Then & NowPelt and road: how trade with China was smoothed with furs from British Columbia
Sea otter pelts were one of few commodities the Chinese actually wanted in the 18th century, but overexploitation and cheaper rabbit fur from Australia put an end to what was a profitable trade within decades

Vancouver has been a popular emigrant destination for Hong Kong Chinese for decades, and migration to Canada’s west coast accelerated in the 1980s and ’90s as the territory’s 1997 return to Chinese sovereignty loomed. Many Hong Kong residents scrambled to obtain a foreign passport, then decamped for home almost as soon as their “back-pocket insurance policy” had been issued.
The large-scale influx into Canada – and Vancouver, in particular – was not without teething problems; to some wits, the scenic British Columbia city became known as Van Kong, or Hong-couver, due to its sizeable Hong Kong Chinese migrant population.

A key problem for traders attempting to establish commercial links with China was finding something Chinese consumers actually wanted, and could afford to purchase in sufficient quantities to make their importation economically viable.
In addition, trade goods had to be something China was not in a position – either through lack of natural resources, an inappropriate primary production climate, or want of technology – to manufacture domestically.
