The price of sunflower oil has reached an all-time high due to the ongoing war between Russia and Ukraine, the world's largest suppliers of the oil. The conflict is expected to have a ripple effect on the global agricultural market, with Ukraine being a major exporter of wheat, corn, and sunflower oil, and Russia being a significant supplier of sunflower oil. The increase in sunflower oil prices could directly impact the tuna industry, as it is a key ingredient in tuna processing. The war may also lead to higher tuna prices due to increased fishing costs and shipping rates. This could potentially slow down Vietnam's tuna exports, despite the growth in its tuna exports to Russia and Ukraine.
