The Long Reach of Beijing: Inside the Transnational Repression Plot Against an American Olympic Star and Her Father

On November 16, 2021, Matthew Ziburis, a veteran of both the U.S. Army and the Marine Corps with service history in Iraq, sat in a parked car in a quiet Northern California neighborhood. His objective was what he termed an "enemy"—a description that masked the reality of his targets: Arthur Liu, a California-based attorney, and his teenage daughter, Alysa Liu, who was then one of the world’s premier figure skaters. This surveillance operation, conducted on American soil against American citizens, was not the work of a rogue private investigator, but rather a coordinated effort orchestrated at the behest of the Chinese government.

Arthur Liu’s life story represents a classic arc of the American Dream, albeit one forged in the crucible of political upheaval. As a university student in China, he participated in the 1989 pro-democracy protests. Following the violent crackdown at Tiananmen Square, Liu fled to the United States, eventually settling in the Bay Area to practice law. He dedicated his resources to supporting his daughter’s meteoric rise in the world of figure skating. By age 13, Alysa Liu was a national champion, a frequent guest on late-night television, and a heavy favorite to represent Team USA at the 2022 Winter Olympics in Beijing. It was this intersection of political dissent and high-profile athletic success that placed the Liu family in the crosshairs of Beijing’s Ministry of State Security.

The Mechanics of Transnational Repression

The stalking of the Liu family was part of a broader, more sinister phenomenon known as transnational repression. This refers to the efforts of authoritarian regimes to silence, harass, or intimidate dissidents and their families living abroad. In the case of the Lius, the operation involved a multi-layered network of operatives. According to federal indictments, the chain of command began with Qiang Sun, an individual based in China believed to be working for the government. Sun allegedly directed Frank Liu (no relation to Arthur), a prominent figure in the New York Chinese diaspora and head of the World Harmony Foundation, who in turn hired Ziburis to conduct physical surveillance.

Ziburis’s tactics were both deceptive and aggressive. During his surveillance in November 2021, he called Arthur Liu, posing as a representative of the U.S. Olympic Committee. He claimed he needed copies of the Lius’ passports for "travel preparedness" ahead of the Beijing Olympics. Arthur, suspicious of the unusual request, refused. Unbeknownst to Ziburis, he was also being monitored. A private investigator who had previously worked for Frank Liu grew concerned about the legality of the assignments and alerted the FBI. Federal agents watched as Ziburis trailed Arthur to his law office and his home, eventually intervening to warn the Lius of the immediate threat. The pressure was so intense that Arthur and Alysa were forced to board a flight out of California to escape the immediate harassment.

A Chronology of Coordinated Harassment

The plot against the Lius was not an isolated incident but the culmination of a year-long campaign targeting various individuals deemed "dissidents" by the Chinese Communist Party (CCP).

• March 2021: Matthew Ziburis traveled to Southern California, posing as a wealthy art patron interested in purchasing works from Chen Weiming, a sculptor known for his critiques of the CCP. Ziburis surreptitiously installed a GPS tracker on Chen’s vehicle, transmitting his movements back to handlers in Hong Kong.
• July 2021: One of Chen’s most prominent works, the "CCP Virus" sculpture—a 27-foot-tall piece depicting President Xi Jinping as a coronavirus spike protein—was destroyed in a suspicious fire at Liberty Sculpture Park in Yermo, California. While Ziburis and Frank Liu were not charged with the arson, communications recovered by the FBI showed them discussing the destruction of the artwork.
• July 2021: While the surveillance of Chen was ongoing, Frank Liu and Ziburis reportedly discussed methods to spy on a dissident residing in Indiana.
• November 2021: The operation shifted focus to Arthur and Alysa Liu in Northern California, involving direct stalking and fraudulent attempts to obtain sensitive travel documents.
• March 2022: Following a comprehensive investigation, the Department of Justice (DOJ) arrested Frank Liu and Matthew Ziburis. They were charged with stalking and acting as unregistered agents of a foreign government.
• December 2022: Matthew Ziburis pleaded guilty to conspiracy to act as an illegal agent of the People’s Republic of China (PRC) and conspiracy to engage in interstate stalking. He admitted to receiving over $100,000 for his services.

