India has decided to join Norway in the World Trade Organisation (WTO) case against the US government decision to impose import duties on steel and aluminium. The Indian government said that their exports will hit by imposing an import tariff on steel and aluminium. India and Norway have joined hands in the larger interests of business. The US government had levied a 25 per cent import duty on steel and 10 per cent on aluminium. India is the tenth largest exporter of steel to the US.
