Did China Close Off Trade? Historical Fact Check

China Never "Stopped Trading with the World"

The premise is a historical misconception. China has never completely ceased global trade.

• Imperial Era: Trade restrictions existed (Canton System, 1757–1842), but silk, tea, porcelain flowed via Canton (Guangzhou) and overland Silk Road.
• 1949–1978: Maoist era limited trade to socialist bloc, but still traded with non-aligned & Western nations (e.g., grain from Canada/Australia).
• Since 1978: "Reform and Opening Up" made China the world's largest goods trader (WTO member since 2001).

No single city was "the only one open" in a total closure scenario. The Canton System designated Guangzhou as the sole port for *Western* maritime trade for a period, but trade continued elsewhere.
