MRBM and IRBM Comparison

New MRBM and/or IRBM systems are in development in China, North Korea, Iran, India, and Pakistan. These are strategic systems, and most will be armed with nonconventional warheads. (Both India and Pakistan tested nuclear weapons in 1998.) Russia no longer produces or retains any MRBM or IRBM systems, since they are banned by the Intermediate-Range Nuclear Forces (INF) Treaty, which entered into force in 1988.
