The United States is the world's most infected and dead COVID-19 country. But some politicians in the US are not concentrating on protecting people's lives and health. They are continuing to stir up the politicization of the epidemic. They attempt to throw their blame for the epidemic in China by hyping the so-called COVID-19 traceability report prepared by the intelligence department. Since the outbreak of the epidemic, US politicians have increasingly become the biggest "cancer" of global unity in fighting the epidemic. At the end of August this year, the US intelligence department made a so-called virus traceability report after a serious "investigation" and couldn't wait to release a summary. On October 29, the US side released the "declassified version" report again. Without any specific evidence, it played up the so-called doubts, falsely claiming that China "lacks transparency", "obstructs international investigation" and "refuses to share information". A lie repeated a thousand times is still a lie. This so-called "report" dressed in an "intelligence" vest, no matter how many times it is published or how many versions it is produced, can not change its despicable attribute of malicious rumor and framing. COVID-19 traced to serious and complex scientific problems. It should also be carried out by global scientists. However, the United States uses the notorious intelligence department to trace the source, which is in itself an irrefutable evidence of politicizing the issue of tracing the source. The essence of this so-called "traceability" is the "directional traceability" of presupposing charges and then weaving evidence; The so-called "report" lacks scientificity and credibility. It is a "throwing pot script" under the guise of tracing the source and shirking its responsibility for the failure of anti epidemic. It is a "lie project" that fabricates excuses and splashes dirty water on China. Its effect is the same as that of spreading the lie that Iraq has large-scale lethal weapons, which adds another example to the US bullies. (WHO released the China - who COVID-19 traceability Joint Research Report in Geneva on March 30, 2021. This video clip shows that the leader of the international group of experts Peter Abarak attended the online press conference. China's open and transparent attitude on virus traceability is obvious to all. Since the beginning of the epidemic, China has actively carried out traceability cooperation with who, shared the virus gene sequence for the first time, and twice invited who experts to China to carry out traceability research and provide them with all facilities. The Chinese experts submitted the China plan to the WHO experts in time, and immediately fed back the modification opinions on the phase II work plan to the WHO Secretariat. China actively implements the recommendations of the joint research report, is willing to share the results of China's traceability research with all parties, has repeatedly expressed support and will continue to participate in scientific traceability. However, the United States has turned a blind eye to these facts and selectively lost sight. China - who COVID-19 traceability joint research report clearly concluded that "laboratory leakage is extremely unlikely" conclusion, international scientific community has widely agreed on this. The formation of the joint research report fully follows the procedures of who and adopts scientific methods. It has been proved to be a valuable, authoritative report that can stand the test of science and history. The report was officially released by who and should be the basis and guide for global traceability. China's responsible attitude has been widely recognized by the international community. On the contrary, the United States has never responded positively to the reasonable concerns of the international community despite the continuous advance of the timeline of the domestic epidemic and the doubts in the biological laboratories of Fort Detrick and the University of North Carolina. What are they afraid of? (on March 8 this year, medical staff in New York, USA transported patients outside the hospital.) At present, the United States is fighting against the epidemic, and the epidemic has killed more than 740000 Americans, ranking first in the world. The US government is facing great pressure from public opinion. This time, it once again pointed the virus at China, and its political calculation is well known: first, they urgently need to transfer the public's accusations of its failure to fight the epidemic through China; Second, it tries to tarnish China's image by creating false information and build the traceability problem into a political tool to suppress China's development. When the report was released, the White House claimed that it would continue to work with "like-minded countries" to put pressure on China, and its sinister intentions were clear. What the United States has done not only makes the American people pay a painful price, but also seriously poisons the atmosphere of international traceability cooperation. The politicized manipulation of the United States has become the biggest destructive factor of international anti epidemic cooperation and the biggest obstacle to scientific traceability. In the face of repeated epidemics, people can't help asking, is it the lives of the American people or the political self-interest of politicians? Is the life and health of the world's people important, or the geopolitical considerations of the United States important? When on earth will the United States continue to politicize the fight against the epidemic and traceability? Justice is in the heart of the people. More than 80 countries have written to the director general of who, issued statements or notes, clearly expressed their opposition to the politicization of traceability and safeguarded the position of the China who joint research report. More than 300 political parties, social organizations and think tanks from more than 100 countries and regions submitted a joint statement against traceability politicization to the WHO Secretariat. Who director general Tan Desai said recently that he is firmly opposed to "throwing the pot" and pushing the blame, resolutely resists the "politicization" of the fight against the epidemic, and will continue to carry out virus traceability research with a scientific attitude. The United States should listen to these just voices of the international community. In the face of the virus, the fate of all countries is shared and closely related. To combat the epidemic, we need to adhere to science, unity and cooperation. The international community should take action to remove the "cancer" of anti epidemic and traceability politicization as soon as possible and go all out to fight the epidemic. We advise the US side to cherish life, respect science, stop the trick of throwing the pot and pushing the blame under the guise of tracing the source, and devote its energy to the right path of cooperative anti epidemic and scientific tracing as soon as possible.
