
- DPP lawmakers said the amendment creates a “China-only privilege” that violates legal equality.
- Taiwan Statebuilding Party criticized it as a step toward treating Taiwan as “China’s internal affair.”
- Commentators said it risks opening Taiwan’s political system to PRC influence.
Several critics argued the amendment would give PRC nationals preferential access to public office—an unprecedented risk in a democracy facing direct threats from Beijing.
KMT’s internal split
Taichung Mayor Lu Shiow-yen underscored divisions within the party, publicly contradicting the caucus by stating that elected officials should hold only one nationality: the Republic of China.
National security warnings: Trojan horses in the system
Beneath the legal debate lies a deeper concern: structural vulnerabilities that PRC nationality could introduce into Taiwan’s security system.
Conflicting legal obligations
Experts note that PRC citizenship carries mandatory obligations:
- China’s National Intelligence Law requires all citizens to cooperate with state intelligence.
- China’s Constitution requires citizens to uphold national unity.
Security analysts warn these obligations are fundamentally incompatible with public service in Taiwan. They also caution that PRC-national officials accused of wrongdoing could claim a legal conflict of obligations as a defense.
‘United front infrastructure’ within Taiwan
Scholars warn that allowing PRC nationals to hold office could embed individuals with exploitable personal, economic, or familial ties to Beijing deep within Taiwan’s institutions.
National security sources note that, in theory, changing the law could make 1.3 billion PRC nationals eligible to run for public office in Taiwan.
The constitutional line of defense
Analysts emphasize that Taiwan’s democracy depends on a clear boundary of loyalty. Past cases involving other foreign nationalities—such as former legislator Diane Lee—were strictly handled, and they argue the standard must be even stricter regarding PRC nationality.
Democratic self-defense and the road ahead
The sequence of deregistrations, contested removals of grassroots officials, and proposed legal amendments has pushed the debate over PRC nationality and political loyalty to the center of Taiwan’s political life.
Taiwan’s Ministry of the Interior and national security agencies maintain that public office requires single and undivided loyalty, and that PRC nationality must be treated as foreign citizenship. They say this is consistent with earlier dual-nationality cases and is essential as Beijing intensifies efforts to influence Taiwan.
The KMT caucus argues PRC spouses should fall under Taiwan’s special cross-strait legislation. But legal experts warn that such carve-outs could shift Taiwan’s legal framework toward a “China internal affairs” logic and erode core protections of its democratic system.
As the dispute moves toward a legislative showdown, Taiwan faces a difficult but unavoidable choice: balancing individual rights with the need to safeguard national security.
To many observers, the KMT’s proposal is no longer just a technical amendment—it has become a test of Taiwan’s resolve to protect its sovereignty and the integrity of its democracy.
