The US new tariff policy has given the world an important lesson that how important self-reliance is. Today it's USA tomorrow it will be some other super power, it's vital for every country to depend less on big powers discounted rates. There are countries which are doing good despite the fact they don't have good relations with USA but they are self sufficient in producing items to meet domestic needs. This new tariff policy has created more problems for USA as it badly bounced backed and now the world is looking for new frontier of trades where their is less reliance on USA.
Self-sufficient, not dependent on any country. The idea is great and I believe every country thinks of it, but is it easy to implement? I don't think so.
To be self-sufficient requires many factors, that country must have enough resources such as labor, raw materials, energy and especially technology. But look at all the countries in the world, how many countries can fully converge those factors except China and the US? It is not by chance that these two countries are the world's leading powers, everything has its reasons.
Not to mention, to be able to produce cheap goods like China is even more complicated, and so far only China has been able to do that.
Easier said than done, not as simple as we think.
