The Treaty of Nanking (1842) ended the First Opium War between Britain and Qing China. It opened five Chinese ports to British trade, ceded Hong Kong to Britain, and granted extraterritoriality, making it the first of the 'unequal treaties' and a classic AP World example of economic imperialism (Topic 6.5).
The Treaty of Nanking was the peace agreement Britain forced on Qing China in 1842 after winning the First Opium War. China had tried to shut down the British opium trade, which was draining silver out of the country and creating mass addiction. Britain answered with gunboats, won decisively, and dictated terms. The treaty opened five 'treaty ports' (including Shanghai) to British merchants, handed Hong Kong to Britain, made China pay a large indemnity, and established extraterritoriality, meaning British citizens in China answered to British law, not Chinese law.
Here's the part the AP exam cares about. Britain never formally colonized China the way it colonized India. Instead, it used military victory to rewrite the rules of trade in its own favor. That is the textbook definition of economic imperialism, controlling a region's economy without directly governing it. Nanking was also just the opening move. France, the United States, and others soon demanded similar deals, kicking off a string of 'unequal treaties' that chipped away at Qing sovereignty for the rest of the 1800s.
This term lives in Unit 6: Consequences of Industrialization (1750-1900), specifically Topic 6.5: Economic Imperialism. It directly supports learning objective 6.5.A, which asks you to explain how economic factors built the global economy from 1750 to 1900. The CED's own illustrative example for industrialized states practicing economic imperialism is Britain and France expanding influence in China through the Opium Wars, and the Treaty of Nanking is the document that locked in Britain's gains. It also hits the Economic Systems and Governance themes. China shows you what imperialism looks like when the empire keeps its government but loses control of its ports, tariffs, and legal jurisdiction over foreigners.

Opium Wars (Unit 6)
The Treaty of Nanking is the direct outcome of the First Opium War. If an exam question mentions one, the other is almost always in play. The war is the cause; the treaty is the effect you cite as evidence.
Unequal Treaties & Extraterritoriality (Unit 6)
Nanking was the prototype. Once Britain got treaty ports and extraterritorial rights, other Western powers demanded matching deals, and 'unequal treaties' became the standard tool for prying open Asian economies without formal colonization.
British East India Company (Units 4 & 6)
The opium Britain sold in China was grown in British-controlled India. Nanking is where the threads of British colonization of India and economic imperialism in China tie together into one global trade system.
Meiji Restoration (Unit 6)
Japan watched China get humiliated at Nanking and drew a lesson from it. Rather than resist the West with outdated forces, Japan industrialized and reformed on its own terms. China and Japan make a powerful comparison pair in essays about responses to Western pressure.
Multiple-choice questions usually hand you an excerpt from the treaty itself or a source about the Opium Wars, then ask you to identify the broader pattern (economic imperialism, declining Qing sovereignty, or Western industrial advantage). No released FRQ has used 'Treaty of Nanking' verbatim, but it is prime evidence for Unit 6 essays. In an LEQ or DBQ about imperialism's economic effects or state responses to Western expansion, citing Nanking with two specific terms (treaty ports, extraterritoriality, or the cession of Hong Kong) earns you evidence credit. It also works beautifully in comparison essays, since China's forced opening contrasts sharply with Japan's Meiji-era self-directed modernization.
Both treaties forced an East Asian country open to Western trade, but they hit different countries with different triggers. The Treaty of Nanking (1842) followed Britain's military victory over Qing China in the First Opium War and included Hong Kong and an indemnity. The Treaty of Kanagawa (1854) opened Japan to the United States after Commodore Perry's show of naval force, with no war actually fought. On the exam, match Nanking with China and Britain, and Kanagawa with Japan and the U.S.
The Treaty of Nanking (1842) ended the First Opium War and forced Qing China to open five treaty ports, cede Hong Kong to Britain, and pay an indemnity.
It established extraterritoriality, which meant British subjects in China were tried under British law instead of Chinese law, a major blow to Qing sovereignty.
It was the first of the 'unequal treaties,' setting a template that France, the United States, and other powers quickly copied.
Nanking is the go-to AP World example of economic imperialism because Britain controlled China's trade without formally colonizing it, which directly supports LO 6.5.A.
China's humiliation at Nanking helps explain Japan's Meiji Restoration, making the two a classic compare-and-contrast pairing for Unit 6 essays.
The Treaty of Nanking, signed in 1842, ended the First Opium War between Britain and Qing China. It opened five Chinese ports to British trade, ceded Hong Kong to Britain, required China to pay an indemnity, and granted British citizens extraterritorial legal rights.
No. China kept its emperor and government, which is exactly why the AP exam treats Nanking as economic imperialism rather than formal colonization. Britain controlled trade terms, treaty ports, and legal jurisdiction over its own citizens, but it only took direct territorial control of Hong Kong.
It isn't a different thing, it's the first one. 'Unequal treaties' is the umbrella term for the lopsided agreements Western powers forced on China (and later Japan) in the 1800s, and Nanking in 1842 was the treaty that started the pattern.
It's the CED's flagship example of economic imperialism in Topic 6.5, supporting LO 6.5.A on how economic factors shaped the global economy from 1750 to 1900. It's reliable specific evidence for Unit 6 essays on imperialism and state responses to Western expansion.
Extraterritoriality meant British citizens accused of crimes in China were judged by British courts under British law, not Chinese law. It signaled that China could no longer enforce its own laws on foreigners inside its own borders, which is why it shows up so often as evidence of declining Qing sovereignty.
