China responded on Tuesday to countries and international bodies accusing China of "malicious cyber activities," including March's global Microsoft cyberattack, calling them "groundless."

The White House said on Monday that China "has fostered an intelligence enterprise that includes contract hackers who also conduct unsanctioned cyber operations worldwide, including for their own personal profit."

The United States' condemnation was joined by the United Kingdom, Japan, Australia, New Zealand and Canada as well as the European Union and NATO.

"The allegations in the statements by the EU and NATO are not based on facts and evidence, but speculation and groundless accusations. We express our strong disapproval of and firm opposition to such statements," the Chinese Mission to the EU said in a statement.

According to the embassy in Canberra, Australia is "following the steps and parroting the rhetoric of the US," and it considers the country "an accomplice for the US' eavesdropping activities under the framework of Five Eyes alliance."

"What the Australian government has done is extremely hypocritical, like a thief crying 'stop the thief,'" stated the text.
