China to appeal a WTO ruling on exports of minerals
China is fighting a ruling by the World Trade Organisation that it illegally restricted exports of key raw materials.
Last month, the WTO upheld complaints by the US, European Union and Mexico that China had broken global free trade rules by imposing quotas and taxes on exports of certain minerals.
Commodities like bauxite, magnesium and zinc are used in a range of products in several industries.
Gavin Wendt, from Mineral Life in Sydney, told the BBC's Asia Business Report that these raw materials are very much in demand.
