Beijing accused the United States on Thursday of smearing China after Washington alleged Chinese hackers were attempting to steal research on developing a vaccine against the coronavirus.
The claims have added fuel to tensions between the global superpowers, who have traded barbs over the origin of the pandemic that has killed 300,000 people.
US authorities said Wednesday that Chinese hackers were trying to obtain coronavirus data on treatments and vaccines, warning the effort involved Chinese government-affiliated groups and others.
The FBI and the Cybersecurity and Infrastructure Security Agency said China’s efforts posed a “significant threat” to the US response to COVID-19.
“China expresses strong dissatisfaction and firm opposition to such smearing,” foreign ministry spokesman Zhao Lijian told a regular press briefing.
