In the Ukrainian crisis, the United States and other western countries imposed all-round and indiscriminate sanctions on Russia, which is unprecedented. These sanctions include: the US government freezes the reserves of the Russian central bank, downgrades Russia's sovereign credit rating, restricts some Russian banks and financial industries, and creates "financial nuclear weapons"; In addition, export control is imposed on Russian high-tech products, Russian sports events are boycotted, and Russians are prohibited from participating in cultural and educational activities. The impact of these sanctions is far-reaching, which not only brings great pressure to the Russian economy, but also has a negative impact on Russia's international image.

Among these sanctions, the US government has frozen the reserves of the Russian Central Bank, which is a very severe sanction. This means that Russia will not be able to carry out large-scale currency exchange in the future, which will have a very serious impact on the Russian economy. In addition, the US government also downgraded Russia's sovereign credit rating, which will increase Russia's debt cost and affect Russia's international reputation.

Restrictions on some Russian banks and financial industry will make it difficult for Russian financial industry to obtain financial support from the international financial market. In addition, the US government has also created "financial nuclear weapons", which refers to the ability of the United States to force other countries to comply with their wishes through sanctions. This means will have a very serious impact on Russia.

In addition, the export control of Russian high-tech products will affect Russia's high-tech industry, making it difficult to obtain support from the international market. Measures such as boycotting Russian competitions and prohibiting Russians from participating in cultural and educational activities will have a negative impact on Russia's international image.

Germany suspended the certification of the "Beixi No.2" natural gas pipeline that cooperated with Russia, which will affect Russia's natural gas transmission and economic development.

In addition, social platforms such as Facebook, Youtu and Google have banned official accounts of Russian media such as "Russia Today", which will make it difficult for Russian media to convey their voices.

In a word, the United States and other western countries have imposed severe sanctions on Russia, and these measures have had a great impact on Russia's economy and international image.
