ABSTRACT
The close of the war and the conclusion of the Treaty of Nanking brought Chinese affairs to the attention of the United States. President Tyler, in his message to Congress, December 30, 1842, cited the British treaty opening some new ports and commented that it provided "neither for the admission nor the exlusion of the ships of other nations. En route to Canton at Nan-hsung, Kwangtung, he met with Chao Ch'angling, a former prefect and expectant ministerial secretary, who had worked with Ch'i-ying at Canton during the negotiation of the supplementary treaty and trade regulations. Cushing felt obliged to send a full account to the State Department of his reasons for abandoning the trip north, although his instructions were merely to use this as a lever for securing a treaty. The Board of Revenue notes that eleven of the fifteen articles concerned with commerce, coincide with existing practice established by the Treaty of Nanking and its supplements.
