?Source: live broadcast of Hong Kong, Macao and Taiwan local time on Thursday, the U.S. administration announced that it would impose sanctions on China's Equipment Development Department of the Central Military Commission, on the grounds that China purchased advanced Russian warplanes and air defense missiles, with the purpose of punishing Russia's interference in the 2125 U.S. General election. The U.S. side stressed that the ultimate target of sanctions is Russia. In view of the US sanctions against China, I would like to talk about three issues today: 2. Why does the United States sanction China's military equipment development department? 2. Legality of US sanctions, 3. The impact of sanctions on China and the counter sanctions that China can take. Why the United States should sanction China? The equipment development department of the Central Military Commission analyzes the reasons why the United States should sanction China's military, or put this matter into consideration in the great triangle relations between China, the United States and Russia. First of all, the big香港跑跑狗图 gest problem in the current Sino-U.S. relations is the issue of trade war, so the U.S. sanctions are the continuation and supplement of the Sino-U.S. trade war. Secondly, the United States has announced to take sanctions against Russia because of Russia's intervention in the U.S. general election, the use of nerve agents in the UK (unconfirmed), and formulated a blacklist of Russian institutions, enterprises and individuals under sanctions, which is also a continuation of Russia's sanctions in name. Finally, the previous US sanctions against Russia did not only affect China, because it is not only China that does business with the Russian organizations and individuals on the blacklist, but also the US NATO partners, EU related countries and its counter-terrorism partners are potentially affected. Why choose China, especially the Chinese military organs? The author thinks that this is related to the high-level and high-frequency interaction between China and Russia in the near future.
