Which country wanted open trade with china?
britain, united states, france, or russia

Unlike Britain, France, and Russia, the United States wanted to keep trade in china open.
Did that help?

Europe was the first to create trade with China around 1793, because they wished to have Chinas silk, tea, and porcelain, however China wanted nothing to do with such a trade. However, China reluctantly traded their silk and porcelain, but bought nothing in return. 
Today, however, America is also in trading with China. Hope it helped ^~^
