China-US trade has been mutually beneficial, and the United States has reaped substantial benefits from the bilateral economic and trade cooperation, China's Ministry of Commerce said Thursday in a research report.

"China-US economic and trade cooperation has reached unprecedented depth and breadth," said the report, noting that bilateral goods trade surged by roughly 252 times from 2.5 billion US dollars in 1979 to 633.5 billion dollars last year.

Bilateral trade in services exceeded 125 billion dollars in 2018, and two-way direct investment totaled nearly 160 billion dollars in the past four decades.

China's surplus came mainly from labor-intensive products, and the country saw deficits for products including aircraft, integrated circuits, automobiles and agricultural products, as well as in service trade, showing both countries have capitalized on their respective industrial advantages, it added.

"Strict control of the United States over exports to China is one of the important reasons for the trade deficit," the report read, adding that US export control measures involve around 3,100 items in 10 categories, including mostly high-tech products.

If the United States liberalizes its export barriers against China to the same level as those applicable to France, the US trade deficit with China would narrow by a third, the report cited the analysis by US Carnegie Endowment for International Peace.

According to the joint study of Chinese and US commerce authorities, the US goods trade deficit data has long been overestimated, with a 21-percent overstatement for 2015, the report said.

Calculated with this percentage, the US side's goods trade deficit of 419.2 billion dollars last year was overstated by 88 billion dollars.

As nearly 53 percent of China's goods trade surplus from the United States came from processing trade, the actual US deficit to China last year should be just 240.9 billion dollars, the report said.

To calculate trade deficit, trade in services should also be taken into account. Counting in cross-border service trade and service sales of affiliated institutions, overall US trade deficit to China should be around 153.6 billion dollars, some 37 percent of US figure for goods trade deficit to China, the report showed.

Although China had trade surplus, the bilateral trade benefits both sides, and the argument of "the United States being taken advantage of" does not hold water, said the report.

China is one of the fastest growing markets for US goods exports, with an average annual growth of 6.3 percent from 2009 to 2018, the report said, adding that the cumulative growth for the period was 73.2 percent, much higher than the average growth of 56.9 percent for other markets of the United States.

The significance of China to the US economy is also reflected in job creation. According to a report released by the US-China Business Council in May 2019, US exports to China supported more than 1.1 million American jobs from 2009 to 2018.

Moreover, 54 percent of China's goods trade surplus from the United States was generated by foreign firms and 53 percent of the surplus came from processing trade. China only earned from limited processing charges while the United States accumulated huge benefits from designing, parts supply and marketing, the report said.

By trading with China, the United States imported a huge amount of high-quality products at low prices, and therefore managed to keep comparatively low inflation rates and reduce its production costs, said the report.
