Why is Rio Tinto stock sliding today?

Rio Tinto's stock fell 3.2% to A$173.52 due to a contract dispute with China's central iron ore buyer, China Mineral Resources Group. The dispute has led to a pause in purchasing talks for Rio Tinto's flagship iron ore product, impacting investor confidence. Iron ore prices have also been trading below US$100 per tonne, adding to the pressure. The broader Australian mining sector, including BHP, Fortescue, and South32, also saw declines.
