One of the main strategic goals of China is to not be reliant on oil/gas, because they have none. They have to import almost all of it(from Middle East) and if war happens, that would be a major strategic liability.
It is easier to get things done in the name of “national security”, instead of in the name “humanity’s survival”. A national security issue threatens the very existence of the state, humanity’s survival is too vague and who cares if it exists in the future, as long as the state survives.
Europe(and other countries), needs to act with the same urgency as China when it comes to the electrification of vehicles. Especially since there are actual national security issues that are caused by climate change(and potential chinese dominance in electric vehicles).
China has low proven oil reserves(per capita). Obviously they have some, it is a big country. They are also using shitload of oil. It isnt about how much you have, it is about how much you have in comparison to how much you need. Check oil imports by country. They are importing 2x+ more oil than they produce.

But the main issue isnt that they are importing oil, almost everyone is importing oil. The main issue is that their oil imports might be vulnerable if they decide to invade Taiwan and the US blockades the Strait of Malacca. And taking over Taiwan is a major priority for the current chinese administration. In 3-5 years, things will start getting pretty hot.
Yes, because thats when they embraced capitalism, opened to the global market, WTO, etc. What followed was a massive industrialization of the country(actual industry, instead of farmers melting pots in their backyards), hence the demand for oil skyrocketed.
