Fur exports from North America to China were the major reason for the European exploration of western North America in the 17th and 18th centuries, and into the earliest 19th century. The Chinese elite used fur pelts to line their robes. Sea otter, which has the highest follicle density of any mammal, was the most favored (and I believe imperially mandated for the highest ranking mandarins) and the pelts were incredibly valuable. The Spanish and English exploration of the Pacific Northwest was largely done by trade expeditions which would trade various goods for pelts with the various Native tribes, and then sail to Canton to trade the pelts for Chinese goods. The Russians more or less enslaved some of the tribes of the Aleutians (the Unangan people) and brought them as far south as central California in their trade ships; the Unangan hunters hunted from sea kayaks by day.

Both the North West Company (British) and John Jacob Astor (US) set up transcontinental overland trade networks in the late 18th and early 19th century focused on the fur trade, with China being a primary customer for pelts.

I think in the first few decades of the 19th century, Chinese Imperial fashions changed and much of this system collapsed, although not fast enough to prevent the near-eradication of the sea otter population.

A good pop history of the US Overland component is Astoria by Peter Heller. It is also addressed a bit in more scholarly work such as the Columbia's River: Voyages of Robert Gray, by J. Richard Nokes.

That’s fascinating I never considered before what the fur traders out west were doing. That’s an aspect of history left unexamined usually.
