Our system has not been Communism for 30 years.
We had market reforms in 1978.
Our system is called "Socialism with Chinese characteristics", which Western observers label as State Capitalism.
India though, the system is copied pretty much directly from the British Parliament, and you guys even use English in Government and state to state communication.
If the Tamil Nadu Government wanted to communicate with the West Bengal Government, they would use English. If an Indian Tamil citizen and an Indian Bengali citizen want to communicate, they use English.
In China, all province to province and Government communication takes place in Chinese, and when Chinese want to talk to people from other regions of China, we use Chinese.
