China has called the US arrogant and selfish after it charged two Chinese citizens with stealing trade secrets and other sensitive information from American government agencies and corporations.
Foreign ministry spokeswoman Hua Chunying accused the US of undermining other countries' development in order to defend its own hegemony.
Ms Hua spoke at a regular news briefing after she had condemned the US in a written statement earlier in the day for "fabricating facts" on the hacking charges.
The US indicted Zhu Hua and Zhang Shilong for allegedly carrying out an extensive cyber espionage campaign on behalf of Beijing's main intelligence agency.
They are accused of breaching computers linked to companies in at least 11 other countries, including the UK, Japan and India.
