BEIJING (AP) — China says Canada’s accusation that it was behind the hacking of a Canadian technology development organization is groundless and irresponsible.

Foreign Ministry spokesman Qin Gang said in a statement issued Thursday that Canada should withdraw the accusation.

Canada’s Treasury Board said on Tuesday that a “highly sophisticated Chinese state-sponsored actor” hacked into the National Research Council, which partners with private industry to bring new technologies to market.

The government said one of Canada’s spy agencies detected and confirmed the cyberattack. The council’s computers were isolated as a precaution. The government wouldn’t release more information for security reasons.

In May, the U.S. accused China of vast business spying and charged five military officials with hacking into U.S. companies to steal vital trade secrets.
