Inside Beijing's Playbook: How China Allegedly Used a Taipei Housewife to Infiltrate Taiwan's Parliament

.

A Naturalized Citizen, a Party List, and Six Years of Secret Reports to Beijing

When Xu Chunying moved to Taiwan from China through marriage in 1998, she built a public identity as a community organizer for Chinese-born spouses living on the island. For over two decades, she led the Taiwan New Immigrants Development Association and was even floated as a potential lawmaker. Now, Taiwanese prosecutors say that entire career was a cover — and that Xu spent years secretly feeding intelligence to Chinese Communist Party (CCP) officials while working to place Beijing-approved candidates inside Taiwan's parliament.

On March 24, the New Taipei District Prosecutors Office indicted Xu on charges of violating Taiwan's Anti-Infiltration Act and a range of financial crimes. The case has sent shockwaves through Taiwan's political landscape — not only because of what it reveals about how Beijing allegedly operates, but because of who Xu allegedly worked with: officials connected to the Taiwan People's Party (TPP), one of the island's main opposition parties.

The Allegations: Loyalty to Beijing, Not Taipei

The indictment detailed Xu's communications between June 2019 and October 2025 with two Chinese officials: Yang Wentao, director of the Service Center for Cross-Strait Marriages and Families under China's Ministry of Civil Affairs, and Sun Xian, deputy head of the Shanghai branch of the Revolutionary Committee of the Chinese Kuomintang.

Prosecutors said Xu explicitly declared her loyalty to the CCP, providing long-term reports on the Taiwanese political landscape to Yang and Sun while participating in election activities under their direction, as well as coordinating a plan to promote the involvement of Chinese-born spouses in Taiwanese politics.

The alleged arrangement was systematic. Xu and her co-defendant, Chung Chin-ming, would travel to mainland China under the stated purpose of assisting cross-strait families — and use those trips to meet with their CCP contacts. She allegedly reported on the daily activities of Chinese spouses in Taiwan, aiding the CCP in monitoring them.

The Target: Taiwan's Parliament

Taiwan's parliament, the Legislative Yuan, has 113 seats. Thirty-four of them — so-called "legislator-at-large" seats — are allocated to political parties based on their share of the popular vote. Candidates are drawn from party lists, and placement near the top of a list virtually guarantees a seat. That system, prosecutors allege, is exactly what Xu was trying to manipulate.

According to prosecutors, Xu shared plans to use Chinese-born spouses in Taiwan as political candidates, which could enable Beijing to cultivate influence directly within Taiwan's political system.

When Xu grew disillusioned with the Kuomintang (KMT) because it refused to nominate Chinese-born spouses for at-large seats, she reportedly told Yang that the KMT "never really wanted unification, it's only fooling Beijing." She then turned her attention to the TPP — a younger, smaller party founded in 2019 by then-Taipei mayor Ko Wen-je.

The TPP Connection

Prosecutors suspect that Xu was instructed by and receiving money from China to support former TPP Chairman Ko Wen-je's 2024 presidential campaign and politician Vivian Huang during her 2022 Taipei mayoral run as an independent. Huang later joined the TPP in 2023.

With instructions to steer a party toward CCP objectives, Xu organized Chinese-born spouses to campaign for Huang to run for Taipei mayor. Although Huang ultimately finished third in that race, the alleged coordination did not stop there.

The indictment also describes how Xu and Sun Xian worked to install another Chinese-born Taiwanese citizen, Li Chen-hsiu, as a TPP legislator-at-large. On March 18, 2024, Xu forwarded personal information about Li to Sun, along with updates on local politics. In a message from August 2025, Sun emphasized that Li must take office regardless of legal challenges — and even outlined a backup plan if she could not.

Li did eventually become a TPP legislator-at-large in early 2026, but her seat has been disputed. Taiwan's government contends that she failed to meet eligibility requirements, including formally renouncing her Chinese citizenship — a step that is legally near-impossible under China's own nationality laws, which do not recognize Taiwan as a sovereign state.

Secret Visits and Forged Documents

Beyond political influence, the indictment contains striking operational details. Prosecutors alleged that Xu facilitated Sun's visits to Taiwan over many years, concealing his government ties through a shell company and falsifying a daily itinerary, which allowed him to secretly meet with KMT and TPP officials.

According to the indictment, Sun allegedly made multiple visits to Taiwan between 2004 and last year, traveling extensively across the island. During those visits, he allegedly met with members of new immigrant groups, claimed to have direct access to Beijing, and encouraged participants to promote the "one country, two systems" framework — the same system that was effectively dismantled in Hong Kong after the 2019 protests.

Xu was also charged with running an illegal underground currency exchange between 2020 and 2025, processing the equivalent of nearly US$900,000.

A Wider Pattern of Infiltration

Academics and security analysts say the Xu case is not an isolated incident but a window into a broader, systematic strategy.

Tunghai University researcher Hung Pu-chao said the case, if proven, would point to a systematic approach rather than an isolated one — with China exploiting legitimate exchange channels and local collaborators to make its activities appear like routine interactions.

The American Enterprise Institute and the Institute for the Study of War noted in a joint analysis that Xu's case closely resembles a prior conviction involving Zhou Manzhi, another PRC-born resident who led civil organizations targeting Chinese-born spouses married to Taiwanese citizens and attempted to recruit them to support the CCP.

A Lawfare analysis by a sitting Taiwanese judge warned that hostile actors frequently exploit legal ambiguities and Taiwan's democratic freedoms, operating under their protection while secretly receiving funding or directives from CCP-linked entities.

A report by the Global Taiwan Institute concluded that no other democracy faces the same scale of foreign threat to its integrity and independence as Taiwan, describing the CCP's influence operations as real and harmful to Taiwanese democratic society.

The Political Fallout

The indictment has landed in the middle of an already volatile political moment. Just days after Xu's indictment, former TPP chairman Ko Wen-je was sentenced to 17 years in prison on separate corruption charges.

The TPP criticized the indictment, arguing that no concrete proof had been made public to support prosecutors' key assertions about Xu's campaign activities. The party has maintained that every citizen deserves the presumption of innocence until a final verdict is reached.

The ruling Democratic Progressive Party (DPP) took the opposite view, with a spokesman arguing the case raised serious concerns about the TPP's ties to Xu and to Beijing, accusing the party of undermining Taiwan's legal framework and autonomy.

Xu has been held in detention since November 28, 2025. Through her legal counsel, she has rejected the charges under the Anti-Infiltration Act, saying that she refused to discuss politics in the chat logs cited by prosecutors, and that her support for TPP candidates was aimed at serving the interests of fellow Chinese-born spouses — not motivated by politics.

The Law Under Pressure

Taiwan's Anti-Infiltration Act, passed in December 2019 and in force since January 2020, bars people from accepting money or acting on instructions from foreign hostile forces to lobby for political causes, make donations, or interfere in elections and referendums.

But prosecutors and legal experts say the law has significant gaps. Many infiltration cases require explicit proof that a specific act was linked to instructions from an external actor — a high bar that is difficult for prosecutors to clear.

China's Taiwan Affairs Office has called the Anti-Infiltration Act an "evil law," and analysts note that Beijing is particularly concerned the law will obstruct its ability to influence Taiwan's upcoming 2026 local elections and the 2028 presidential race.

For now, the Xu case has forced a national conversation about how deep Beijing's reach may already extend — and whether Taiwan's legal tools are strong enough to stop it.
