美国和中国贸易关税战暂停的深层原因：美国制造业生产的实物商品，满足不了美国人衣食住行的巨大需求。
贸易关税战起于美国，也必然终止于美国。美国对中国商品加高额关税，中国也对美国商品加高额关税。结果发现，没有中国商品的进口，美国商店缺货了、商品价格上升了。
中国制造业生产了人类生活基本需求的60%以上的物质商品。另一方面，中国是世界150余个国家的最大贸易伙伴，能够提供足够的价廉物美的商品。中国制造惠及全人类。
按美元计价，美国制造业产值约为中国的二分之一。若按实际实物商品产出计算，美国制造业产出和产量，不及中国的五分之一！几乎所有工业产品，包括钢铁、煤炭、水泥、造船、家电、计算机、智能手机等，中国的产量都是美国的几十倍到几百倍。
然而，有意思的是，举个例子，美国的粗钢产量虽然不到中国的十二分之一，但按美元计算，美国钢铁业创造的GDP却比中国钢铁业创造的高一些！这可能吗？！难道物理定律不是普适性的吗？！
The deep reason for the suspension of the US-China trade tariff war: the physical goods produced by the US manufacturing industry cannot meet the huge needs of Americans for food, clothing, housing and transportation.
The trade tariff war started in the United States and will inevitably end in the United States. The United States imposed high tariffs on Chinese goods, and China also imposed high tariffs on American goods. As a result, it was found that without the import of Chinese goods, American stores were out of stock and commodity prices rose.
On the other hand, China's manufacturing industry produces more than 60% of the material goods that meet the basic needs of human life (8 billion people) in the world. China is the largest trading partner of more than 150 countries in the world and can provide enough cheap and good goods. Made in China benefits all mankind.
In terms of US dollars, the output value of US manufacturing is about half of that of China. If calculated by the actual output of physical goods, the output and output of US manufacturing are less than one-fifth of that of China! Almost all industrial products, including steel, coal, cement, shipbuilding, home appliances, computers, smart phones，etc., are produced dozens to hundreds of times by China.
However, it is interesting that, for example, although the crude steel output of the United States is less than one-twelfth of that of China, the GDP created by the US steel industry is higher than that of the Chinese steel industry in terms of US dollars! Is this possible? ! Aren't the laws of physics universal? !
