Treaty of Nanking - Aftermath and Legacy

Aftermath and Legacy

Since the Treaty of Nanking was brief and with only general stipulations, the British and Chinese representatives agreed that a supplementary treaty be concluded in order to work out more detailed regulations for relations. On 3 October 1843, the supplementary Treaty of the Bogue was concluded at Bocca Tigris outside Canton.

Nevertheless, the treaties of 1842–43 left several unsettled issues. In particular it did not resolve the status of the opium trade. Although the American treaty of 1844 explicitly banned Americans from selling opium, the trade continued as both the British and American merchants were only subject to the legal control of their consuls. The opium trade was later legalised in the Treaties of Tianjin, which China concluded after the Second Opium War.

The Nanking Treaty ended the old Canton System and created a new framework for China's foreign relations and overseas trade which would last for almost a hundred years. Most injurious were the fixed tariff, extraterritoriality, and the most favoured nation provisions. These were conceded partly out of expediency and partly because the Qing officials did not yet know of international law or understand the long term consequences. The tariff fixed at 5% was higher than the existing tariff, the concept of extraterritoriality seemed to put the burden on foreigners to police themselves, and most favoured nation treatment seemed to set the foreigners one against the others. Although China regained tariff autonomy in the 1920s, extraterritoriality was not formally abolished until 1943.
