Faced with the increasing openness of the PRC government and continental economic reforms, Margaret Thatcher, then British Prime Minister, strove to obtain the PRC`s agreement on the continuation of the British presence in the region.  Britain quickly resorted to this unofficial part of the agreement and attacked Kowloon Walled City in 1899 just to leave it. They did nothing with or with the outpost, thus raising the question of the ownership of Kowloon Walled City directly in the air. The outpost consisted of a yamen and buildings that from the 1890s to the 1940s developed into deep, dense neighborhoods. The agreement signed in 1984 was to last until 2047. But before Hong Kong was returned, Britain and China agreed to set up “one country, two systems.” Hong Kong`s autonomy was guaranteed by the “One Country, Two Systems” agreement, enshrined in the Sino-British joint declaration signed by then Chinese Premier Zhao Ziyang and British Prime Minister Margaret Thatcher. 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 pose deng Xiaoping on the issue of Hong Kong sovereignty.  In the absence of clarification and definition of the official position of the Government of the PRC, the intermediation of real estate leases and credit agreements in Hong Kong would be difficult over the next 18 years.  The list included Hong Kong government officials, members of the Legislative and Executive Council, presidents of the Hongkong and Shanghai Banking Corporation and Standard Chartered Bank, prominent businessmen like Li Ka-shing, Pao Yue-kong and Fok Ying-tung, as well as Martin Lee Chu-ming and Szeto Wah.
