Well, if you don't count that parts not coming from this China, comes from that China.
And yes, by far the semiconductor dependence on Taiwan is like another tip of the iceberg thing to the whole process.
Just as American big co extremely naive in thinking that they can replace Chinese labour and factories with Vietnam (whose total industrial output is like one district o Dongguan,) it is equivalently naive to think for mainlanders that they can run away from dependence on Taiwan when even Koreans and Japanese can't do it now (Samsung tapes out a lot of ICs at TSMC and UMC, despite having own fabs for cutting edge stuff)
