ANTI-DUMPING duties on imported US chicken are to be lowered by China in line with last year's ruling against Beijing by the World Trade Organisation in a four-year-old row.

The Ministry of Commerce on its website China will levy anti-dumping taxes ranging from 46.6 per cent to 73.8 per cent on imports from US suppliers.

It would also levy anti-subsidy taxes ranging from four per cent to 4.2 per cent on US chicken producers.

The anti-dumping and anti-subsidy duties were previously set at a whopping 105.4 per cent and 30.3 per cent, respectively, Reuters reported.

The ministry said a re-investigation found evidence that US chicken exporters dump products in the domestic market and cause substantial harm to local industry.

US exports of chicken to China have fallen 90 per cent since 2010, costing sellers US$1 billion in the wake of the Central Government imposing the high anti-dumping duties.
