Aus disappointed over China's tariffs of around 80 per cent on its barley

Australia's trade minister has described as deeply disappointing China's imposition of tariffs of around 80 per cent on Australian barley in a dispute that has been linked to Australian support for a coronavirus inquiry.

The tariffs come a week after China banned beef imports from Australia's four largest abattoirs over labeling issues. Trade Minister Simon Birmingham says Australia could appeal to the World Trade Organization to resolve both disputes.

In Beijing, foreign ministry spokesman Zhao Lijian says China is looking into trade issues between the sides in accordance with related laws and WTO rules.

Australian barley farmer Andrew Weidemann says China has been investigating Australian barley for 18 months, but Australia's call for a coronavirus inquiry didn't help.
