On the other hand, my humble opinion is, if China want's to be strong for incoming Unmentionable Showdown with Unmentionable Country, democracy is the No1 thing. More important than J-20 or Type 095. Because, many people in China are ready to trade it's freedoms for prosperity, but what to do when prosperity is gone due to blockade by Unmentionable Country? If they don't get freedom before that, there will be big potential for revolution in case of serious economical hardships/reverses in conflict.
I don't know why you keep pinning your hope on economical blockade. It was tried before and not succeeded.In the 60's US imposed trade embargo on China. with the objective of causing break down and regime change. It doesn't work. It was not lifted until 1972
For your information China is self sufficient in food for a long time . Most of the grain and staple food are produced inside the country.They did import soy and corn for animal feed because raising living standard.
China produced more than 50% of their oil need from domestic sources with increasing import from Soviet Union and Central Asia
Most Chinese electricity comes from coal. Oil is used strictly for transportation.But in recent year China expand the public transport like rail and subway like there is no tomorrow. Most urban center have subway and they are connected with dense railway system and road
So worst come worst people will leave their car in the garage and used public transportation. Inconvenience sure but it will galvanized support for the government
China economy depend more and more on domestic consumption and capital investment . Export component has declined year by year . Export to us is no more than 10%
China is rich in mineral. They are self sufficient in mineral.They did import coal not out of shortage But because it is cheaper to import coal from
Australia than getting it from Shaanxi or inner Mongolia
If embargo was imposed on China, she will suffered but will not kneel down. but the rest of the world will suffer hyper inflation and riot and blood on the street. Embargo is like shooting one own foot
But imposing embargo is act of war and you must be dreaming if it can be localized. It will be the beginning of WWIII.
I doubt that Asian country will support embargo since their own economy is so integrated with China they will suffer immensely. Not to mention they will incur the wrath of China for generations
