Russians know themselves that after Taiwan takeover it will be their turn for losing Vladivostok.
Really? Are you sure?
1. Chinese and Russian already settled their borders in the signed treaty. In other words, in Chinese official stance, Vladivostok is a Russian city.
2. Why does Chinese want Vladivostok which basically brings no strategic value to China?
How much we talk about Russia-China bonhomie but in reality Russian Nukes and Missiles in Eastern Russia are indeed aimed at China.
That is simply a western propaganda piece shit.
Russian has been expanding her nuclear cooperation with China for decades:
They provided certain nuclear weapon simulation technologies to China;
They are selling nuclear materials to China;
They are working with Chinese on both countries' national missile defense system;
More importantly, both sides have been informing each other the training, deployment and all other activities of nuclear forces.
And don't forget, in West Pacific, there is plenty of US military bases and forces, neither Russia, nor China has spare nuclear warheads or missiles to target each other.
Certainly, both sides have each other's targets in their database, all those missiles can be quickly re-directed towards new targets. But that is a standard protocol of a nuclear power country. Don't be surprise that Russian also has Indian targets in their database.
