An FCDO Spokesperson said:
Today, on instruction from the Foreign Secretary, the Chargé d'Affaires of the Chinese Embassy in London was summoned to the Foreign, Commonwealth & Development Office.
The FCDO set out the Government's unequivocal condemnation of Chinese state-affiliated organisations and individuals undertaking malicious cyber activity against UK democratic institutions and parliamentarians. The UK Government would not tolerate such threatening activity, and would continue to take strong action with partners across the globe to respond.
The summons followed yesterday's announcement in Parliament by the Deputy Prime Minister, that the UK had imposed tough, targeted sanctions on a front company and two individuals involved in China's malicious cyber activity targeting officials, Government entities, and parliamentarians around the world.
