DF - 31是目前服役中最先进的弹道导弹，与中国上一代洲际弹道导弹(ICBM)相比较特点是高机动性和由此更好的生存能力。

The most advanced ballistic missile currently in service, the DF-31 features higher mobility and therefore better survivability compared to the last generation Chinese ICBM.

这不奇怪，中国和美国，印度，日本，还有俄罗斯等一些国家，他们都追求长程武器，不只洲际弹道导弹这一个致命优势。

So it is notsurprising China and US, India, Japan, Russia etc, they all pursue the longest range weaponry, not just ICBM to have a lethal advantage.
