The signing of the joint declaration caused some controversy in the United Kingdom, as British Prime Minister Margaret Thatcher accepted the Chinese Communist government, represented by Deng Xiaoping.  In the White Paper containing the Joint Statement, Her Majesty`s Government stated that “the alternative to the adoption of this agreement is not to reach an agreement”, a statement that refuted criticism that the Declaration had made too many concessions to China and highlighted China`s considerable influence during the negotiations.  The list included representatives of Hong Kong, members of the legislative and executive councils, presidents of the Bank of Hong Kong and Shanghai and Standard Chartered Bank, prominent businessmen such as Li Ka-shing, Pao Yue-kong and Fok Ying-tung, Martin Lee Chu-ming and Szeto Wah. Some political analysts felt that an agreement was urgently needed, as there were fears that Hong Kong`s economy would collapse untreated in the 1980s. Concerns about land ownership in the new leased territories also contributed to the problem. Although discussions on Hong Kong`s future began in the late 1970s, the final date of the joint declaration was influenced by factual and economic factors rather than geopolitical imperatives.  One of the most important achievements has been to ensure the continuity of the independent judicial system in Hong Kong, including agreements in the areas of commercial navigation, civil aviation, nuclear materials, whale fishing, the Submarine Telegraph, space and many others. It also agreed to a network of bilateral agreements between Hong Kong and other countries. Under these agreements, agreements were reached for the continued implementation of some 200 international conventions to HKSAR after 30 June 1997. Hong Kong is expected to continue to participate in various international organizations after the handover. In March 1979, Hong Kong Governor Murray MacLehose made his first official visit to the People`s Republic of China (PRC) and took the initiative to raise the issue of Hong Kong sovereignty with Deng Xiaoping.  Without clarification and definition of the official position of the Government of the People`s Republic of China, it would be difficult to arrange real estate and loan leases in Hong Kong in the next 18 years.  Britain quickly returned to this unofficial part of the agreement and attacked Kowloon Walled City in 1899 to find it abandoned.
They didn`t do anything with it, or the outpost, and the question of ownership of Kowloon Walled City was directly in the air. The outpost consisted of a yamen, as well as buildings that grew up in sparsely populated neighborhoods from the 1890s to the 1940s.
