TIMELINE-China and Australia commodities trade tensions

Australian shipments of beef, barley and coal worth billions of dollars have been the most impacted by recent measures, and China has been able to find alternative supplies easily.

Australia's ties with top trade partner China soured in 2018 when it became the first country to publicly ban China's Huawei from its 5G network, and worsened after Canberra called for an enquiry into the origins of the coronavirus. Tit-for-tat diplomatic reprisals have since followed, including raids on the homes of Chinese journalists in Australia, evacuation of some Australian journalists from China and a raft of trade measures imposed by China on Australian exports.
