     China has recently been faced with serious issues of product safety. In Panama, it is said that medicine made with a poisonous chemical sickened some people. A Chinese company had identified it as

diethylamide glycol ( [化]乙二醇), a low - cost substitute commonly used in automobile antifreeze (防冻剂).

     Some countries have banned Chinese-made toothpaste containing diethylamide glycol. China has now

told companies to discontinue its use, even though it says the toothpaste is safe. Another industrial

chemical, melamine, was found in wheat flour used to make pet food in North America. Thousands of

dogs and cats became sick.

     The United States has restricted some imports of Chinese seafood because they contained banned

substance. And questions have been raised about other products, including children's toys covered with

lead paint.

     Chinese officials promised to provide the European Union, the biggest trading partner, with detailed

reports on enforcement efforts against unsafe goods.

     Meglena Kuneva, commissioner (理事) for consumer protection of the European Union said China

should have kept its promise.

     China recently closed three companies linked to the Panama and the pet food scare. And it dismissed

the former head of its food and drug administration. He was found guilty of corruption (腐败) for

approving unsafe drugs. This week, a conference of the State Council approved a proposed special

measure on the supervision of food safety. The Xinhua News Agency said it calls for stronger controls

over producers, greater responsibilities for government and more serious punishment for illegal activities.

     But Chinese officials have accused some foreign media of overstating problems with goods made in

China. They say food imports from the United States also fail inspection sometimes. Next Week,

American and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss

cooperation.
