Evenkiyski District is also east of Central Siberian Plateau, and in part overlap Yenisey bassin.
All indicates that all Soviet TTs on G40 Pacific map are parts of Japanese sphere of influence in Asia as was agreed with Nazi Germany in WWII.
You also get a physical map of regions below.
It helps understand what Narvik meant about adding more TTs between Moscow and Vladivostok in Amur. Distances are so huge in Siberia compared to Eastern Europe.
@Narvik:
I have listened to all 3 of you, General, Baron and K, and again, I tell you the real problem is the map.
The distance from Vladivostok to Moscow is 5 times longer than the distance from Berlin to Moscow, on a real map, or globe.
On our A&A map, from Berlin to Moscow is 5 spaces, and from Manchuria is 7 or 8, depending on the route. It should have been 25 or more to get it right. The Siberian Express, as some name it, favor a historical not correct Japanese Tank drive to Moscow. The only smooth way to solve this, is take a pencil and divide every Russian territory east of Moscow in two, so we get at least 16 spaces between Manchuria and Moscow. Then, the border between Russia and China should be impassable, since the Himalaya mountain range continue into the Hindu Kush mountains, and there are no way a Panzer Army could cross that range. Maybe mountain climbers, but not Tanks.
Now, if everybody in the A&A community do this, the sooner the better, and we start a wave, or a map revolution, in 3 or 4 years from now, the next global 3th edition will have 16 Siberian spaces printed on the official map. Trust me, we the players have more power than we know, but we must use it, and send a message to WOTC. Now, with 16 spaces between Manchuria and Moscow, and impassable terrain between Russia and China, we dont need a derogatory non aggression treaty rule. Every sane Japanese player will see that a Tank drive over that distance is a bad idea.
edit, and I hate this suggestion myself, but if you dont want to use a pencil, another solution could be a house rule that deny any attacking enemy land units to combat move more than 1 space in a turn on the Pacific part of Russia. On every Russian territory, starting from Timgusta to Soviet Far East, all attacking land units can only combat move 1 space each Turn. And the same house rule let Russia non combat move all kind of units with the Siberian Railroad 2 spaces each turn.
