On May 26, U.S. President Joe Biden ordered a 90-day U.S. intelligence-community investigation into the origins of the coronavirus. On August 27, an unclassified version of the investigation's classified report was released by the Office of the Director of National Intelligence.

Although it is unclear if Biden is satisfied with result, the Chinese Embassy in the U.S. has clearly expressed its firm opposition and strong condemnation, as it offers no constructive and credible insights to the whole world which is still desperately suffering from the pandemic.

On the one hand, the investigation is inconclusive but malicious.

It is not a surprise that the investigation did not fix out the virus origins, because U.S. Director of National Intelligence Avril Haines did hint such inconclusive outcome as early as June 30.

The report did not rule out either natural exposure theory or laboratory leak theory, and it "cunningly" made a claim that "China continues to hinder the global investigation, resist sharing information and blame other countries".

In other words, the U.S. viciously implied that no conclusion was reached mainly because of China's non-cooperation. The White House just repeatedly urged its like-minded partners to exert pressure on China.

On the other hand, the investigation is unilateral and biased.

Shall one believe a report fabricated by the U.S. intelligence community unilaterally? People may not, because the origins tracing should be left to neutral scientists. Although the U.S. has long touted itself as a "global policeman", it only had some infamous track records such as the recent frenzied evacuation from Afghanistan.

It is an open secret that the U.S. holds a moral stand only when its fundamental interests are not affected. Therefore, it is reasonable to question the U.S.' real intention of pushing the coronavirus origin-tracing. It may be a case of "A Thief Posing as Judge".

So far, the U.S. has reported more than 37 million COVID-19 cases with more than 637,000 deaths, the highest in the world. Meanwhile, more emerging clues point to a possibility that the coronavirus may come from the United States. If Biden really cares about the virus origins, he should abandon double standards and proactively probe the labs in his own nation.

The U.S. intelligence investigation stated that the coronavirus wasn't weaponized and unlikely to have been engineered. One should not buy such conclusion lightly until the relevant labs in the world are fully investigated by independent experts from the international community.

The Chinese envoy to the UN Office at Geneva recently sent a joint letter signed by millions of Chinese netizens to the World Health Organization demanding an investigation into the Fort Detrick biological laboratory in the United States. This February, China welcomed the WHO team to make a four-week field-trip to Wuhan to do scientific research, will the U.S. do it, too, in the near future?

Using the coronavirus origin-tracing as a tool, the U.S. is wasting valuable time and energy. Although the U.S.' efforts will likely end up in vain, such blame game will inevitably harm the whole world. The COVID-19 pandemic is still evolving, and global cooperation is needed to overcome the crisis as soon as possible.
