The Czech Republic said on Wednesday China was responsible for a "malicious cyber campaign" targeting a network used for unclassified communication at the Foreign Affairs ministry, and summoned the Chinese ambassador to condemn the incident.

The attacks have been ongoing since 2022 and were perpetrated by the cyber espionage actor APT31, which the Czech Republic, an EU state and NATO member, said was publicly associated with the Chinese Ministry of State Security.

The Chinese embassy in Prague did not immediately respond to a request for comment. NATO and the European Union said they stood in solidarity with the Czech Republic.
Foreign Minister Jan Lipavsky said on X that after the attack was detected, the ministry implemented a new communications system with enhanced security.
