Not on a verbal sense, but actually doing it.
Is it possible for a country to be completely self-sufficient to isolate itself from the international network these days?
As of the world has advanced into the Internet age, the effects of globalization are extremely mutual beneficial or even multiple beneficial. In an age like this, many poor countries are enjoying the benefits, mostly economic, globalization has brought upon them. The “economic miracle” of China is definitely contributed by the globalization, without globalization, it’s impossible to see what China is today.
And thus, brings the question of the day. Can you deny Globalization?
On a theoretical sense, of course you can deny globalization as you want. The problem is what would happen if you denied globalization?
On this problem, we can go back just a century ago, on the land of Qing Dynasty of China. That was the end of the empire.
Qing Dynasty was the last dynasty in China feudal history, and also a very crippling and prosperous at the same time nation back in 1650-1900. In the late age of Qing dynasty, the Manchurian government practiced the policy of self-sufficiency. There were incredible sea ban policies at the time, restricting people from sailing on nearby water and free trades with international forces.
Only a few, cities were to allow trades with outside regions. Guangzhou, is one of them. And to the very late of 19th century, Guangzhou has become the only one international trading outpost in China. Everything in and out goes through Guangzhou, which effectively gave control to the government on the goods imported.
While this self-sufficiency policy had made China far less behind other powers on the globe.
Thus as you can see the two Opium Wars had made the Qing government bend their knees, and signed treasonous treaties. And the later battles and campaigns happened on the land of China also proved to be the disastrous results of self-sufficiency policy.
Although globalization is inevitable on the course of telecommunication development, this phenomenon still more or less looks like a double-edge sword. It’s forcible, to many nations. While the fast development that globalization has brought upon, developing countries with atrocious infrastructures development can’t really sustain the fast-forward bestowed on them. Many countries are buried in debts, and the economy revival for them is only going to be delayed and slowed down.
