Economic sanctions refer to economic punishment measures taken by one or more countries against countries that violate international obligations, treaties and agreements. It is often used by countries with strong economic strength as a means to attack and weaken the political, economic and military strength of other countries.

Economic sanctions were originally an auxiliary means of war, aiming at weakening the enemy's combat capability by weakening its economic strength.

Common ways include: implementing trade embargo, interrupting economic cooperation, cutting off economic or technical assistance, etc. However, economic sanctions are also a double-edged sword, and sanctions countries will also suffer certain economic losses. Broadly speaking, sanctions such as arms trade are also economic sanctions. In financial management, economic sanctions refer to economic penalties imposed on units or individuals who violate economic laws and regulations in macroeconomic and microeconomic operations.

Means include:

1. Measures to control the foreign assets of the sanctioned country, including detaining and freezing its state-owned assets and private property, and confiscating state-owned or private property.

Second, a series of financial and financial sanctions have been taken against the sanctioned country, such as stopping providing loans, restricting or stopping foreign exchange, excluding its business activities in the international financial market, and interfering with the operation of its domestic financial market.

3. To stop economic assistance and cooperation, suspend economic and trade treaties and agreements, stop providing most-favored-nation treatment, partially or completely stop import and export trade, and block trade ports. In international relations, economic sanctions can also be used as a means of revenge.
