反倾销是指进口国主管机构对进口产品采取的一种措施，以防止倾销行为对进口国国内产业造成损害。反倾销是进口国保护本国产业的一种贸易政策，具有很强的保护性。

反倾销的措施包括征收反倾销税、中止进口、取消进口许可证等。其中，征收反倾销税是最常见的措施，它是通过对进口产品征收额外的关税来提高其价格，从而减少其在国内市场上的销售量。中止进口是指进口国禁止某些倾销产品进口的行为。取消进口许可证是指进口国政府取消已经授予的进口许可证，禁止某些倾销产品进口的行为。

反倾销的成立需要满足一定的条件。首先，进口产品存在倾销行为，即以低于正常价值的价格在进口国市场上销售。其次，倾销行为对进口国国内产业造成了损害，包括实质性损害、实质性威胁和实质性阻碍。最后，倾销行为与损害之间存在因果关系。

反倾销的实施过程比较复杂，需要经过一系列的调查和听证等程序。同时，反倾销也存在着一些争议，例如其是否会导致贸易战、是否会影响到国际贸易的正常发展等。

Anti-dumping refers to a measure taken by the competent authorities of the importing country against imported products to prevent the damage caused to domestic industries by dumping. Anti-dumping is a trade policy adopted by the importing country to protect its domestic industry, which has strong protective features.

Anti-dumping measures include imposing anti-dumping duties, suspending imports, and canceling import licenses. Among them, imposing anti-dumping duties is the most common measure, which is to increase the price of imported products by imposing additional tariffs to reduce their sales in the domestic market. Suspending imports refers to the importing country's ban on the import of certain dumped products. Canceling import licenses refers to the importing country's government canceling already granted import licenses, prohibiting the import of certain dumped products.

The establishment of anti-dumping measures requires meeting certain conditions. First, there is dumping behavior by imported products, which is selling at a price lower than the normal value in the importing country's market. Second, there is damage to the domestic industry of the importing country, including material damage, material threat, and material hindrance. Finally, there is a causal relationship between the dumping behavior and the damage.

The implementation process of anti-dumping is relatively complex and requires a series of investigation and hearing procedures. At the same time, anti-dumping also has some disputes, such as whether it will lead to a trade war, whether it will affect the normal development of international trade, etc.
