China's Vanishing Executives: How Liuzhi Detention Is Reshaping Corporate Risk

A missing chairman brings detention risk into focus

On September 22, Yu Faxin, chairman of Great Microwave Technology, stopped appearing at work. The Shanghai listed company, which makes advanced semiconductor parts for military uses, later disclosed that China's top anticorruption watchdog had taken him away. He had entered liuzhi, a custody system that operates outside normal courts.

Yu's disappearance brought a wider concern into a business that combines sensitive technology with military supply chains. Across technology, finance, property and education, executives have become unreachable for days or months. Some later emerge in official custody or under investigation. Others return without a clear public explanation of their absence.

China has seen prominent businesspeople disappear before. A decade ago, such cases mainly involved Communist Party officials and leaders of state businesses. The reach has since expanded to private company founders, financial dealmakers and scientists, leaving companies to manage sudden gaps at the top.

Corporate announcements often begin with a simple statement: the company cannot contact its chairman or chief executive. Share prices fall, employees scramble for direction, and investors try to assess whether the absence concerns fraud, corruption or broader political discipline. Those uncertainties become part of the price investors are willing to pay for a business.

Authorities describe the investigations as efforts to clean up corruption and financial wrongdoing. Critics see them as a consolidation of party control over an economy that once gave private tycoons considerable freedom. China's leadership wants growth and innovation while also demanding obedience and order. For businesses, those priorities meet in investigations that can reach suppliers, clients and private financial networks, with people held for months without formal charges.

What liuzhi means for someone taken into custody

Liuzhi, which literally means retention in custody, was created in 2018 under the National Supervision Law. It gives the National Supervision Commission and its local branches powers to detain suspects in corruption cases and cases involving wrongdoing connected to official duties.

The system covers a broad range of people: party members, civil servants, employees of state enterprises, managers in public institutions and people working in private companies who are deemed connected to an investigation. An executive's position outside government therefore offers little certainty if investigators consider that person relevant to a case.

A court order is not required. Detainees are denied access to lawyers during the initial phase, and their families are not told where they are being held. The statutory detention limit was extended to as long as eight months. If investigators add new suspicions, the clock can restart.

Human rights groups describe conditions that include monitoring around the clock, constant lighting and intensive interrogation. Public information is often much narrower: an official notice may say only that a person is under investigation, leaving relatives, colleagues and investors without a detailed explanation.

Publicly reported totals, covering officials and businesspeople, rose sharply in 2024 to the order of tens of thousands of cases. The number affecting private firms is likely higher than corporate disclosures suggest because most companies are unlisted and have no obligation to announce that a leader has disappeared.

How a business connection can become an investigation

A state lender, a procurement bureau or a trust investment product can provide the starting point for a much wider inquiry. Investigators may follow transactions to suppliers, borrowers and executives who approved deals years earlier. The business relationship itself becomes a route into the investigation.

Private executives can consequently be drawn into a related case even without a personal corruption accusation. A manager who dealt with an institution under scrutiny may vanish from public view for months while investigators examine the surrounding network.

Local officials also face pressure in a weaker economy to recover money and demonstrate results. That pressure can lead to aggressive measures, including frozen assets, extended custody and interviews with large numbers of connected managers. For a company, the disruption may therefore reach beyond the absent executive to its funds and other employees.

Investors have to weigh that exposure alongside ordinary business risks. A company's financial condition, its dealings with public institutions and the past decisions of its senior managers can all become relevant when an investigation spreads through a commercial network.

Different sectors face different triggers

Finance chiefs and dealmakers have been especially exposed as capital markets and property finance come under strain. Property business heirs and insurance executives have faced investigations after a long expansion of credit turned sour.

Technology founders have encountered political limits involving data, competition and the power of large platforms. Executives in military supply chains, including Yu Faxin, operate where sensitive technology meets strict political oversight. The circumstances vary by industry, but the immediate corporate experience is often similar: an executive falls silent, a brief filing follows, and the official process remains opaque.

Those brief announcements give employees and shareholders little guidance about how long the disruption may last. Some business leaders return quickly; others eventually receive lengthy prison sentences. The absence of clear boundaries can change executive behavior far beyond the wording of the law.

Executives at streaming and gaming platforms have also faced arrests and questioning, reflecting continuing scrutiny of the internet industry. Taken together, the cases stretch across businesses with very different products, customers and sources of financing.

A decade of prominent disappearances

Guo Guangchang of Fosun and Yim Fung of Guotai Junan Securities were among the prominent figures who became unreachable in 2015 and later returned. Their experiences began a sequence of widely watched cases whose outcomes ranged from a resumption of work to long imprisonment.

