China doesn't want to rely on gas because they have to import it. They're fine relying on coal, which they can produce reliably, which is why they keep building coal-fired plants.
Germany has the same reliance but Europe broadly hasn't done anything about it, substituting piped gas from Russia with shipped gas from America. (Which, unfortunately, is their only option absent re-firing coal or turning on nukes.)
