Harvard University’s links to China, long an asset to the school, have become a liability as the Trump administration levels accusations that its campus is plagued by Beijing-backed influence operations.

On Thursday the administration moved to revoke Harvard’s ability to enroll foreign students, saying it fostered antisemitism and coordinated with the Chinese Communist Party. Among them are Chinese nationals who made up about a fifth of Harvard’s foreign student intake in 2024, the university said.

A US judge on Friday temporarily blocked the administration’s order after the Cambridge, Massachusetts, university sued.

The concerns about Chinese government influence at Harvard are not new. Some US lawmakers, many of them Republicans, have expressed worries that China is manipulating Harvard to gain access to US advanced technology, to circumvent US security laws and to stifle criticism of it in the United States.

“For too long, Harvard has let the Chinese Communist Party exploit it,” a White House official told Reuters on Friday, adding the school had “turned a blind eye to vigilante CCP-directed harassment on-campus.”

Harvard did not respond immediately to requests for comment.

The school has said the revocation was a punishment for Harvard’s “perceived viewpoint,” which it called a violation of the right to free speech as guaranteed by the US Constitution’s First Amendment.

Harvard’s links to China, which include research partnerships and China-focused academic centers, are longstanding. The ties have yielded major financial gifts, influence in international affairs and global prestige for the school.

Former Harvard President Larry Summers, who has at times been critical of the university, called the Trump administration’s move to block foreign students the most serious attack on the university to date.

“It’s hard to imagine a greater strategic gift to China than for the United States to sacrifice its role as a beacon to the world,” he said in an interview with Politico.

HEALTH TRAINING

In a statement, the Chinese embassy in Washington said: “Educational exchanges and cooperation between China and the United States are mutually beneficial and should not be stigmatized.”

The presence of Chinese students at Harvard and the school’s links to the country are not evidence of wrongdoing. But the complexity and overlapping nature of the connections have been opaque enough to attract attention and criticism.

The China-related issues cited by the Trump administration echo the work of the Republican-led House of Representatives’ Select Committee on China.

For example, Harvard provided public health-related training to Xinjiang Production and Construction Corps (XPCC) officials after 2020. That year the US imposed sanctions on the Chinese paramilitary organization for its role in alleged human rights abuses against Uyghurs and other Muslim ethnic groups in Xinjiang.

The Department of Homeland Security said those engagements with XPCC continued “as recently as 2024.”

China vehemently denies any accusations of wrongdoing in Xinjiang, but both the Trump and Biden administrations have defined Beijing’s policies in the region as “genocide.”

In another episode that has drawn questions, US business intelligence firm Strategy Risks said that Ronnie Chan, who facilitated a $350 million donation to Harvard in 2014 that led to its school of public health being named for his father, property developer T.H. Chan, is a member of the China-United States Exchange Foundation.

The Hong Kong-based organization, which says its aim is to foster dialogue between the two countries, has been classified as a foreign principal under US law, requiring US lobbyists working for it to disclose that work to the US government.

FORMER PROFESSOR CONVICTED

Former Harvard Professor Charles Lieber was scrutinized by a Trump program started in 2018 called the China Initiative, which was focused on fighting Chinese espionage and intellectual property theft and investigated researchers and universities over whether they disclosed financial ties to Beijing.

He was convicted in 2021 of lying about his ties to China in connection with federally funded research. In April, he became a full-time professor, opens new tab at a Chinese university.

The initiative was halted under the Biden administration after critics said it led to racial profiling and a culture of fear that chilled scientific collaboration.

US lawmakers from both parties have expressed worries about the efforts by Beijing-linked student associations to monitor political activities. In April 2024, a Harvard student activist was physically ejected from an event by a Chinese exchange student - not faculty or security staff - for interrupting a speech by China’s Ambassador Xie Feng.

Pressure has mounted on Harvard in Trump’s second term, with the Education Department in April asking the university to provide records on its foreign funding after it said a review of required reporting on large foreign-source gifts and contracts revealed incomplete and inaccurate disclosures.

The Trump administration’s moves against Harvard have nonetheless alarmed some China experts.

Yaqiu Wang, a US-based human rights researcher who came to the US from China as a student, said the Trump administration’s move to ban foreign students at Harvard was “completely counterproductive.”

“The concerns over the Chinese government’s transnational repression attempts to silence critics are very legitimate, and also espionage concerns are legitimate.” Wang said. “But to try to address that by banning, not only Chinese students, but foreign students, is just beyond comprehension.”
