Hong Kong`s governance has helped it become the main gateway for foreign investment in China, in part because many global companies do not trust regulators and the continental legal system. The United States also considers Hong Kong to be the rest of China for trade purposes, which means, among other things, that it is exempt from President Donald Trump`s tariffs on Chinese products. U.S. lawmakers from both major parties have said they will reconsider Hong Kong`s special status if they believe China is undermining the city`s autonomy. There is no mention in the U.S. law on what happens after 2047. The proposals in Article 23 of the Basic Law of 2003 (which were withdrawn due to massive opposition) were omitted. In the ensuing discussions, in which the Governor of Hong Kong participated in each round of formal talks as a member of the British delegation, it became clear that the continuation of the British government after 1997 would not be acceptable to China.  The Chinese government has always considered that the whole of Hong Kong should be a Chinese territory, since it is acquired because of the inequality of historical contracts.  As a result, both parties discussed possible measures in addition to the british government`s pursuit and considered the concept of Hong Kong as a special administrative region of the PRC. In April 1984, the two sides concluded the first discussion on these issues, arranging for Hong Kong to maintain a „high“ degree of autonomy under Chinese sovereignty, while maintaining Hong Kong`s well-maintained lifestyle.
 Until 18 September 1984, both parties had approved the English and Chinese texts of the documents and the exchange of memorandums. The previous year, the Provisional Legislative Council passed laws restricting the right of residence, which led to proceeding against the government, which ended in 1999 with a loss for the government before the Court of Final Appeal. The government then took its case to the National People`s Congress. The law expressed disapproval of the law, which Martin Lee described as „giving“ to Hong Kong`s autonomy through a silent march. Polls showed that the events had weighed on public confidence in the government, although most were supportive of the government`s attitude towards that of the court.  Macau did not react in the same way, unlike the numerous demonstrations and riots that broke out in Hong Kong.  According to Jason Chao, a former president of the Pro-Democracy New Macao Association, Macau is in a different situation than Hong Kong because Macau does not want freedom and autonomy.  Instead, the majority of Macau`s population is pro-Chinese.   One reason is that about half of the 600,000 people living in Macau are Chinese immigrants.  In December 2019, Li Zhanshu, chairman of the Standing Committee of the National People`s Congress, said there was a „strong sense of international identity“ in Macau.
 In the first speech of the Secretary General of the Communist Party of China, Xi Jinping, in Macau in December 2019, on the occasion of the twentieth anniversary of the handover of the Portuguese to the Chinese, he described Macau as a „magnificent chapter in the short history of a country, two experiences of systems“.  The current Chief Executive, Ho Iat Seng, said that „Macao will be an example of China`s reunification,“ and Xi agreed with the „Macau model“ because Macau has properly followed the „one country, two systems“ agreement.   As a reward for Macau`s peaceful behaviour and lack of anti-government protests, Xi Jinping Macau has given more Chinese land to Hengqin Island.  The aim is to enable Macau to develop its education and health system and to integrate Macao more physically with China.   Hong Kong could formally join the People`s Republic, with an improved version of autonomy enjoyed by some of China`s most dynamic regions, such as the Special Economic Zone that includes Shenzhen.
