Mongolian Tomsk Problem

[charals]

So as russia i dont know how to declare war to get mongolian Tomsk.

On a previous playthrough I had this problem as well but then one day after some wars with china the substates were free and i could declare war normally.

you should be able to justify a cb on china for a substate region

It's a problem with the puppet system. You have a CB against Mongolia but you can't declare war on Mongolia directly, you have to declare war on China but your CB is not valid against China, so you have to justify a CB against China (acquire substate region) and take the infamy. Or you wait for a revolution in China, or Chinese reunification which will allow you to get your core.

Recently I could normally justify Aquire Substate Region CB and use it to DoW China.
Also if you mean Kyzyl province, then you get it for free by Peking Convention decision. To enact it you just have to sphere Manchukuo. Then you will get both Kyzyl and Primorye region (Vladivostok). You can note that even if you have Manchukuo in sphere, you can still DoW China to conquer rest of Manchuria.
