Interesting New Edict From Beijing

I'm sure I'm not understanding this correctly.

The State Council, China's cabinet, has released a circular banning the production, sale and use of super-thin plastic bags in China beginning from June 1, 2008, Star Daily reported (in Chinese). The circular set a thickness standard for plastic bags at 0.025mm, and required that retailers stop providing free plastic bags of any thickness to their customers. The State Council called on related authorities such as the Administration of Quality Supervision, Inspection and Quarantine and the State Administration of Industry and Commerce to make a joint effort to enforce the regulation. Violators of the rule could face fines and public shaming, as well as confiscation of the bags.

What exactly are retailers supposed to use? Paper bags? There are no trees in China.

Plastic bags are much more prevalent in China than in the US. Every vendor at the fabric market, the local fruit stand, the grocery stores, the small shoe stores on the street, the veggie markets - every vendor uses them. And reuses them. Other than a few grocery stores, I've never received a "new" plastic bag. Are we forced to start paying for used plastic bags? What price do you charge? Do I have to negotiate?
