As the China-US Trade War Is Reignited, Is Your Economy Really At Risk?

Fears of a trade war between the US and China have been escalating after the White House announced on May 29 that it will move forward with its threat to apply a punitive 25% tariff rate on US$50-billion in goods imported from China that “contain industrially significant technology.” The move came on the heels of a joint statement by the US and Chinese trade delegations that had met in Washington, in which both sides agreed to put the punitive trade measures “on hold” and solve bilateral disputes via negotiation.

The capricious attitude of the US administration regarding these trade issues, which might stem from deep-rooted divisions within President Donald Trump’s trade policy team, could intensify a confrontation between the two sides in the near future. This could, in turn, cause one or both sides to launch punitive measures against each other.

We estimate that imposing 25% tariffs on US$50 billion of high-tech content Chinese goods exported to the US will cut the value of American imports of those items by US$11.1 billion

Thus far, China has refrained from announcing new retaliatory measures against the US. At the same time, China’s domestic propaganda continues to claim that it is in China’s own interest to lower import tariffs and further open the domestic market to foreigners. China evidently still prefers to solve the bilateral trade dispute with the US through negotiations.

We attempt to evaluate the impact of the American tariffs on Chinese imports from the perspective of the global value chain. Deepening globalization over the past several decades has formed a complete supply chain centering on China. All actions affecting Chinese exports could thus quickly spill to other economies.

Two-step methodology

Although Chinese enterprises have made important progress in climbing up the global value chain, a considerable proportion of the components of its high-tech exports is still made outside China. For example, China is highly dependent on electronic chips produced in Japan, South Korea, Taiwan and even the US in mobile phones and electronic home appliances.

Because the flow of goods within global production chains is not always reflected in conventional measures of international trade, we used information in the joint OECD–WTO Trade in Value-Added (TiVA) database, which decomposes the value of final goods or services into the value added by each country. TiVA is a statistical approach that estimates the sources (by country and industry) of the value that is added in the production of goods and services for export.

First step: Impact on China

Our approach goes in two steps. First, we estimated to what extent the 25% additional tariff will affect China’s exports by applying the elasticity estimates provided by the World Bank.

On May 20, the US administration unveiled a list of 1,333 Chinese products that it was targeting for tariffs. We expect that the new product list to be released on June 15 will not be much different, since the focus is still on Chinese exports with high-tech content and those related to the “Made in China 2025” program.

We then matched these products to the HS8 categories in the Harmonized Commodity Description and Coding Systems used in international trade, and looked for the corresponding elasticity for each category from the World Bank database.

We estimate that imposing 25% tariffs on US$50 billion of high-tech content Chinese goods exported to the US will cut the value of American imports of those items by US$11.1 billion.
