SCMP: China showed off its nuclear second-strike capability – the ability to hit back after an enemy launches an initial nuclear attack – just two days before US Secretary of State Antony Blinken’s visit to Beijing and Shanghai. 南華早報記者：就在美國國務卿布林肯訪問北京和上海的前兩天，中國展示了二次核打擊能力，即在敵人發動首次核攻擊後進行反擊的能力.

On Monday, the Chinese navy released rare footage of the launch of a JL-2 ballistic missile from a nuclear submarine. The video shows China’s Shandong aircraft carrier fleet, including four submarines, during a simulated exercise.

Near the end of the video, a ballistic missile is shown being launched after a narrator states that “the submarine has arrived at the scheduled launch location … and is commanded to carry out a fatal strike”.
