Everyone wants central planning until the appointed central planners do something that disadvantages them specifically. Then they suddenly remember they want national sovereignty to protect their interests from the central planners.
That's how you have massive pro an anti EU splits in the same country. Because central planning tends to produce massive economic gaps between the winners and losers of the planning policies.
That's a problem a much bigger country like China doesn't really face surprisingly, despite having central planners, and despite having plenty of different nationalities! Maybe Euros could learn a bit from them and democratic centralism too
China is only interested in its minorities as a means to promote tourism. Horrible example. Children are put into boarding schools in many places where they are forced to use Mandarin.
It is currently bussing in lots of Mandarin speakers into Hong Kong to undermine Cantonese. It has done a good job of undermining Tibetan as well.
China will destroy or subsume all native culture in every nation/land it gains control of. China is following the Colonial model of divide, conquer/conquest and containment, except this is all happening in the modern era.
India, Bhutan and Tibet are closest neighbours to Nepal, so if Hindi, Bhutanese and Tibetan are taught in Nepali schools are optional languages, it makes sense.
But China is not a neighbour of any of these nations, unless if you admit that China colonised Tibet and it's doing the same to Nepal too.
English is of Germanic/European origin only.
UK is a neighbour of Europe, and was even part of EU for years. Most of USA & Canada are comprised of descendants of UK & European immigrants. USA and Canada are English-majority nations, that were colonised by British and Europeans. So all these nations have the majorly common shared language: English.
But Mandarin is not of Tibetan or Nepalese origin. In fact, their origin is Bharat/India.
China is NOT a neighbour of Tibet, and Nepal. Their closest neighbour, and the one whom they share most of their culture & traditions with, is India.
Tibet and Nepal were subjugated by China, they never welcomed China. China invaded and seized the peaceful Tibet, and systematically dismantled the Tibetan learning centres and cultural centres. Tibetan monks were exiled or executed by China to destroy the Tibetan culture.
Chinese Maoists caused the massacre of the Nepalese royal family, and seized the government after a brutal violent civil war.
China/CCP is using Mandarin (forcibly taught in Tibetan and Nepalese schools) as a weapon to destabilize and destroy the native cultures, language and traditions of Tibet and Nepal. This is why Hindi is no longer the secondary language taught in Nepal schools, even though it makes better economic sense for Nepalese to learn Hindi, due to lots of Indian tourists and cross-border trade with India.
So your arguments don't sway anyone who knows what evils China is doing in these ancient Himalayan lands.
Guess which country colonised India? Yeah, it was Britain. Guess what language the British speaks. No, it is not Mandarin, it's English. But guess why?!
Google for "Macaulay Doctrine" to understand how the colonial British brutally enforced English as the primary language in Indian schools, with evil intention to erode and destroy ancient Indian education system (Gurukul system) and learning traditions (including outlawing the learning of classical martial arts, banning the teaching of Hindu/Sanatani scriptures in Indian schools, banning classical Indian music & arts in schools, etc.).
But thankfully, after India for Independence after centuries of oppression and enslavement/subjugation by Mughal and British, it is ironical that English is not mandatory in Indian schools, and there is stil significant population (hundreds of millions of citizens, especially in rural areas) of India who don't know English (but they know their native language as they learnt it in school as a primary language).
So what China has done in Tibet, Nepal and other lands it has seized, is similar to the evil colonial Macaulay Doctrine, by enforcing Mandarin as a mandatory language in schools, with the evil intent to destroy the traditional language, history, culture.
But Chinese government (CCP) didn't start such native culture destruction in other lands first. It did it in China first. CCP destroyed thousands of classical literature, Chinese Buddhist sacred texts and other traditional knowledge repositories, with the singular evil aim to enforce its own mutated corrupted version of Chinese Buddhism across China. That's why CCP tried to arrest & assassinate the Tibetan religious leader (His Holiness The Dalai Lama; but he managed to escape to India in the nick of time when China invaded and seized Tibet, and he's been living and teaching peacefully in India since then) and when it failed to do so, the CCP brought in its own fake Dalai Lama to confuse and mislead the subjugated Tibetan population.
But this is modern era and Age of Information, so all such evil tactics and corruption of history and culture are getting exposed. World knows what evils China is up to, especially in Asia and Africa.
What's bad? They're being punished if they speak their native language and are taken away from their home communities. No better than the stupid boarding schools minorities were sent to in the west.
I'm not talking about your link. The whole point of those schools is to take them away from their own communities and culture and assimilate them. It's a form of colonialism and the PRC is an empire.
Just Google for "China arrests and exiles Tibetan monks" and "Chinese Maoists Nepali monarchy massacre", and you'll get the answers you don't known here.
In both cases, they still learn their respective language in parallel to Mandarin, which is the national language. So I don't understand how this is evil or smth.
That's how you have massive pro an anti EU splits in the same country. Because central planning tends to produce massive economic gaps between the winners and losers of the planning policies.
