> Also would have been nice to have a critical look at how the Chinese were able to corner the Solar market via state sponsored means.
What would be a critical look though? They thought it would be good to invest in it and so they did, other countries also had that choice if they so wished to sponsor it for strategic purposes but they are ruled by a different ideology which made them decide to not do it.
I don't think there's anything to be critical about, they invested a lot in it and are reaping the benefits.
Should we also be critical about how the Internet started as a state-sponsored project? Many things that aren't commercially viable in its initial state of development need state-sponsorship to get off the ground to be exploited by private companies, the Chinese saw an opportunity for that in solar PV, kudos to them.
I think they meant critical as in a critique rather than a criticism. They are requesting discussion and exploration of the history and ramifications of China's policy, what the meaningful ROI and costs have been, and what the other (4-ish) countries that had the capacity for that sort of investment got out of non-investment (investment in other things).
