China did very well in education & infrastructure before opening up to the world in 1979. They had many scripts and languages, which were replaced by one Chinese script and language by Mao. Now everyone takes part in the country's development. In India, only 7 - 8% of people, knowing good English matter, others r second class citizens in their own country.
China also introduced one child norm forcefully in 1979, controlling the growth of population, otherwise there would have been many more crores of people there creating chaos. We also must enforce one child norm, without adopting vote bank politics for appeasing some minorities.
