Batteries don't solve the storage problem, but surely you know this.

China is pursuing the strategy you're describing, but there's a reason they're also building nuclear, they're increasing LNG infrastructure, they haven't phased out coal, and they've built a huge amount of oil storage.

Solar and wind can be part of that strategy but it's not so simple, otherwise people would do it

Bateries do solve storage problems. And yes, china energy strategy is based on wind and solar - their portion of China energy production is massively growing.

This opinion is rather simplistic. China is reported to have 60% of it's energy needs already supplied by renewable sources, but this transition creates different types of challenges such as preserving the power grid's inertia. Otherwise you might see yourself in a scenario such as the Spanish blackout. This means having in place strategies for fast response (gas) and baseline (hydro storage, nuclear) to prevent the scenario.
