Britain’s huge advantage economically was its early development both of a coal industry and of a seaborne coal trade. Hong Kong’s big disadvantage is that had few natural mineral resources and no coal. As Britain aggressively expanded its empire in the mid-19th century, it could do so using steam ships supplied with coal from Britain.

We can see that at work in a wonderful infographic created by the father of such things, the French engineer Charles-Joseph Minard, who illustrated Britain’s global coal export trade in 1850, 1860 and 1864, by which time 64,000 tons of the stuff were coming to HK. That expansion along with the number of steam ships, meant the problem of getting the coal the 14,000 miles from Britain around the Cape of Good Hope to places like Hong Kong got worse.

The obvious answer was to find coal nearer to the places that needed it and we can see efforts to that end almost as soon as the dust had settled from the 1st Opium War. There’s evidence of some of the earliest coal being mined in Australia being imported by the early 1850s. So did coal from the on-again, off-again mines from the deposits in Labuan, first discovered in 1847. Coal from Keelung in Taiwan was arriving in Hong Kong by the end of the 2nd Opium War. In the early 1860s there’s even coal recorded for sale from the Lackawanna mines in Pennsylvania, USA, as well as from Canada and New Zealand. The first coal from Australia arrived in Hong Kong in the 1840s, but was a sporadic arrival until more regular shipments in the 1870s through 1880s. From that last decade onwards more and more of Hong Kong’s coal came from Japan to the point that by the mid-1890s it was Hong Kong’s main supplier. Coal from North China only began to make a serious contribution by the 1920s.

That was until WW2, when everything changed. Post-war, that as from the 1970s has seen HK’s most recent coal high, ten times the amount of coal used in Hong Kong’s first century have fuelled Hong Kong’s growth engine, the main sources of the coal being South Africa and Indonesia. All up, in modern Hong Kong’s 180 plus years of existence, not far off half a billion tonnes of coal have arrived to fuel its growth from all over the world.
