The latest decision followed a review launched a year ago that found the domestic industry could be harmed if anti- dumping duties were discontinued.
The anti-dumping duties were extended for another five years in 2011.
China's Ministry of Commerce (MOC) has further extended anti-dumping duties from tomorrow on chloroprene rubber imported from these countries on the grounds that the products were being dumped on the Chinese market at lower-than-market prices, state-run Xinhua news agency reported.
Chloroprene rubber, commonly known as Neoprene, is mostly used to manufacture electrical cables and waterproof products.
