Foreign trade is concentrated at Guangzhou
In the mid-eighteenth century, Qing arrangements concentrated major European maritime trade at Guangzhou, with 1757 an important turning point. Authorized hong merchants handled transactions amid restrictions on residence and contact. The port connected producing regions supplying tea, silk and ceramics with distant markets. Customs, officials and intermediaries managed revenue and responsibility. Seasonal sailing and procedures shaped commercial practice, making the port a continuing setting for negotiations between different interests.
Local labour beyond the hong merchants
Warehouses, loading, ship repair and provisioning depended on porters, craftsmen and shops. Tea and silk underwent purchase, processing and transport before shipment abroad. Credit, accounts and interpreters supported merchants, while disagreements involved prices and legal responsibility. Many workers sustained daily operations beyond the leading intermediaries. Commerce changed urban consumption and spaces, bringing long-distance exchange into household livelihoods through particular jobs performed on ships, docks and streets.
Conflict and institutional change
Demand abroad, silver flows and opium smuggling increased tensions. Qing officials, traders and the British government held conflicting expectations of control and negotiation. Military conflict followed. The Treaty of Nanjing in 1842 ended the hong monopoly and opened additional ports, displacing the earlier system through imposed terms. Trade continued under altered jurisdiction and power, with local merchants and workers adapting their activities to changed markets, with treaties and jurisdiction placing commercial expansion within new political relationships imposed through the outcome of warfare.
