Russia is totally dependent upon China now- to buy its oil and gas and to supply it with manufactured goods it cannot produce itself. Can you name any Chinese ships the Houthis have seriously damaged? The Chinese are very serious about maintaining plausible deniability- they have learned from the CIA. Microchip manufacturing is one reason for reunification with Taiwan no doubt but certainly not the only one. If as you claim the machinery self destructs upon invasion then the west loses that production too. Note- steel works in the east of Ukraine supply 95% of the high purity neon gas required for the highest quality lasers used in microchip manufacture... China is not collapsing- it has enjoyed decades of growing trade surpluses...something no western countries can claim. Name one country that can afford not to trade with China without losing significant economic advantage- just one? SILENCE! China has won the trade war- it pays more for commodities and converts them into manufactured goods more effectively and efficiently than the west can...and that advantage is not easy to reverse and will be impossible to reverse if China succeeds in reverse engineering the monetary hegemony that remains the last real strategic advantage of the already insolvent USA.