The chronology shows both the breadth of the businesses involved and the different paths that followed an executive's disappearance:

• 2015: Fosun founder Guo Guangchang was unreachable for several days before returning after assisting an investigation. Guotai Junan Securities chairman Yim Fung also went missing and later resumed his duties after helping authorities.
• 2017: Financier Xiao Jianhua was taken from a hotel in Hong Kong. He was later jailed on charges including bribery and the illegal use of funds.
• 2018: Wu Xiaohui, who built Anbang Insurance, received a long prison sentence for fraud and embezzlement after being detained. CEFC China Energy head Ye Jianming vanished from public view that year and has been named in multiple graft cases.
• Late 2020: Jack Ma disappeared from public view after criticizing financial regulators. Ant Group's initial public offering was halted, and a lengthy regulatory restructuring began.
• 2020: Real estate tycoon Ren Zhiqiang, who criticized China's top leadership, was sentenced to 18 years in prison for graft.
• 2023: Technology dealmaker Bao Fan disappeared before his firm said he was cooperating with an investigation. Seazen senior executive Qu Dejun became unreachable before resigning, with little public detail.
• 2025: Ma appeared at a gathering with top leaders and business heads. On September 22, Yu Faxin stopped appearing at work, and Great Microwave Technology later disclosed his detention.

Qu's resignation and the limited information surrounding it illustrate the difficulty facing shareholders when an executive's absence is announced without a fuller explanation. Bao's case, meanwhile, showed how quickly that uncertainty could affect a financial business built around prominent personal relationships.

Zhongzhi's financial crisis spreads through its network

Zhongzhi Enterprise Group became a flashpoint in 2023 as China's shadow banking businesses came under pressure. Shadow banking is a broad term for financing outside the formal banking balance sheet. Zhongzhi was a large private financial group controlling several asset managers and a trust company.

The group warned investors that its liquidity had collapsed. In simple terms, it lacked the cash needed to meet demands for payment. A related trust missed payments to individual and corporate investors, prompting protests and fears that trouble would spread as property developers defaulted.

Trusts had directed money into property and other projects promising high returns during the boom. When cash flow dried up, investors demanded repayment. The pressure moved from unpaid investments to criminal investigations and the leadership of businesses connected to the group.

Several executives at linked companies became unreachable during that period. An education business said it could not contact its chairwoman, a veteran of Zhongzhi. A livestock and dairy company in Xinjiang said it had lost contact with its chairman, who also held a senior role at the group.

The corporate filings used identical language and offered no explanation beyond the inability to communicate with the executives. The announcements came days after Beijing police disclosed a criminal investigation into Zhongzhi's wealth management unit, the part of the business dealing with investment products for clients.

What companies and police said about Zhongzhi

Dalian My Gym Education Technology identified its chairwoman, Ma Hongying, as the executive it could not reach. The company's statement described its immediate situation in these terms:

Dalian My Gym Education Technology said it is unable to get in touch with its chairwoman Ma Hongying.

Beijing police announced action against suspects as the investigation escalated. Their statement described the measures taken and identified one suspect by surname:

Beijing police said they had enforced mandatory criminal measures against a number of suspects, including one surnamed Xie.

The Zhongzhi crisis joined three pressures that businesses and investors were already facing: failed payments, demands to recover money and investigations extending through senior management. Police action and the sudden absence of executives signaled a willingness to pursue alleged wrongdoing and broader accountability across the group's network.

The case also brought the stress in finance into sectors that looked quite different from an investment group. An education company and a livestock and dairy business became part of the same public uncertainty because their leaders had connections to Zhongzhi.

Technology founders lower their public profiles

Jack Ma's retreat from public view followed his criticism of financial regulators in late 2020. The halt to Ant Group's initial public offering interrupted a major planned stock market debut, while the regulatory restructuring that followed changed the course of the business.

Ma later resurfaced outside mainland China and took up teaching and agricultural projects. By 2025, he had appeared at a gathering with top leaders and business heads. His trajectory offered other founders a guide to adjusting to the changed environment: step back, comply with rule changes and maintain a lower profile.

Bao Fan's disappearance in 2023 carried a different kind of shock through the technology sector. He had helped arrange many of its mergers and stock market listings. Investors in his firm reacted with alarm, and its share price fell sharply before the company said he was cooperating with an investigation.

Private equity and venture investment partners now spend more time examining compliance, requirements to keep data within the country and political considerations alongside a company's finances. Investment decisions increasingly involve assessing how a business fits regulatory and political expectations, as well as whether it can grow.

The cost of capital rose in certain sectors as investors demanded greater compensation for risk. That means some companies faced a higher price for attracting money, adding a financial consequence to the uncertainty surrounding prominent founders and dealmakers.

Support for enterprise comes with demands for alignment

China's leadership has sought to signal support for private enterprise while requiring businesses to align with policy goals. Xi Jinping, general secretary of the Communist Party, addressed the conduct expected of private entrepreneurs in a speech to delegates at the National People's Congress.

The pressure on executives sits within that wider balance. Private businesses are needed for growth and innovation, while their founders and managers face demands for political discipline and compliance. Yu's case places that tension in a company producing advanced components for military use; Zhongzhi's troubles place it in financial networks struggling to repay investors.

Companies must respond to the practical consequences of an absence before they have a detailed account of the investigation. Employees need direction, investors reassess the value of their holdings, and colleagues may face questioning or disruptions involving company assets.

Executives across these sectors face different reasons for scrutiny, but the uncertainty has become a shared corporate concern. A sudden disappearance can affect a company's leadership, its financing and the willingness of business partners to proceed with deals, even while official information remains limited.
