Not very "ambitious" in my book, especially given their to solar and wind (wind power generation capacity added in the sole year 2016 produced 4%). https://en.wikipedia.org/wiki/Wind_power_in_China
Solar is even more dynamic: https://en.wikipedia.org/wiki/Solar_power_in_China
The language barrier remains low here because China builds with non-Chinese partners (French "Électricité de France" for the EPR, Russian "Atomstroyexport" for the VVER) or at the very least builds local extensions to existing architectures which may be exported and therefore are closely followed by foreigners (Brookfield Business Partners, as the new owner of Westinghouse, and the "CAP" potential series). Even the new (and not yet active) local model (Hualong) is potentially exportable and therefore well documented. Moreover all this stuff is submitted to IAEA inspections, which are well-documented and expose it to international experts.
They had several construction starts in 2015 (some are coming online now), and after a 3 year hiatus began several more in 2019. BTW, I'm not just trusting that Wikipedia table. I've confirmed construction and [near] completion of some of those listed (but haven't bothered with all, my doubts assuaged).
China's nuclear plans were delayed and reassessed. But their commitment to and follow through on their [apparently] revised plan is still quite ambitious. Predictions of the death of nuclear in China were rather premature, albeit understandable considering the lack of transparency, especially in the Western world given the language barrier.
