For a week in January 2018, Marriott International was kicked out of China’s cyberspace.

Following a customer questionnaire released by the hotel company that listed Tibet, Hong Kong, Macau and Taiwan as separate countries, the Shanghai Cyberspace Administration shut down Marriott’s Chinese website and mobile phone application. China regards all four regions as unequivocally within its sovereignty. Marriott quickly apologized for incident, but the Shanghai Cyberspace Administration opened an investigation into whether Marriott’s actions violated the country’s recently passed cybersecurity law.
