Hackers linked to the Chinese government launched a state-sponsored operation that targeted New Zealand’s Parliament in 2021, the country’s security minister said Tuesday.

New Zealand’s allegation comes a day after American and British authorities announced a set of criminal charges and sanctions against seven hackers, all believed to be living in China, who targeted U.S. officials, journalists, corporations and pro-democracy activists, as well as the U.K.’s election watchdog.

“The use of cyber-enabled espionage operations to interfere with democratic institutions and processes anywhere is unacceptable,” Judith Collins, the defense minister responsible for the Government Communications Security Bureau, said in a statement.

Collins said the agency had also established links between a state-sponsored entity linked to China and malicious cyber activity targeting parliamentary entities in New Zealand.
