It's not a bad thing if this is mostly just restoring forests ravaged by bad policy, but it's a bit odd to compare this reforestation, quantitatively, to what's going on in countries that didn't have a "war against nature".
My second thought is how badly Chinese communism must be doing that they need such a massive effort in order to prevent their citizens from accessing information and voicing dissent. We are lucky to be living in such a free society. Internet seems to be losing the battle against government interference and censorship and that is more of a bad thing then a good thing.
China relies heavily on export, so they can't just block everything. There are tons of proxy services to bypass GFW in China, and most of them have government background.
