China and Japan were amongst the third world countries not long ago but went into development with the speed of light leaving behind the other third world countries. Both countries went into conscious, planned economy and discipline. Both countries moved from consuming economy to exporting countries. They went into mechanized agriculture, went into science and technology. Today, both countries are industrial super powers. The remaining third world countries are still grappling with poverty,low technology know how etc. The third world countries should borrow from what these two countries has achieved in terms of development.
For me China and Japan invested in their population of which they have so much of and made so much from it. Many third world countries that are suffering now aren't really taking advantage of their human resources potential and this is so important to actually be aware of what puts you ahead of others.
Africa especially have lots of natural resources but still they are backward even with a strong youthful population.
China and Japan will continue to expand economically because they have laid down amazing foundation for them to build on.
