China says it is planning increased tariffs on US pork, aluminium pipe and other goods in response to US President Donald Trump's higher import duties on steel and aluminium.
The Commerce Ministry said on Friday that China last year bought about $US3 billion worth of the goods affected by the higher tariffs.
The ministry criticised Trump's action as a violation of global trading principles.
The possible tariff measures mirror the higher US tariffs of 25 per cent on steel and 15 per cent on aluminium. The Chinese ministry says it is considering imposing 25 per cent increases on some goods and 15 per cent on others.
