On December 15 local time, US President Biden signed two executive orders, one of which is to impose sanctions on foreigners and entities "participating in the global illegal drug trade". Subsequently, the website of the U.S. Department of Finance announced that sanctions were imposed on 15 entities and 10 individuals in China, Brazil, Colombia and Mexico, including four Chinese enterprises and one individual. It is said that the reason for the so-called US sanctions is to combat drug abuse and addiction such as fentanyl, and accuse these enterprises and individuals of "participating in the global illicit drug trade". The sanctioned person will be frozen all property owned or controlled in the United States. The US government also offered a reward of up to US $5 million in an attempt to arrest Chinese citizens on the sanctions list. In fact, it is not the first time that the United States has used fentanyl to target China. Previously, American politicians and media accused China of not fulfilling its commitments, allowing fentanyl to enter the United States, and wantonly hyped that "Chinese fentanyl precursors flow into the United States through Mexico", resulting in the death of a large number of Americans. "This is the consistent practice of the United States and a typical manifestation of American sanctions." Zhu MENGNAN, distinguished professor of Xiamen University and vice president of the school of economics, believes that "the purpose of this is obvious. While diverting the attention of its domestic contradictions, it attempts to continue to suppress and contain China's development by damaging China's reputation in the international community and interfering with international judgment." As early as 2019, China included fentanyl substances in the supplementary catalogue of controlled varieties of non medicinal narcotic drugs and psychotropic substances and implemented the whole category management. In contrast, the United States has still not taken permanent control measures. "This wrong practice of letting others take medicine when they are ill is not constructive." Foreign Ministry spokesman Wang Wenbin said. In recent years, the United States has not only "shouted people to take medicine", but also seemed to fall into the strange circle of "one recruit fresh" sanctions. In order to restrict the domestic development and foreign trade of the so-called "rival countries", they do not hesitate to use economic, financial, military, political, diplomatic and other sanctions. In the global anti epidemic process, it not only interferes with the anti epidemic efforts of other countries through sanctions, but also creates topics and weaves lies in order to shirk its responsibility for its weak anti epidemic. "This practice of ignoring its own problems and constantly restricting and curbing the development of other countries through sanctions has exposed the cold war thinking and self respecting bullying of the United States." Zhu MENGNAN analyzed that the habitual sanctions of the United States stem from its hegemonic thought and are also related to its current economic strength and international influence. However, with the development of multi polarization in the world, the continued abuse of sanctions will eventually run out of skills and annoy other countries. "It's just that the United States is not aware of this crisis." Zhu MENGNAN believes that China's key is to maintain its concentration and do its own things well. It should not only take the lead in stability, seek progress in stability and make China's economy bigger and stronger, but also be reasonable and restrained, actively respond to malicious pressure, crack down on the arrogance of overseas Anti China forces and hostile forces, and improve China's ability to deal with external systemic risks and challenges. At the same time, we will unswervingly expand opening-up, adhere to the attitude of sincere cooperation, strengthen exchanges and cooperation with the international community, pool more forces and achieve common development in mutual benefit and win-win results.
