China has a habit of increasing its solar power targets. I think it's done so 3 times in the past year and a half. Its initial 2015 target of about 5 GW has been quadrupled to 21 GW in that time (see the link above for more info on that).
China is about to double its targeted installation rate for solar PV for the second time in as many months, and now expects more than 40GW to be installed by 2015.
What can rest of the world do to increase Solar and other renewable energy mix?
