Competition for the licenses was fierce, and the policies severely disrupted trade at Nagasaki, though only very temporarily. No Chinese ships traveled to Nagasaki in 1715-[[1716]], and no copper was exported to China; this caused the price of copper in China to rise dramatically, and though the number of ships permitted to trade was later increased to 40, the total volume of copper imported into China from Japan never recovered, causing considerable losses for Chinese copper merchants. | Competition for the licenses was fierce, and the policies severely disrupted trade at Nagasaki, though only very temporarily.
