The Joint Declaration of the Salts and the British consists of eight paragraphs, three annexes on basic policy for Hong Kong, the Sino-British Joint Liaison Group and the Land Leases, as well as the two memorandums of both parties. Each party has the same status and « the whole forms a formal international agreement, legally binding in all its elements. Such an international agreement is the highest form of engagement between two sovereign states.  As part of these declarations, the Hong Kong Special Administrative Region is under the control of the central government of the People`s Republic of China and enjoys a high degree of autonomy, with the exception of foreign affairs and defence. It is authorized to have executive, legislative and independent powers, including final decision-making power. The Basic Law specifies that in addition to Chinese, English can also be used in government bodies and that in addition to the national flag and the national emblem of the PRC, the HKSAR can use its own regional flag and logo. It aims to maintain the capitalist economic and commercial systems previously practiced in Hong Kong. The third paragraph lists the basic policies of the PRC with regard to Hong Kong: the joint statement of the British in Innos does not have a mechanism approved by both parties to ensure compliance. Although registered with the United Nations, the Agreement did not contain any oversight mechanisms by the United Nations. Therefore, only the signatories of the declaration have the right to address any violations of the conditions. The list includes Hong Kong government officials, members of the legislative and executive councils, presidents of Hong Kong and Shanghai Banking Corporation 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. The communist press published reports that the project was a bad plan to bleed at ease in Hong Kong before the handover and let the territory take on serious debt.  After three years of negotiations, Britain and the PRC finally agreed on the construction of the new airport and signed a Memorandum of Understanding.  To remove the hills and reclaim the land, it took only a few years to build the new airport.
Hong Kong`s autonomy was guaranteed by the « one country, two systems » agreement, enshrined in the 1984 Sino-British Joint Declaration signed by then-Chinese Prime Minister Zhao Ziyang and British Prime Minister Margaret Thatcher. 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 relationship between Hong Kong and mainland China is much more complex than most people recognize. It is about politics, economics, trade, laws and, above all, people. The So-called « Hong Kongers, » who have sanitized for years under the influence and ways of the former British leader, are cautious with China`s intentions and are outraged at the continent`s interference in its political affairs. But the UK says the deal – known as a joint declaration – is under threat because the region has passed a new law that gives China new extended controls over Hong Kong residents. Britain quickly re-established 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.
