The Czech Republic has formally accused China of carrying out cyberattacks targeting its Foreign Ministry’s communication infrastructure. Officials claim that the operation, allegedly conducted by the state-sponsored hacking group APT31, began in 2022 and compromised critical government systems. This revelation has further strained Czech-China relations and prompted strong reactions from international allies, including the United States, NATO, and the European Union.
I. The Cyberattack: Details and Accusations
1. Czech Foreign Ministry Points to APT31
According to a statement released by the Czech Foreign Ministry, the cyberattacks began in 2022 and aimed at the country’s critical communications systems. Authorities have linked the campaign to APT31, a hacking group believed to be affiliated with China’s Ministry of State Security. While the extent of the damage and the specific data compromised remain undisclosed, officials emphasized that a new secure communication system has already been implemented in response.

2. Strong Condemnation from Czech Officials
Czech Foreign Minister Jan Lipavský expressed serious concerns over the breach. In response to the incident, the ministry summoned the Chinese ambassador to Prague to issue a formal protest. Lipavský emphasized that such actions have significant implications for diplomatic relations and directly contradict China’s public commitments to cybersecurity norms. The government has condemned the attack, calling it a direct threat to national infrastructure and trust between nations.
II. China’s Denial and International Reactions
1. Beijing Denies Involvement
In response to the accusations, the Chinese Embassy in Prague dismissed the claims as “unfounded.” China reiterated its official stance that it opposes all forms of cyberattacks and does not support or engage in hacking activities. Beijing asserted that the Czech allegations lack credible evidence and are damaging to bilateral ties.
2. U.S. Joins Czech Republic in Condemnation
The U.S. Embassy in Prague issued a strong statement supporting the Czech government’s position. The United States accused APT31 of having a history of targeting political figures, foreign policy professionals, and sectors vital to national security—including defense, IT, and energy. U.S. officials called for an immediate end to such activities and reaffirmed their commitment to countering malicious cyber behavior originating from China.
3. NATO and EU Express Solidarity
The incident has drawn criticism from both NATO and the European Union. NATO warned of a troubling trend in cyberattacks linked to China and stressed that such incidents violate established international cybersecurity norms. EU foreign policy chief Kaja Kallas echoed these sentiments, labeling the attack “unacceptable” and affirming that the European bloc would not tolerate hostile digital actions against its member states.
III. A Pattern of Cyber Intrusions
1. Previous Attacks on Czech Officials
This is not the first time the Czech Republic has been targeted in a sophisticated cyber operation. In 2017, hackers successfully accessed the email account of then-Foreign Minister Lubomír Zaorálek and several ministry staff members. While the attacker’s identity remained undisclosed at the time, the nature of the breach suggested the involvement of a foreign state actor. The 2022 attack, now attributed to China, adds to a growing list of cyber intrusions threatening the country’s political and administrative structures.
2. Persistent Threats from State-Sponsored Hackers
The recent accusations highlight a broader concern about state-sponsored cyber espionage campaigns targeting democratic governments. APT31 has previously been accused of stealing intellectual property and sensitive data from entities across various sectors globally. The Czech case reinforces fears that such activities are part of a larger strategic effort to undermine critical infrastructure, gather intelligence, and sow discord among Western nations.
3. The Role of Critical Infrastructure in National Security
The attack on the Czech Foreign Ministry demonstrates how deeply integrated cybersecurity is with national defense. Targeting communication networks is not only disruptive but can compromise diplomatic strategies, sensitive discussions, and operational readiness. For nations like the Czech Republic, protecting digital infrastructure has become a central component of national security policy.
IV. The Global Response to Cyber Aggression
1. Elevating Cybersecurity in Foreign Policy
The Czech incident underscores a broader trend where cybersecurity is becoming an increasingly vital aspect of international diplomacy. Countries are not only strengthening internal cyber defenses but also forming coalitions to hold aggressors accountable. Summoning ambassadors, issuing public condemnations, and initiating multi-lateral responses are part of the evolving diplomatic toolkit in the digital age.
2. Legal and Diplomatic Challenges Ahead
Attributing cyberattacks to state actors remains technically challenging and politically sensitive. Despite growing evidence and advanced threat analysis, proving a direct link between a cyber operation and a foreign government can be difficult. This complicates efforts to hold perpetrators accountable under international law, leaving victim states to rely on coordinated public responses, economic measures, or cyber countermeasures.
3. The Call for International Cyber Norms
Incidents like the one in the Czech Republic reignite discussions on establishing universal norms and agreements governing cyber conduct. While initiatives exist under organizations such as the United Nations, enforcement remains weak. As cyberattacks become more common and more sophisticated, global cooperation and norm-setting will be essential in deterring future breaches and promoting accountability.
Conclusion
The Czech Republic’s accusation against China for orchestrating a cyberattack on its Foreign Ministry highlights the rising stakes in international cybersecurity. As digital threats grow in complexity and frequency, nations are increasingly forced to respond both technically and diplomatically. While China denies involvement, the backing of allies such as the U.S., NATO, and the EU signals a unified front against cyber aggression. Going forward, the global community must push for greater transparency, stronger defenses, and enforceable norms to safeguard digital sovereignty and international stability.
