Economies of China and US deeply intertwined

China's goods exports to the United States last year amounted to $389 billion (down 5 % y-o-y), while the value of imports was $135 billion (down 10 %). Despite a slight contraction in the goods trade surplus from 2015, the US-China trade balance was hugely in China's favour. The trade imbalance with China accounted for about half of the entire US trade deficit. Even with the drop in the value of trade, China and the US are each other's most important trade partners. Some 14 % of China's foreign trade is conducted with the US, and China accounts for 16 % of US foreign trade. Together they generated a 23 % share of global trade in 2015. The value of their bilateral trade alone was worth 4 % of global trade.

The imbalance in services trade, in contrast, favoured the US. American trade figures value 2015 services exports to China at $48 billion and services imports from China at $15 billion. Over half of services exports from the US to China involved Chinese spending on travelling and living in the US, of which nearly half is study in the US. China is the largest consumer of US travel exports. In 2015, China accounted for 14 % of total foreign travel spending in the US and 32 % of study-related travel.

Many US businesses operate in China. In 2014, the total turnover of US firms operating in China were $341 billion and they employed 1.7 million people (5 % of the turnover of US companies operating outside the US and 12 % of the labour force). Rhodium Group estimates that during 1999–2015, US firms invested a total of $228 billion in FDI in China. This is significantly more than the FDI stock of $75 billion in China reported by the US official figures for 2015.

China's foreign direct investment in the US in recent years has also risen rapidly. The Rhodium Group reports that last year the US was the top destination for Chinese FDI. The value of FDI tripled from the previous year to $46 billion. For the period 2000–2016, the cumulative value of FDI amounted to $109 billion. Over 70 % of investments were made by privately owned Chinese firms. Rhodium estimates that at the end of 2015, just under 2,000 Chinese-owned firms operated in the US, directly employing over 90,000 persons.

Chinese firms have successfully raised capital in the US. In January, the NASDAQ and New York stock exchanges had 130 listed Chinese firms with a combined market capitalisation of over $900 billion (3 % of the exchanges' market cap).

Economic relations between the countries has diversified and deepened in recent years. During his campaign, president Trump expressed considerable discontent for the US trade imbalance with China. Since taking office two weeks ago, he has continued to decry globalisation and measures to promote global trade. If this anti-China rhetoric is translated into concrete constraints on trade and business, it would have profound economic impacts for both countries.