The Role of the United Front and NGO Fronts

A central figure in this network, Frank Liu (born Liu Fan), migrated to the U.S. in 1986 and built a reputation as a bridge-builder between American politicians and Chinese interests. In 2005, he established the World Harmony Foundation. While ostensibly a non-governmental organization (NGO) dedicated to global peace, experts suggest the foundation served as a "United Front" organization. The United Front Work Department is an agency of the CCP tasked with co-opting overseas Chinese communities and influencing foreign elites to align with Beijing’s policies.

Frank Liu’s primary tool for influence was the "Harmony Bell," a large golden prop he brought to high-profile venues, including the United Nations and the U.S. Capitol. By photographing world leaders and diplomats ringing the bell, Liu created a veneer of legitimacy and access. Over the years, he was seen with figures ranging from former UN Secretary-General Kofi Annan to former U.S. Representative Lester Wolff and current New York City Mayor Eric Adams. These connections were allegedly leveraged to provide cover for his activities on behalf of Chinese intelligence, illustrating how cultural and philanthropic organizations can be weaponized for geopolitical ends.

Internal Breaches and Government Compromise

The sophistication of the operation reached into the U.S. government itself. In a startling development, Craig Miller, a long-time deportation officer with the Department of Homeland Security (DHS) based in Minneapolis, was implicated in the scheme. Miller pleaded guilty in late 2022 to obstruction of justice for his role in the case. Federal prosecutors alleged that Miller used restricted government databases to access private information about Arthur and Alysa Liu, which was then funneled to the operatives stalking them.

The involvement of a sitting DHS officer highlights a critical vulnerability in U.S. national security: the recruitment of "insider threats" by foreign intelligence services. By gaining access to federal databases, the Chinese government was able to bypass traditional investigative hurdles, obtaining addresses, travel records, and social security numbers of dissidents. This breach transformed a harassment campaign into a high-stakes intelligence operation, prompting a wider review of how federal agencies protect sensitive data from foreign influence.

Analysis of Implications and Broader Impact

The case of the Liu family serves as a landmark in the U.S. government’s fight against transnational repression. For decades, many incidents of harassment within immigrant communities went unreported or were treated as local criminal matters. However, the DOJ’s "Operation Fox Hunt" and subsequent task forces have begun to treat these actions as direct assaults on American sovereignty.

Human rights advocates argue that Beijing’s willingness to target a high-profile Olympic athlete like Alysa Liu demonstrates a "no-limits" approach to silencing dissent. Even as Alysa represented the United States on the global stage, her father’s past political activism made her a target for leverage. This creates a "chilling effect" within the Chinese diaspora, where individuals may fear that their professional success or the safety of their families depends on their silence regarding the CCP’s human rights record.

Arthur Liu remains vocal about the significance of the plot. He views the intensity of the surveillance as a sign of the CCP’s perceived fragility, noting that the regime feels threatened by even a single dissenting voice from across the Pacific. "Any dissenting voice might topple its rule," Arthur told investigators, "so they have to suppress it."

Conclusion and Current Status

While Matthew Ziburis and Craig Miller have pleaded guilty, Frank Liu has maintained his innocence, with his trial expected to proceed in New York following pretrial briefings this summer. Qiang Sun, the alleged handler in China, remains at large and is believed to be under the protection of the PRC.

Despite the trauma of the 2021-2022 campaign, Alysa Liu’s story has taken a triumphant turn. After a brief retirement following the Beijing Games—where she competed under the watchful eye of both her father and her stalkers—she returned to the ice. In early 2024, she secured an Olympic gold medal, becoming the first American woman to do so in over two decades. Her success, achieved on her own terms and in the wake of federal protection, stands as a resilient rebuttal to the efforts to intimidate her family. However, the legal proceedings and the involvement of U.S. federal employees serve as a stark reminder that the battle against foreign interference continues to evolve, moving from the shadows of espionage into the residential streets of American suburbs.
