In 2013, an updated edition of a standard text on Chinese military strategy, partially translated by the Union of Concerned Scientists, said China’s nuclear forces will move towards a “launch-on-warning” posture, where “…under conditions confirming the enemy has launched nuclear missiles against us, before the enemy nuclear warheads have reached us… [we can] quickly launch a nuclear missile retaliatory strike.”
China, for instance, has around 25 DF-31A ballistic missiles with a range of 11,000+ kilometers. In other words, the ability to hit targets in the US. India has an undisclosed number of Agni-5s with a 5,200-km range, good enough to hit significant targets in China. However, the bulk of the arsenal is short range, clearly with Pakistan in mind. India is also trying to create a nuclear triad, but the report says it is still limited to short and mid-range with longer range missiles still a few years away.
India’s willingness to sign the Hague Code of Conduct Against Ballistic Missile Proliferation “shows that such leverage can be effective given New Delhi’s ongoing campaign to secure the benefits of membership in the Nuclear Suppliers Group”.
