The practice of selling in foreign markets at less than cost price is known as "dumping". This means that a company is selling its products in another country at a price that is lower than what it would cost to produce them, in order to gain an advantage over competitors in that market. This can be seen as an unfair trade practice because it can harm the local businesses in that country by making it difficult for them to compete. Dumping can also lead to lower quality products being sold, as companies may cut corners to reduce their costs.
