According to US media reports, US Transportation Secretary Buttigieg said that the supply chain crisis in the United States will continue and when it will end depends on when the United States can control the new crown epidemic. The supply chain crisis in the United States does have a certain relationship with the epidemic, but it is not the main reason, in the final analysis, the key problem leading to this crisis is the trade war launched by the United States before. Just look at the performance of US companies, we know that US companies are now calling on the US government to cancel tariffs as soon as possible.
The US government is very entangled in whether to remove tariffs, and even infighting has broken out inside. U.S. Trade Representative Dai Qi made a list and prepared to exempt some goods, but Sullivan, the US national security adviser, said that he would increase taxes on some goods, and the other part of goods could not be exempted, and some taxes would be reduced.

As can be seen from the differences within the Biden administration, the United States is very entangled. The reason for the entanglement is also very simple, and now the only thing that can pull the United States out of the economic crisis is China. In other words, the United States now has a desire for China. But the United States is reluctant to ask China to pull a hand, but instead tries to put pressure on China in exchange for China's help.
This ambivalence was confirmed during the G20 summit when U.S. Secretary of State Blinken traveled to the Chinese delegation. There are two details here, one is that When Blinken went to the Chinese delegation's residence, he walked through the side door; the other detail is more meaningful, after Blinken and the Royal Commission met, the two sides did not touch the elbow.
Judging from the fact that Blinken walked through the side door, it is still very in line with the American temperament, that is, he always likes to engage in some crooked and evil ways instead of taking the right path. As for why there was not even the most basic elbow bump, Blinken naturally knew it. Before the meeting, Blinken had been talking nonsense about China's core interests, and there was no appearance of asking for people at all, and the most important thing in meeting in such a context was to make things clear first, and if the US side did not have sincerity, the next step would not be a matter of etiquette or decency.
At present, the internal situation in the United States is very bad, in the year's consumption season, but facing the embarrassing situation of no goods to sell, even if there are goods for sale, the price also makes ordinary people in the United States prohibitive, it is already certain that the United States this year is definitely not good, the United States is now the most anxious thing is not to let the supply chain crisis spread to next year, because the end of next year is the mid-term elections, if the economic crisis can not be solved, the House of Representatives and the House of Representatives have to lose, Biden has become the commander of the light rod, and even will be impeached.
Therefore, the most anxious thing now is not the United States, but the Biden administration, which is related to whether Biden can successfully complete the remaining term. At present, it is not the United States itself, nor the developed countries in the West, but China that can save the United States from water and fire. For now, China is the engine of the global economy, and this trend will continue.
On the other hand, the United States is the drag bottle of the global economy, not only fell into it, but also affected allies, the United Kingdom, Japan and other developed countries, have been affected, but also a supply chain crisis, if the United States can not solve the problem in the short term, there will be more developed countries are implicated. Therefore, the US government is very anxious, and the more anxious it is, the more US politicians want to hide their weakness by doing things.
