Treaty of Wanghia with China
3 Jul 1844
Causes: The US began trading more and more with China and other Asian countries due to new technological advances and an increased desire for new markets and resources (tea, porcelain silk) from the Market Revolution.
People: Caleb Cushing, President Tyler
Effects: The treaty was the US' first diplomatic agreement with China and an example of early US imperialism in Asia. American trade with China increased and led to hopes of the same happening in isolated Japan.
