The Sino-Russian Border and the Treaties China Calls Unequal — and Russia Calls History

Unfinished Business: China’s History with Russia’s 19th-Century Treaties

China’s relations with former colonial or imperial powers vary widely, and its willingness to “forgive” or move on from historical grievances depends largely on whether issues were resolved through diplomacy or war. With Britain, France, and Japan, modern relations were recalibrated after territorial issues were settled. With Russia, the situation is more complex because the territorial changes of the mid-19th century—primarily the Treaty of Aigun (1858) and the Convention of Beijing (1860)—were never formally repudiated or reversed, and their legitimacy remains a subject of historical discussion inside China.

China in the Early 19th Century

At the start of the 1800s, the Qing dynasty governed one of the world’s largest economies, significant in population and cultural influence. However:

  • China’s military technology lagged behind rapidly industrializing European states.
  • The court maintained restrictive trade policies at places like Canton (Guangzhou).
  • Western powers increasingly sought commercial access, particularly for tea, porcelain, and silk.

Opium Wars and the Shift in Power

Britain’s desire to balance its trade deficit with China led to expanded opium shipments from British-controlled India. The Qing government’s attempt to stop the opium trade in 1839 contributed to:

  • First Opium War (1839–1842) → China defeated; Treaty of Nanjing ceded Hong Kong and opened several ports.
  • Second Opium War (1856–1860) → Anglo-French forces captured Beijing; the Old Summer Palace was looted and destroyed.

These conflicts weakened Qing authority and accelerated foreign encroachment into China’s coastal and inland regions.

Territorial Pressures from Multiple Powers

During the same period:

  • Britain aggressively consolidated influence in southern China.
  • France expanded its reach in Southeast Asia.
  • Germany and the U.S. acquired treaty rights and concessions.
  • Japan modernized rapidly and later defeated China in 1894–1895, taking Taiwan.

China was not colonized outright, but it was divided into multiple spheres of influence, with foreign states seizing and controlling ports, trade, and infrastructure.

Russia’s Expansion in the Far East

While China fought wars in the south, Russia was expanding eastward across Siberia. Russia’s goals included:

  • Securing access to the Pacific
  • Establishing warm-water ports
  • Consolidating empire-building efforts started under Peter the Great and continued by the Romanov dynasty

Treaty of Aigun (1858)

Signed between Qing official Yishan and Russian representative Nikolay Muravyov-Amursky, the treaty:

  • Reassigned lands north of the Amur River to Russia
  • Established joint control over land east of the Ussuri River pending later clarification
  • Was signed under significant pressure while China was already engaged in conflicts with Western powers

Convention of Beijing (1860)

After Anglo-French forces advanced into Beijing, Russia mediated negotiations—but also obtained:

  • Full control of territory east of the Ussuri River, including the area where Vladivostok was later founded in 1860
  • Formal recognition of the earlier territorial changes

The combined area transferred to Russia in 1858–1860 is often cited as more than 1 million km², though estimates vary depending on definitions.

Why China’s View of Russia Differs

With Britain, Japan, and France, major territorial disputes were resolved in the 20th century:

  • Hong Kong was returned by Britain in 1997.
  • Japan withdrew from China at the end of World War II.
  • France ended its colonial rule in Indochina after 1954.

In each case, foreign occupation or control ended, and formal agreements recognized new borders.

Russia, however:

  • Retained all territory gained in the 1850s–1860s
  • Did not renegotiate border treaties
  • Viewed the agreements as legally binding and final
  • Continues to administer the Russian Far East, including Primorsky Krai and Khabarovsk Krai

China’s Position

Modern China does not officially contest the current border, which was reaffirmed through a series of agreements:

  • 1991 Sino–Soviet Border Agreement
  • 2004 Supplementary Agreement, settling remaining river-island disputes

However, Chinese education and historical scholarship still refer to the 19th-century treaties as “unequal treaties” signed under coercion. The idea of “lost territories” appears in Chinese historiography and public discourse, though it is not an active policy goal.

Modern Geopolitics

Despite underlying historical tensions, China and Russia today maintain a strategic partnership driven by:

  • Shared concerns about U.S. hostility
  • Energy cooperation
  • Military coordination
  • Diplomatic alignment in the UN Security Council

However, analysts often describe the partnership as pragmatic, not rooted in deep historical trust.

Demographic and economic trends—such as Chinese migration and investment in the Russian Far East—occasionally raise concerns among Russian commentators, though official Russian policy does not frame this as a territorial threat.

Long-Term Questions

Scholars debate several issues:

  • How historical grievances might influence future Sino-Russian relations
  • Whether demographic or economic shifts could alter dynamics in the Far East
  • How changes in Russia’s political stability or global power might affect the relationship
  • How the United States and its allies would respond if Sino-Russian cooperation weakened or tensions rose

Most mainstream experts emphasize that China is not pursuing territorial revisionism against Russia today, but historical memory continues to shape public attitudes and long-term strategic thinking.
