The part often glossed over is that while the U.S. and Russia both have large oil reserves and domestic production capabilities, China has virtually nothing in comparison. Their production is about 1/4 that of the U.S. despite having 4x the population, meaning that per capita, they have < 1/16th the oil available. Electrification is a matter of national security for them, because any major global geopolitical conflict (say, the escalation of the Russia/Ukraine war, or a Russia/US conflict, or more turmoil in the Middle East) will cut off the flow of oil imports and grind China's already-weakened economy to a halt.
Follow the incentives and you can predict the outcomes.
