I think that notion is based on this reuters reportage.
Nevertheless, IMO PLAAF should work to try to get H-20 into service as soon as possible as a credible deterrence against US intervention. War is terrible for both sides and I think China should do everything in its power to deter any idea of intervention.
How can China kick the US out of the Western Pacific if the US doesn’t intervene. China can’t allow the US to build a ring of fire (intermediate range hypersonic missile bases) around China’s industrial areas along the coast on the First Island Chain.
I still don't see the possibility of all-out war in the next decade, China is still in the phase of developing its economy and transitioning to a fully developed country total war would be detrimental to that and potentially wipe out progress in the past few years. US is still capable of doing great damage even if they couldn't win. IMO with how the economy is worldwide a hot war against the US in the next few years would basically double cook the world economy and it's already a dumpster fire.
Existential threat needs to be taken care of first before economic development. Chinese government has already said 和平与发展 is threaten.
That would be assuming the US play by the rules and don't strike civilian infrastructure for maximum economical damage under the guise of war, I have my doubts about that but hopefully what you said would be the case in a potential Taiwan scenario. But NGL the US have much more pressing matters to deal with for the next decade to be focusing on the SCS, such as saving their own ass from crippling debt
Strike with what? Their bases on the First Island Chain will be under constant bombardment.
