Chinese Ambassador to Britain Liu Xiaoming speaks during a press conference in London, Britain, Aug. 15, 2019. Hong Kong is part of China and foreign forces must stop interfering in Hong Kong's affairs, Liu said on Thursday. Evidence shows that the situation in Hong Kong would not have deteriorated so much had it not been for the interference and incitement of foreign forces, Liu told the press conference at the Chinese Embassy in Britain.
