Oh My goodness, just see how the two other great power RU and US deal with these sort of things. Go educate yourself
UK and FR are not going to fight with CN. They preparing to support US in a war with CN, not going to directly involve themselves.
Russia and U.S. two countries each with their own distinct histories not to mention in how they each employ military application(s) with respect to what they deem as their strategic A.O.R. The U.S. a country that's been unscathed with the savagery and ravages of war on the scale of destruction happened in WWI and WWII act can go around the world with it's military forces largely immune from the psychological effects from such devastation which obviously results in their cavalier intentions to use nuclear weapons be it tactical or otherwise. China for a lot of the posters here knows first hand the brutalities and savagery of war first hand and the humiliation of subjugation that comes after it's defeat. Therefore it's military use of force and it's subsequent military strategies has always been about "Active Defense" it's not interested in taking an inch of land or territories from other countries all she wants is strategic space and buffer from it's adversaries i.e. Korean War, 1962 Indian border war, Sino-Soviet skirmish, Sino-Vietnam War of 1979.
Russia under the leadership of Putin learned it's bitter lesson ever since the dissolution of Soviet Russia when it tried so hard to be liked by the west, adopting whatever "shock doctrine" economic prescriptions then Jefferey Sachs and his economic acolytes pushed much to the detrimental effects towards Russian people which saw a massive dropped with their life expectancy and the humiliation it wrought upon them. Putin reversed that but the west led by the U.S. doesn't seem to want to understand and appreciate Russian "history" because it subsequent actions bear fruit from the NATO expansion, the Georgian 2008 war, the Ukraine 2014 coup which precipitated the annexation of Crimea and the breaking away of Donbas republic.
You asked me to look into Russian actions, well their actions of waging war against Georgia in 2008 - defeating then Pres. Shalikashvilis misadventures in South Ossetia - defeating the American trained and equipped forces in 5 days did not prevent other countries within her periphery to lean more towards the west side now did it? Otherwise, as I pointed out, the 2014 Maidan incident wouldn't have happened and the subsequent too numerous to count sanctions that's been leveled against Russia making her economy not exactly the envy of Europe.
What the Chinese is doing is obviously different for geopolitical, geographical, and economic reasons. And I for one prefer their greyzone tactic that adopting either the Russian approach or the American approach which doesn't show any semblance of some kind of winning strategy other than it keeps on threatening to blow up the entire planet if she doesn't get her way i.e. Cuban Missile Crisis, 1958 of nuclear preemption plan against both the Chinese military and Chinese civilization.
Now, how about you actually elucidate us with your grand strategic plan or understanding of current Chinese geopolitical and military challenge and distill it to us in such a way mental midgets like myself can easily digest to understand.
