On March 31, U.S. President Donald Trump signed two executive orders to review the reasons why United States has trade deficits with some of its trading partners. The U.S.-China trade deficit is certainly an important topic of the review. Traditionally the U.S. government has been focused on factors on the Chinese side，charging that the RMB is undervalued, policy-making in the Chinese government is not transparent, labor rights and intellectual property rights in China are not fully respected, etc.
The U.S. government always denies that its own policy significantly contributes to the U.S.-China trade deficit. For example, it has repeatedly claimed that the impact of U.S. restrictions on its exports to China is extremely small and can hence be ignored. Its argument is that the value of denied exports compared to that of total U.S. exports to China is tiny, so the U.S. export controls vis-a-vis don’t create its trade deficit.
The problem is that American companies who see no hope to receive licenses from the US government would not apply. So their potential exports discouraged by the licensing system are not included in the statistics of denied exports. The U.S. government does not know the value of potential exports that are abandoned over concerns related to the export-control regime and to political pressures.
Our paper in 2013 proposed a method of comparing U.S. export compositions to different countries, and of estimating how U.S. export barriers against China make the U.S. export composition to China different from that to other countries. The more the United States assumes that a country is a military threat, the less it wants to sell products with military applications to that country. Consequentially, export barriers in the United States change both the total amount and the pattern of U.S. exports to a country. Through a comparison of compositions of U.S. exports to different countries, we can estimate how much potential exports to China are blocked by U.S. political barriers.
U.S. exports are classified as 137 common items and many are dual-use for both military and civilian purposes. The U.S. government has a system to control the export of its items that might be used for military purposes by other countries. Fundamentally, the scope of control varies according to the destination countries. Those viewed by the United States as serious military threats are less likely to receive items with high military applications. As a result, the proportion of items with high military applications among the total exported to these countries is small. By comparing the compositions of U.S. exports to different countries, one can ascertain exactly how serious U.S. export barriers against these countries actually are.
We categorize the aforementioned 137 export items into two groups. The first includes military products and dual-use items with high military applications, and is defined as “exports of items with high military applications”. The second includes items with low military applications, or items that are widely available in the world market. We also define the value proportions of the two groups in total exports as weights of the two groups.
So the weights of the two groups in the total exports can imply the seriousness of U.S. export barriers against a country.
Besides export barriers, three other factors may in principle also change the weights of the two groups. They are: demands of the importer, the competitiveness of products and the productivity of the exporter. However, in our research, these three variables can be well-controlled by carefully selecting countries for comparison. In our analysis, the three economic factors are irrelevant to lowering U.S. exports of items in the first group to China.
To test the sensitivity of our selection of the items in the two groups, we choose three different scopes of items from among the total 137 items, from large to small, for the first group. The data we used for this analysis are from the United States International Trade Commission and they include U.S. exports to different countries during 1989 – 2009.
According to average 2004–2009 data, if the United States were to liberalize its export barriers against China to the same level as those applicable to France, U.S. exports to China would increase by $45.7–$76.0 billion, at a growth rate of 82.71–137.59%, thereby narrowing the U.S.–China trade deficit by 20.28–33.74%. Similarly, should the U.S. adjust its export barriers against China according to those applicable to Brazil, the increment of exports would be $13.5–$54.9 billion, a growth rate of 24.25–99.41%, narrowing the U.S.-China trade deficit by 5.95–24.38%. At India’s level, the increment of exports would be $12.0–$31.5 billion, a growth rate of 21.74–56.94%, narrowing the U.S.-China trade deficit by 5.33–13.96%. And if the United States rolled back its export barriers against China to the 1998 level, its exports to China would increase by $17.8–$37.8 billion, a growth rate of 32.23–68.45%, narrowing the deficit by 7.90–16.79%.
Our analysis shows that a significant amount of U.S. potential exports to China were blocked by its political barriers during 2004-2009. The situation continues today. The Trump Administration needs to understand these realities in its review of trade relations with China.
