Foreign investment in the United States dropped by about 32 percent last year, according to the US Bureau of Economic Analysis. Down from a high of $439.5 billion in 2015, overseas investors spent only $259.6 billion in 2017 to launch and further businesses in the U.S.
The largest chunk of last year's foreign direct investment came from Canada ($66.2 billion), followed by the United Kingdom and Japan.
The United States wasn't the only country to receive less money from outside its borders last year. According tothe Organization for Economic Cooperation and Development, global foreign direct investment flows were down 18% in 2017 from the previous year and nearly 24% from its post-recession high in 2015, which the OECD attributed to a surge in financial and corporate restructuring.
As for future foreign investment in American companies, the Trump administration could be making such endeavors more difficult.
President Donald Trump has celebrated foreign business activities in the United States, including the Chinese company Foxconn's construction of a factory in Wisconsin. But the White House also blocked Singaporean chipmaker Broadcom's acquisition of California-based Qualcomm, citing concerns that American technology could end up in the hands of China.
Trade adviser Peter Navarro, meanwhile, has characterized foreign investment as "conquest by purchase."
"In the long run, we are likely to be owned by foreigners," he said last year.
