Rice not even transported from Andhra Pradesh to Tamilnadu. There are many constraints between state to state. There is no free trading system between states. Only wheat and some other materials come from north. I am not against North Indians, But I dislike their treatment with South Indians. I appreciate you people of north , standing like "chattans" to stop infilters from Pak to other parts of India. I only ask you that just recognise Tamils rights in Sri Lanka.
