     China had decided to take action to stop the use of plastic bags. Supermarkets, shops and outlets (经销店)

in China will not be allowed to hand out free plastic carriers and all plastic carriers must be clearly marketed

with prices from June 1.

     "People use too many plastic bags every year and fail to deal with them properly, wasting valuable oil and

littering the country," China's government said in a statement.

     While providing convenience for consumers (消费者), the plastic bags have also caused serious pollution

and waste of energy and resources.

     "We should encourage people to return to carrying cloth bags, and using baskets for their vegetables." the

statement said.

     In addition, the production, sale and use of bags less than 0.025 mm thick is banned from the same date.

The firms that break the rules will face fines or confiscation (没收) of goods and profits (利润).

     China also said it would consider increasing taxes (税) to discourage the production and sale of plastic bags

and encourage the recycling industry.

     Rubbish collectors have to separate plastic for reprocessing and cut the number of plastic bags that are

burnt or buried (掩埋).

     The move brings China into line with a growing international trend (趋势) to cut back on the use of plastic

bags. From Ireland to Uganda and South Africa, governments have experimented with heavy taxes, with the

aim of getting rid of plastic bags.
