This report in WSJ looks at the impact of the 2018 Trump tariffs retained by president Biden as the US seeks to reduce its overdependence on Chinese imports and bring back American manufacturing. This followed misguided policies of previous administrations since Clinton that weakened American manufacturing strengths. Have the US tariffs on Chinese goods worked? The WSJ graph with information from US Census Bureau shows that imports from China in 2022 going down to the levels in 2007 of about 16-17% as a share of US imports, down from a high of 21% before the Trump tariffs halted a rapidly rising curve. Imports from Germany, South Korea and Japan in 2022 were down slightly hovering around 4.5%. Imports increased from Canada and Mexico, the US's traditional partners in North America, around 13.5% as a share of US imports for each country. Also increasing were imports from Vietnam. Some of the imports from Vietnam are Chinese products shipped through Vietnam to evade tariffs, and it is not clear whether the figures from Vietnam have been adjusted for this. President Biden is looking at different scenarios in an effort to tackle inflation. One supported by Janet Yellen, an economist at US Treasury is for the US to relax some of the China tariffs. Most economists in previous administrations including Yellen failed to understand what surrendering American manufacturing to China on the scale and speed that happened would do to communities across America that depended on factory jobs. The devastation of these communities has led to increased divisions in America, weakened American manufacturing, and led to outflow of technologies vital for national security and national well being. Republican senators, US Trade Representative Katherine Tai and National Security Advisor Jake Sullivan are opposed to any relaxation of tariffs. Studies show the removal of the tariffs would have only a small impact on the consumer price inflation index reducing inflation by 0.26%. Lifting some tariffs on school supplies and summer bicycles as proposed by the US Chamber of Commerce would have little or no impact on the consumer price index for inflation. This is because the inflation is triggered by oil and gas price increases stemming from the Russian policies and invasion of Ukraine. This has also aggravated food and grocery costs through blocking of agricultural imports from Ukraine. An additional factor was the increased demand after the pandemic easing in 2022, but that demand is already easing in July with glut in inventories at Walmart and Target, and excess warehouse capacity at Amazon. It would also send the wrong signal to China that the tariffs imposed by president Trump after a Section 301 trade investigation and based on improper loss of technologies to China are not being taken seriously by the US, says Republican Senator Hagerty of Tennessee. The Labor advisory committee to the US Trade Representative Katherine Tai also opposes any such move after the serious damage done to US workers and to US national well being and security. This happened under the Clinton, Bush and Obama administrations with failed trade policies that ceded manufacturing to China. ...
