Following Britain's victory in the First Opium War, the 1842 Treaty of Nanking opened China to foreign privileges. The United States, seeking parity with British commercial and legal gains in China, dispatched diplomat Caleb Cushing to negotiate a formal agreement with the Qing dynasty.
On July 3, 1844, representatives of the United States and the Qing dynasty signed the Treaty of Wanghia at the Kun Iam Temple in Macau. The agreement granted the US all privileges Britain had secured under the Treaty of Nanking, plus additional rights including preferential cabotage and an expanded scope of extraterritoriality.
The treaty established a legal framework that significantly curtailed Chinese sovereignty over American citizens and commerce on Chinese soil. Its terms remained in force for nearly a century until the 1943 Sino-American Treaty for the Relinquishment of Extraterritorial Rights formally ended US extraterritorial privileges in China.
Political Outcome
The United States secured trading privileges, extraterritoriality, and cabotage rights in China equal to or exceeding those Britain obtained under the Treaty of Nanking.
No formal US treaty relationship with Qing China; American merchants operated without guaranteed legal standing.
US citizens in China gained extraterritoriality, preferential cabotage rights, and most-favored-nation status equivalent to British privileges.
