As a matter of fact, we are one. Good or bad, whatever, we are one family. Once we get together, we can work out what we should do for a decent life and I think it'll be more straigthforward for us than uniting some people by force as we're one in deep heart.
I prefer no big mouth but If Outer and Inner Mongolia unifies then population will reach 10 million and world knows what would happen. Not for just world military dominance but New era Mongolia will seek better economy and space exploration and technology and stay solid for green environment. Their fundamental logic is nomad, so they would prefer green solution and fight against global warming. If you have traveled to Mongolia (Outer) then you already know what I mean, because in Mongolia, each yurt has solar energy and yes they have all decent technology TV cable and cellphones etc. Mongolian people capable of living in any environment and their mind is for constantly grow not just like china. That is why China keeps inner Mongolia until today. But sooner or later Tibet and inner Mongolia will (must) separate from China. Because their heritage and costume, culture, language and mind is all different. They are just waiting for right moment. Once China fights itself or with others then they will consider to join Pan-Mongolia. I am telling you the truth. Trust me, Inner Mongolia will be tired of being called chinese. If you are reading this (Inner Mongolians) just prepare yourself as individual and once your Khan recalls you then you should fight for your freedom. Great Mongolians..
Inner Mongolia has NEVER BEEN PART OF CHINA. Relations between China starts from Qing Dynasty. Manchu rulers divided Mongols into two part: Inner and Outer Mongolia. If Outer and Inner Mongolia reunites, Mongolia will become one of the biggest nations. But there is also one big thing to consider about: China roughly dictators many Mongols and Tibetans, and blocking their democracy, just for some strategy and economic reasons.
If inner Mongolia was united with outer Mongolia it would only make it a stronger country. It is hard when parts of a country are not united. Unification is almost always a good thing, and this is definitely the case for Mongolia. I would love to see inner and outer Mongolia united.
Mongolia should be unified, if the people in the two regions desire unification. But areas that have be expropriated by China (more so true with Tibet) offer up a sticky determination of rights. China moved in tens of thousands of ethnic Chinese (Han?) to Tibet (not sure about Mongolia), so do those newer residents have the right to also determine the regions status. So yes, Mongolia should be unified, if the people desire it, without interference from the Chinese central government.
They are different branches of Mongolians, speaking very different languages. The writing are different now. Outer Mongolia has abandoned their traditional writing. That's why they end up with two different regions. If unified, they will compete for leadership. One is bigger but less population and less developed, one is smaller but more people and wealth. Even unified they will also distinguish themselves with each other.
