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. During the 2014 Umbrella Revolution, a campaign against perceived violations of mainland China in HKSAR, Chinese officials concluded for the first time that China considered the joint declaration “invalid,” according to a British MP.  This conclusion was found to be “manifestly erroneous” by a senior Hong Kong lawyer and rejected by the British Foreign Minister, who stated that the document was a legally binding agreement that had to be respected.   Rita Fan, then Hong Kong`s only representative on the Standing Committee of the National People`s Congress in Beijing, stated that responsibility for the UK`s oversight had expired and that the joint declaration did not provide for universal suffrage.  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. 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, underwater 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.
The agreement signed in 1984 was to last until 2047. 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. The outpost consisted of a yamen, as well as buildings that grew up in sparsely populated neighborhoods from the 1890s to the 1940s. The joint overall declaration between Salina and Great Britain 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. This group was a connection organ, not a power organ, where each party could send up to 20 support coworkers.
It is expected to meet at least once a year at each of the three sites (Beijing, London and Hong Kong). It was established in Hong Kong on July 1, 1988. It should also help HKSAR maintain and develop economic and cultural relations and conclude agreements on these issues with the relevant states, regions and international organisations, and could therefore create specific sub-groups. Between 1985 and 2000, the Joint Liaison Group held 47 plenary sessions, 18 in Hong Kong, 15 in London and 14 in Beijing. 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. 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.
