«A GUIDE TO THE UNITED STATES' HISTORY OF RECOGNITION, DIPLOMATIC, AND CONSULAR RELATIONS, BY COUNTRY, SINCE 1776: CHINA». history.state.gov. U.S. Department of State. Consultado el 2 de mayo de 2015. «Mutual Recognition, 1844. Formal recognition by the United States of the Empire of China, and by the Empire of China of the United States, came on or about June 16, 1844, when U.S. Envoy Extraordinary and Minister Plenipotentiary Caleb Cushing presented his credentials and met with Chinese official Qiying to discuss treaty negotiations. Prior to this, the United States had dispatched consuls to Guangzhou as early as 1784—the first was Samuel Shaw, the supercargo on the Empress of China—but these had never been formally received by Chinese officials as state representatives. The two countries had acknowledged each other's existence before 1844, but the negotiations and treaty of that year marked the first recognition under international law.»
