In Hong Kong, the aftermath of the 2014 Hong Kong protests and Legislative Council oath-taking controversy saw the imprisonment of Hong Kong democracy activists and Benedict Rogers, a British human rights activist, intended to visit them privately. On 11 October 2017, Rogers was barred entry to Hong Kong. He arrived at Hong Kong International Airport on a flight from Bangkok but was escorted away by immigration officials and placed on a flight back to Thailand. He had previously been warned by a contact in the Chinese embassy in London that he might be refused entry to Hong Kong. Rogers, who lived in Hong Kong between 1997 and 2002, has criticised what Rogers says is Mainland China's increasing threat to democracy in Hong Kong and has campaigned against the imprisonment of pro-democracy activists Joshua Wong, Nathan Law and Alex Chow. British Foreign Secretary Boris Johnson demanded an explanation from the Hong Kong authorities and the Central Chinese government. Hua Chunying, a spokeswoman for the Chinese Foreign Ministry, later responded that the move was within China's sovereignty and said: "Whether this person's trip to Hong Kong involved an intention to intervene in Hong Kong's internal affairs and judicial independence – he knows very well himself."
