Beijing: As US dragged China to WTO on import duties on chicken products, Beijing on Friday said it has given about USD 9 billion worth of tariff reductions ever since it joined the global trade body a decade ago.

Import tariff reductions since the country's World Trade Organization (WTO) accession a decade ago have amounted to 57. 07 billion yuan (USD 9 billion) by the end of October, China's customs authority told a news agency on Friday.

In the first 10 months of this year, tariff reductions under a slew of preferential trade arrangements amounted to 18.51 billion Yuan, the country's General Administration of Customs said.

After China became an official member of the WTO in December 2001, the general level of the country's import tariffs lowered 15.3 percent to 9.8 percent in 2010.

It has established 16 free trade areas with 29 countries or areas, and carried out 10 free trade agreements and three preferential trade arrangements, the report said.

Meanwhile, US Trade Representative Ron Kirk said in Washington that the US is requesting WTO to establish a dispute settlement panel to address the question of China's imposition of "anti-dumping duties" and "countervailing duties" on imports of chicken "broiler products" from the US.
