Vice-Premier Hu Chunhua stressed the need to clean-up and rectify illegal greenhouses during a national teleconference held for this purpose in Beijing on Sept 7.

The scope of the clean-up and remediation measures must be accurate, Hu said, adding that it is illegal to occupy arable land and transfer it to a non-agricultural purpose, which changes the nature and use of land.

The government will investigate and crack down on these illegal uses, the vice-premier said.

Hu also required relevant officials to stick to the timetable of the operation, and complete tasks at every stage quickly and efficiently.

The main responsibility must be clear, and those who fail to fulfill their responsibilities will face severe punishment, he said.
