Oh yeah about China, although an interesting nation with a very long history of fracture and unification, great cultures, interesting ideologies, and etc, China nowadays is within a spot which is mostly ruled by the "Socialist Peoples Republic Of China" called communist china in which we call the actual China, and the island Taiwan "Peoples Republic Of China" is now really an empty void of culture, although religion does happen there as usual, it's not common nowadays since all of that has gone away long ago. This leaves China having a high atheist population today, and also having a huge void within the culture world, since most of that culture has been destroyed or lost by Maoist China during the revolutions.
China also has it's own internet, due to the communist rule within China, outside internet around the world is restricted for them, unless if used by some bypass in which usually happens all the time in china. There's basically 2 types of internet within this world now, the western internet, and the communist party of China internet.
The social credit system is at high there ever since its establishment not too long ago. The social credit system monitors most or all citizens within the country by the use of cameras, social, media, and etc, with the inclusion of facial regonistion technology, and many more so onward.
Interestingly enough, China censors a lot of stuff which are just related to military and test things just like the western world, but not only do they do this by hiding secret military bases and things, they also hide things in which are mainly dark, such as the ughyur concentration and reeducation camps within the xinjiang province of China, and other things in which are related to some many things in which I can't explain here since I have a lack of information about them.
These are just some of the bad things explained about China really, so yeah, thats it, goodbye.
But wait, theres more, but I wanna focus onto if the world was dependent on China, let's find out.
So China has ton of potential to become the hegemon and global superpower of the 21st century. Let's pay attention to geography first. Within the east, they have ocean. The West has deserts and the highest mountain range the himalyaas, the South which is just jungle,a nd the north which is just the Siberian cold front. This gives them a kinda isolationist geography, and this has happened countless times throughout history, which China stayed isolated from the world for hundreds or even thousands of years till we came by and caused a lot of things to happen there. But having geography like this can be great, since you're mostly protected in almost every direction with mountains to the west, and occan to the east.
The advantages of China's geography is that of the Tibetan plateau. The Tibetan plateau has a lot of water, and once you own that, you have control of that water. This is important for China since they can now have control over their major rivrs such as the yellow, and yatzee rivers in which they thrive on. But this gives them an advantage to block rovrs from southeast Asia and India, since the great rivers that flow from both India and southeast Asia come from the Tibetan plateau, such as the ganages, Indus, and menkong rivers. If China managed to block those rivers from those countries, they'd had control over their water supply. If they retaliate against you in the future, you could just suffocate their populations by drought by damming their rivers and they'll die in the thousands or evem millions. This can also give China some allies or make the now water dammed country a puppet state if managed to do so.
China also has huge manpower, over 2 million soldiers, more than the United States of America, and has a large military. China currently has over 200 nukes, although due to the censorship of China, they may have more than must 200, maybe 500 or even a thousand. But we'll leave nukes out since they're world ending things. They do have a good naval force but it isn't as widespread as the United States is, since China doesn't have control of many islands around the world except the islands within the South China sea. They're now setting up basses there which are artificial islands with military bases on top of them, so that they could gain control over the sea, and also the resources such as undiscovered oil and other things. If they manage to control the area fully, they'll be technically unstoppable since they'll have all of the oil to themselves, and a,so use it to fuel their military.
Right now, China is getting close to becoming a world superpower, and within the next possible 10 years if the United States doesn't do anything about it, China would fully become the dominant world superpower.
So how to dominate the world as China, well you'll have to do a lot since its gonna take a while to explain here.
Don't invade Taiwan as of yet, just wait till the United States just gives up on it and leaves Taiwan defenceless when you become a global superpower. Once so, you must dam India's rivers to make India a puppet state, since India is a US ally, but not only that, if you control India, you'll now have a huge vassal of people to have, since India has over 1.3 billion people (as of now) and if controlled by you, you literally have now control to barely 1/3rds of the worlds population. Leave america alone but expose America with its real ongoing so everyone that would lose faith in humanity there and would just give up on the United States. If Russia were to collapse you must anexx Siberia since it has a lot of area for your giant population to move there,a nd also has a lot of untapped resources such as oil, copper, gold, coal, diamonds, and etc. Mongolia must not exits, it must be anexxed just like Tibet. Censor more of your ongoing such as genocide, assimilation, and etc just in case. And finally become a dominant world power. Unstablize the European powers till they just go to your side or just collapse.
So yeah, you've managed to dominate the world, and guess what, how the timeline looks like would be similar to that of George orwells book of "1984" althoigh with no history eradication nor other things really.
