BEIJING - China is strongly dissatisfied with and firmly opposes Britain's practice of political manipulation under the guise of cybersecurity, and has lodged stern representations in Beijing and London, said the Chinese Foreign Ministry on Wednesday.

Spokesperson for the ministry Guo Jiakun made the remarks at a daily news briefing when commenting on the report that the British government on Tuesday announced sanctions against two Chinese companies, claiming that the relevant companies had launched cyberattacks against Britain and its allies and that their actions were related to the Chinese government.
