Russian Empire annexes Manchuria after the Boxer Rebellion.

Assuming they somehow manage to not lose this province or only temporarily, What would be the repercussions on:

- Russo-Japanese war?

- WWI?

- Russian Revolution?

- USSR?

- Japanese ambitions in China?

- WWII and Cold War?

- Collapse of the Soviet Union and today’s world?

- Diplomatic relationship with China today?
 
Manchuria north of Sungari was very sparsely populated at the time, aside from, maybe, Mudan river valley, and could be easily colonized by Russians like the rest of the far-east. Especially once the transsiberian is complete. The south is too populated though.
It would depend on whether or not Tsarist government'd use chinese as labour force in the far-east and continue Chuang Guandong. If not you'd see migration in thousands chinese per year as opposed to hundreds of thousands.
The modern Heilongjiang could be an extension of Primorie, as densly populated as european Russia.
For Russia not to loose this province it'd need to either win Russo-Japanese war or reach an agreement with Japan, which would butterfly 1905 Russian Revolution and thus everything down the line aside from WWI, perhaps.
 
What if Russia actually recognised Japanese rule over Korea while Japan recognised Russian rule over Manchuria like Japan at that time attempted to do? One of the casus belli was Russia refusing to acknowledge Japan’s sphere of influence in Korea.

If the Russo-Japanese war is averted this way, could we expect Manchuria to be a full fledged Russian province and later, an S.S.R?

If this happens the Russia will be enemy number one to Britain.

If your going with a Sungari border. Japan didn't go near the upper Sungari during the Russo-Japanese so even if Japan wins, Russia won't lose that land

A bunch of Chinese immigrants are going to come across the porous border, a Manchu SSR would probably have the bulk of the RFE population, come to think of it.
 
Could have a "scramble for China" scenario, with the Europeans taking chunks of China de jure rather than defacto, for example Britain taking Tibet and canton, and the French taking the nearby areas near French Indochina.
