RightsCon, the world’s largest digital rights conference, was canceled this year due to pressure from the Chinese government, according to the nonprofit organization that organizes the annual event.

In a statement, Access Now says it was “told that diplomats from the People’s Republic of China (PRC) were putting pressure on the Government of Zambia because Taiwanese civil society participants were planning to join us in person.”

The Chinese Embassy in Washington, DC, and the United States Taipei Economic and Cultural Representative Office did not immediately respond to requests for comment. When WIRED called the Zambian embassy in Washington, a member of the staff answered the phone and transferred the call to another staff member who then picked up for several seconds before hanging up. A follow-up call went unanswered.

Access Now says it was told “informally from multiple sources” that “in order for RightsCon to continue, we would have to moderate specific topics and exclude communities at risk, including our Taiwanese participants, from in-person and online participation.”

RightsCon 2026 was set to feature several panels on China’s international influence, including about how Beijing exports digital authoritarianism and spreads disinformation in regions like Africa, as well as discussions on Chinese cyberattacks and the global spread of its censorship and surveillance technologies.

Arzu Geybulla, the co-executive director of Access Now, tells WIRED that “multiple pieces of information we received indicated that foreign interference by the People’s Republic of China played a role in the abrupt disruption of RightsCon 2026.”

A week before the conference was scheduled to take place in Lusaka, Zambia, the Zambian government abruptly announced that it would be postponed to an unspecified date. In a statement on April 28, the country’s minister of technology and science, Felix Mutati, said that certain “speakers and participants remain subject to pending administrative and security clearances.” The following day, Thabo Kawana, Zambia’s minister for information and media added that the “postponement was necessitated by the need for comprehensive disclosure of critical information relating to key thematic issues proposed for discussion during the Summit.”

On April 27, two days before the Zambian government’s announcement, Access Now “became aware that the in-person participation of people from Taiwan had caught the attention of the Government of the People’s Republic of China. In turn, Chinese authorities were, apparently, trying to influence the Zambian government’s approach to Taiwanese participants’ movement across the border,” says Geybulla. “Soon after, the Zambian government publicly referred to ‘diplomatic protocols’ and ‘pending administrative and security clearances’ of participants as reasons for their disrupting RightsCon.”

Open Culture Foundation, a Taiwanese nonprofit organization that was scheduled to attend RightsCon this year, says that it was warned by Access Now that Taiwanese citizens may have problems entering Zambia due to possible concerns from the Chinese Embassy. They were told to pause their travel plans while the host coordinated with Zambian officials.

Nikki Gladstone, RightsCon director at Access Now, confirmed to WIRED that the organization had been in contact with Taiwanese participants about potential issues traveling to Zambia. “Given the potential access issues this would present to that community, many of whom were set to begin traveling imminently, we felt a duty to inform our registered Taiwanese participants of this development while we sought more details and information,” says Gladstone. “We said we would be hesitant to recommend travel until there was more clarity.”

An employee of another human rights organization, who asked not to be named for security reasons, tells WIRED that after RightsCon was officially postponed, they were told by one of their grant funders that the Chinese government had been pressuring the Zambian government for days over the presence of a Taiwanese delegation at the conference.
