China's solar industry has received an injection of fresh air.

Thursday saw the implementation of new measures that facilitate solar power plants' connecting to the national grid, as well as a Ministry of Commerce probe into polysilicon imports from the European Union. This follows previous similar investigations against the United States and Republic of Korea (ROK).

By tackling illegal foreign dumping and subsidies upstream and stimulating domestic demand downstream, analysts and industry insiders say the moves have offered hope to the struggling solar industry in what are its chilliest days.
