The British Government takes extremely seriously our longstanding duty to uphold the implementation of the Sino-British Joint Declaration. It is a legally binding treaty, registered with the UN, and remains in force until 2047. We will continue to monitor closely events in Hong Kong, speaking publicly on issues of concern. We regularly raise our concerns directly with the Chinese and Hong Kong Special Administrative Region (SAR) Governments. The Foreign Secretary raised Hong Kong, and the importance of the Joint Declaration, with Chinese State Councillor Wang Yi on 31 July. He also spoke to Hong Kong Chief Executive Carrie Lam on 9 August, when he noted our support for Hong Kong's high degree of autonomy, and our commitment to 'One Country, Two Systems'.
