There is a significant difference in term of dependency when it comes to solar vs gas/oil. Solar panels are not consumables when int comes to energy production- oil and gas are. China can shutdown the supply of solar panels, but not the energy generation with existing panels. This gives you time to start building other supply channels.

I don't agree. Oil and gas can be sourced from many different countries, you don't have to rely only on Russia. Russia is just the obvious choice if you are in the middle of Europe, but there are many other producers.

If China stops the supply of solar panels today, you are only good if you have already achieved 100% energy needs coverage with solar. No large country is going to be at that level anytime soon.
