Since when did India become a socialist country?

Also, there is a big difference between a socialist planet and a socialist country. China has to tightrope a planet of capitalism that would happily cut them off like it did to North Korea. They have chosen a strategy of improving its society while attracting foreign investment to keep the doors open, and it’s paying off well, as the standard of living for its people increases, and China becomes an essential part of the world economy.
