Tomato prices in Ho Chi Minh City have soared to 45,000 - 50,000 VND/kg due to hot weather and prolonged drought, making them more expensive than some imported fruits like Australian tangerines. This has led to limited availability in markets and supermarkets, with traders and suppliers struggling to meet demand and even advising customers against purchasing due to high costs. Companies producing tomato-based products are also affected, although those with stored materials are less impacted.
