I had a personal connection to the Amur River which is why I read this book. Way back in 2000, my wife and I traveled to Birobidjian to adopt our son, arriving and departing via Khabarovsk, a major city in the Russian Far East on the banks of the Amur. So, I have actually seen the Amur (for what that is worth)
The author set out at around 80 (!) to travel from the headwaters of the Amur in Mongolia to its mouth at the Sea of Okhotsk. This involved traveling on horseback (Mongolia), then various forms of motor transport, and a few times, on the actual river itself. As the Amur demarcates the border between China and Russia for a large segment, there were all sorts of low grade tensions to navigate, as it were.
The author is an outstanding writer, able to lyrically paint pictures of both the scenery and the inhabitants. As he spoke Russian and some weak Mandarin, he was able to converse with his guides, drivers, innkeepers, and the like. The trip took place just before COVID halted all forms of tourism in this part of the world. By my standards, lodging and food were execrable - but Thubron never complains - if anything, these kind of trips is his reason for living.
As Thubron recounts his journey, he makes a point of visiting spots of historical interest - all but unknown to Americans. And, at each site, you get a mini-history lesson over the competing claims for this territory - where, in the 1850s, the weak Manchu Empire lost its claim to the lands north of the river. The whole period between 1600 and 1900 is a period not too dissimilar from the westward push by Americans (except in this case, it was an eastward push by Russians). Fortunes were won and lost and there were promises of riches to be had by developing a port on the Pacific and linking the Amur basin with Pacific trade. Sadly, the Amur wasn't easily navigable and, of course, in the winter, it froze solidly.
There are whole bunches of atrocities, mostly committed by the Russians against the Chinese over the decades (none of which I was aware of). There is a simmering sense amongst the Russians that their land is being exploited by Chinese timber and mineral companies in league with corrupt Russian magnates. Oh, right - and then there was an extensive legacy of gulags in both Czarist and Soviet times.
Thubron makes a point of seeking out indigenous communities, where the original language is all-but-forgotten.
All in all, a fascinating story and compellingly written. You'll learn a lot and get a good geography lesson while doing so. As I read this during month two of the Russian invasion of Ukraine, the one-on-one conversations Thubron had with ordinary Russians helped illuminate the hold that Putin has on the mindset of the population - especially the feeling of victimhood and inferiority versus the outside world. Not everyone, but often enough. Young people want to move and many communities are slowly dying out. Even the Chinese in their northern border cities would much rather be in Beijing or Shanghai. A strategic land, beautiful, but with a harsh climate.
An excellent map that pinpoints each location of note in the text. Sadly, no photos.
