Chinese intelligence activity abroad
Russian investigators accuse Valery Mitko, President of Arctic Academy of Sciences in St. Petersburg and one of the country's leading Arctic researchers, "of treason" after alleging that he gave a document containing state secrets to Chinese intelligence in early 2018 at China's Dalian Maritime University, where he was a visiting professor. Mitko and his lawyer Ivan Pavlov deny any wrongdoing and say that all the materials were openly available.
