WTO members imposed 22 new anti-dumping duties against China in the second half of 2005, a slight decrease on the 25 penalties added during the same period in 2004. But this didn't stop China topping the list of the world's most penalized nations. A total of 15 WTO members claimed they had found evidence of producers exporting goods priced lower than the market price in their home countries and used this as grounds for 76 new penalties worldwide. The EU introduced the most duties, a total of 19, but China started the largest number of anti-dumping investigations into foreign countries' products. Plastics, and iron, steel and aluminum were the most targeted sectors.
