The direct investment from USA to China has increased from 12.08 billion USD in 2001 to 116.2 billion USD in 2019.
According to the U.S. Bureau of Economic Analysis (BEA), net U.S. FDI flows to China in 2019 were $7.5 billion (up 20% from 2018). Net FDI flows from China into the United States were $4.3 billion (up 168% from 2018, but down from the $18.0 billion level registered in 2016). Additionally, the stock of U.S. FDI in China was $116.2 billion (up 6% from 2018), while China’s FDI stock in the United States was $59.0 billion (up 6%).
Also, China climbed to the No.1 ranking globally attracting foreign direct investment (FDI) of $163 billion in 2020 amid a raging global pandemic, according to the UN's latest report on global investment, knocking the US, which attracted $134 billion.
The dominance of China on FDI cannot be ignored and it is not easy for the Quad to compete with China and its investment strategies.
