To add on to that, when fighting in the first island chain China will have the support of underwater infrastructure for ASW, something that western media likes to ignore when claiming that their nuclear submarines will have free rein within the first island chain.They claim China has a long-time weakness in anti-submarine warfare. Clearly they don't know what they are talking about. Not when all major surface combatants in the PLAN have variable depth sonar, towed array sonar, and China has a wazoo of ASW aircraft.
