Legal analysis: sanctions can usually be divided into three categories: measures to control the foreign assets of the sanctioned country, including suspending economic sanctions, freezing its state-owned assets and private property, and confiscating state-owned or private property. Take a series of financial and financial sanctions 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. Trade sanctions such as stopping economic assistance and cooperation, suspending economic and trade treaties and agreements, stopping providing most-favored-nation treatment, partially or completely stopping import and export trade, and blocking trade ports are adopted.

Legal basis: Article 3 of People's Republic of China (PRC)'s Anti-Foreign Sanctions Law: People's Republic of China (PRC) opposes hegemonism and power politics, and any country interferes in China's internal affairs under any pretext and in any way. If foreign countries violate international law and the basic norms of international relations, contain and suppress China under various pretexts or according to their own laws, take discriminatory and restrictive measures against China citizens and organizations and interfere in China's internal affairs, China has the right to take corresponding countermeasures.
