It began over one hundered years ago. The Trans-Siberian rail route from Europe to Harbin, China, was officially opened for regular through-traffic in 1903.
1896: Russia and China signed a treaty authorizing the construction of the Chinese Eastern Railway (CER), which acted as a shortcut across Manchuria (through Harbin) to Vladivostok.
1898: Construction of the CER began, with Harbin established as the administrative center and main construction hub.
1901: The "meeting of the rails" occurred as track-laying teams from the east and west met, effectively completing the physical line.
1903: The route was officially accepted into permanent operation. This allowed for the first regular rail communication between St. Petersburg/Moscow and the Pacific via Harbin.
The railways were similar to the internet and AI boom with the overland connection across the Eurasia continent being a major milestone in human history.
Unfortunately the first period of overland connection wasn't long lived. After the Russian Revolution & Civil War (1917–1924), the railway became a chaotic battleground between "Red" Bolsheviks, "White" Russian forces, and local Chinese authorities. This was followed by Sino - Soviet Conflit 1929 and The Japanese Occupation 1935 which was the final cut of this first regular traffic and connection between Europe and China.
Now, the middle rail corridor is seeing a ressurgence as an alternative to increasingly unstable supply chain routes.
