Hong Kong: One Country, Two Systems and Its Real Structural Tensions

Chinese Political History II: Reform, Opening & the Rise of Modern China

Chapter 8 · Hong Kong: "One Country, Two Systems" and Its Real Structural Tensions

Chapters 2 and 7 showed a system in which the party leads and the constitution's text follows. Hong Kong is the test of a different promise: that a region with its own legal and economic system could stay inside that system for fifty years. This chapter covers the framework, the events that strained it, and the 2020 law that changed how it works. It is limited to what the sources I fetched establish. The 2014 events and the 2021 electoral changes are not covered because I did not research them, and I have marked the other gaps.

The Framework

Deng Xiaoping formulated "one country, two systems" in the early 1980s during the negotiations with the United Kingdom over Hong Kong's future. The idea is "one China" with regions that keep separate economic and administrative systems, including their own governments, legal codes, financial arrangements and foreign trade relations.

Hong Kong

Following the Sino-British Joint Declaration, Hong Kong reverted to Chinese control on 1 July 1997. The Basic Law guaranteed its capitalist economy, the Hong Kong dollar, its legal system and legislative autonomy for 50 years.

Macau

Returned by Portugal in 1999 under a similar Joint Declaration, with 50-year protections for its systems.

Taiwan

China has proposed the model for unification and Taiwan has consistently rejected it. One source cites 2025 polls with over 80 percent of Taiwanese opposed (Chapter 9).

The Built-In Tension The Basic Law is a national law, passed by the National People's Congress, that grants Hong Kong autonomy. Chapter 2 showed that the NPC and its Standing Committee are subordinate in practice to the party's leadership. So the guarantee depends on the willingness of the body that granted it to keep it, and the constitution contains no independent court to enforce the limit. This is the structural tension the chapter title refers to; it is an argument from the earlier chapters, not a claim from a source.

2019: The Extradition Bill and the Protests

The 2019 protests began with a bill proposed in February 2019 to amend the extradition law. The trigger was a murder case in which the suspect, Chan Tong-kai, had killed a tourist in Taiwan, and no extradition treaty existed to transfer him. Critics of the bill feared it could be used to send people to the mainland.

Date (2019)EventNumbers
9 JuneCivil Human Rights Front demonstrationPolice: 270,000. Organizers: 1.03 million.
16 JuneSecond, larger marchOrganizers: about 2 million. Police: about 338,000 at peak.
24 NovemberDistrict Council electionsThe pro-democracy camp won by a landslide; the pro-Beijing camp suffered its greatest electoral defeat.
Two Sets of Figures Turnout figures differ by a factor of about four on 9 June and about six on 16 June. Both sets are reported and neither is verified here. Say "police estimated" or "organizers claimed" and give both. The protesters' demands grew to five: full withdrawal of the bill, retracting the "riot" characterization, releasing arrested demonstrators, independent police oversight, and universal suffrage. Two deaths are confirmed in the summary I read: student Chow Tsz-lok and elderly resident Luo Changqing.

2020: The National Security Law

On 28 May 2020 the National People's Congress adopted a decision to establish mechanisms to safeguard national security in Hong Kong. The Standing Committee then enacted the National Security Law as a national law on 30 June 2020.

Four offenses

Secession, subversion, terrorism and collusion with foreign forces.

New body

The law created the Office for Safeguarding National Security.

Reach

Article 38 gives it extraterritorial jurisdiction.

Enacted Nationally, Not Locally Article 23 of the Basic Law envisaged Hong Kong legislating on security itself. A 2003 local bill was withdrawn (the protests of that year are not covered here). The 2020 law bypassed local legislative processes and was imposed as national law, which is the sense in which it altered how "two systems" works. Effects reported by one source include a chilling effect, major Western nations suspending extradition treaties, and mass emigration; I have not checked these effects independently.

In March 2024 Hong Kong passed its own Safeguarding National Security Ordinance, which is the local legislation Article 23 called for. I have not read its provisions, so I do not describe them here.

What "Structural" Means Here

  1. Two lines of authority. Hong Kong's courts and legislature have their own powers, but the source of those powers is a national law that the NPC and party can change or supplement.
  2. A time limit. The 50-year guarantee from 1997 runs to 2047 by simple arithmetic. The sources I fetched do not say what happens then.
  3. Different expectations. Beijing and many Hong Kong residents appear to have understood "high degree of autonomy" differently, judging by the 2019 mobilization; the detail of each side's position is beyond what I verified.
What Is Not Covered I did not research the 2014 political-reform dispute and protests, the 2021 changes to Hong Kong's electoral system, or the treatment of specific prosecutions and media outlets. Those are significant parts of the story, and this chapter should not be read as a complete account of the period.

Hands-On Exercises

Exercise 1

Use the Chapter 2 structure to explain why the Basic Law's guarantee depends on the willingness of the National People's Congress, and say which part of this argument is inference and not sourced fact.

→ Solution
Exercise 2

Report the size of the 9 and 16 June 2019 marches in a single careful paragraph, using both sets of figures, and explain why you would not average them.

→ Solution
Exercise 3

Explain in two sentences what it means that the 2020 law was enacted as national law, compared with the Article 23 route, and name two claims about its effects that this chapter leaves unverified.

→ Solution
