In what could provide India greater strategic depth, the government on Wednesday announced its plan to develop 6,000-km range Agni-IV missile which will be capable of destroying targets deep in China. The announcement is seen as a move to send out strong signals to countries in the neighbourhood. Any missile with a range of more than 5,000 km stationed in south or central India would be out of the range of most capable missiles in Pakistan's arsenal while it would be able to hit targets in eastern and northern China with cities like Beijing and Shanghai in its ambit.
