British handover of the territory

China warns the United Kingdom that "no country has the right to intervene on the issue of mass protests in Hong Kong", as it considers the problems of this self-governed city an "internal problem". For China, the agreement by which the United Kingdom returned Hong Kong is nothing more than "a historical document of no practical importance" and "that European country no longer has any responsibility over Hong Kong". The British chancellery, for its part, dismissed the Chinese opinion, and has said that "it is the right and obligation of the United Kingdom to work to enforce the agreement", which, in theory, guarantees a high degree of autonomy for Hong Kong for 50 years until 2047 without Chinese interference.
