I think China was looking at putting up satellite solar reflectors to avoid the electrical cost of night time illumination in cities. If that tech gets cheap enough you could in theory target a town/agriculture like this to give it an effective latitude shift towards the equator.
That doesn't really pass the sniff test... distance to GEO is 36,000 km, the sun is approx. 0.5 degrees in angular size, that would mean a mirror with a diameter of 314 km in GEO. We do not have the technology for that.
