During the year 2020, our team at the European Values Center for Security Policy has, thanks to the support of the Konrad Adenauer Foundation, implemented a project to evaluate these two hostile actors’ influence activities in the Czech Republic since 2014. Around 2014, the aggressiveness of these regimes against European democracies and the Czech Republic underwent a fundamental shift. Consequently, based on a series of consultations with Czech governmental and non-governmental specialists, we have prepared a simplified summary – a chronology of the most serious cases of Russian and Chinese influence in the Czech Republic.
