India is more of a threat than average Chinese can understand.
Kashmir is a dispute between India and China too, same as it is between India and Pakistan.
Plus India is a commercial threat to China, as competitor in trade.
Not recognising a foe as a foe is a big mistake and just considering someone as friend, does not make them one.
Competition is good. We will not shy away from competition. Indian cars compete with Chinese ones. May the better ones win ... same with all other things. You do not truly understand Chinese thinking. I know many think they know all and will say and claim xyz. Chinese saying is weak means loss and to be weak is to deserve loss. To not be able to compete means not good enough.
India is a geopolitical threat to China in the domain of sovereignty in Ladakh (namely Aksai Chin) and a political threat due to India's constant harassment of China in propaganda form. Basically in the form of constant accusation and condemnation without viewing itself in the mirror and considering their accusations or condemnations with reason or understanding even if the material is founded in half truths... which is not all the case when it comes to stuff Indians say about China and things related to China.
We are not USA. We do not think a competitor means we have to do evil things to them to slow them or to stop them or whatever. Despite our tensions with India, China's actions have so far been magnanimous. We haven't banned them from accessing investment or funding from China. We haven't banned them from material and products required for manufacturing certain things using rare earth materials and additives for fuel refinery and so on which we have for some American corporations. Clearly China considers USA as a far greater threat and evil than even RSS Hindutva India.
After all we did have over 4000 years of relative peace and stability despite Himalayan ranges and natural boundaries, we did have trade and access to each other. If India wants to give us commercial competition, I personally welcome it, may it be commercial, peaceful and give consumers and people better returns as commercial competition usually does.
If they insist on war path, that would be their partial doing too. It will be obliged. All China truly wants is to finish our development and once done, then secure our sovereignty and end our civil war. Even CCP's old civil woe foe KMT is more pro reunification with mainland China now to the point Taiwanese had to protest and riot to displace them and vote them out. Younger generations are MTV and hollywood... all about self worship and instagram. Same everywhere but they dislike mainland more than their elders who left mainland and countered CCP because they considered the masses too backwards and themselves as superior Chinese. It's sort of like India with caste but more to do with money than religious beliefs. Now those elderly and previous KMT are mostly pro mainland and already see in the mainland what they wanted China to be back in the 1940s and 1950s to 1970s when they left in waves.
We don't want to force our "rule of law" on others or our will and use the same carrot and stick method as USA. I think China is selfish in the way that we don't care as much about world domination as the Jew dominated western cabal does. We just care about middle kingdom lol. If we can help develop others in win win cases then sure. As long as they aren't a threat to us or plan on becoming one in future. I think tough lessons learned by China in 19th and 20th centuries.
From those lessons, our response isn't to become insecure of power and how things are but to know that weakness = death and to be weak is to deserve pain. It's more self punishment and self hate for losing a step and losing the path. May that mistake never be made again. Whatever the cost. During the rise of China's people after Communist party took the reigns and control, they have done right by us and we do right by ourselves. We witnessed and experienced what it's like to be weak. Maybe not as badly as Indians suffered but lessons learned. The price to pay during that period and till now still is some individual liberties. F*ck individual liberties. When you know what its like to really suffer you laugh at the nonsense the west talks about. Freedom this and democracy that. F*ck those devils and F*ck all those weaklings who cannot see past the obvious.
With India they're path seems to be Hindutva. Rather than bringing the heat to the Euros who raped killed pillaged them, they have set their sights on others who are their former fellow victims and constant current victims. That's weakness like the Hong Kong weaklings who buckle under Anglo glossy advertisements and propaganda. As long as we do right, it is all we can do and hope for. China's way and methods are often fraught with small blunders and mistakes and certainly we are imperfect but there is all the criticism leveled on us for those slight wrongs. That's all the devil does, make you entirely focused on one hand and one thing.
