Parsing South Korea’s Estrangement From China

In July, the US Ohio-class ballistic-missile submarine (SSBN) visited South Korea for the first time since 1981. Not one, but two of the 560-foot-long warships—which carried a payload of 24 long-range Trident ballistic missiles—surfaced in South Korean waters (Korea JoongAn Daily, July 24, 2023). From Washington and Seoul’s perspective, the SSBN deployment was a pointed reminder to the mercurial North Korean regime to exercise restraint, but the symbolism of the SSBN visit was not lost on China—Pyongyang’s closest ally. For all its military modernization efforts, Beijing has no effective defense against the Ohio-class sub.
