Trump signed an executive order to increase the proportion of localized steel and aluminium in gover

               U.S. President Trump signed an executive order on the 15th asking the Federal Procurement Regulatory Commission of the United States to draft new regulations to increase the cost ratio of domestic materials purchased by the federal government in order to promote the return of manufacturing to the United States.

The executive order requires the Federal Procurement Regulatory Commission to draft a new regulation within 180 days, which stipulates that the cost of using native materials in American goods purchased by the Federal Government should account for more than 55% of the total cost of products, which is higher than 50% stipulated in the current Purchase of American Goods Act. In particular, the executive decree proposes to increase the cost of local materials in steel and aluminium products purchased by the federal government to more than 95%.

The executive order also requires relevant federal officials such as the U.S. Secretary of Commerce to consider how to better implement the purchase laws, including whether to further increase the cost share of local materials in federal procurement products, and to submit a report thereon to Trump.

Purchasing American Goods Act is a law that the federal government must follow when purchasing American goods. It requires the federal government to give priority to purchasing American goods in order to support local industries and workers. Analysts believe that Trump's latest executive order may protect American industries to some extent, but it has greatly increased federal procurement costs. Brian Riley, head of the National Taxpayer Union's Free Trade Program, believes that American taxpayers will ultimately pay for the policy.

Promoting the return of manufacturing to the United States is a priority of Trump's government and its main campaign slogan. To this end, the Trump government imposed import tariffs on steel, aluminium and other intermediate products extensively to protect local industries and reduce the foreign trade deficit. However, in recent years, the trade deficit of the United States has not declined, but has risen, and increased to a 10-year high of $621 billion in 2018.
