Chinese buyers have purchased between 400,000 and 500,000 tonnes of wheat from Australia and Canada due to potential crop damage from heat waves at home. The purchases include milling quality wheat from Australia for delivery in July or August, and about 200,000 tonnes from Canada. This marks the first Australian wheat purchases by China since last year. The article also notes that Chinese importers have booked large volumes of barley, with some estimates putting the volume at 1 million tonnes for delivery this summer.
