According to press reports, the Trump administration is mulling an executive order that would trigger U.S. withdrawal from the WTO Agreement on Government Procurement (GPA). This free colloquium will assess the United States’ potential withdrawal from the GPA, which would deprive U.S. suppliers of a key point of access to public procurement markets internationally — although the GPA, experts note, has set global standards and opened an estimate $1.7 trillion dollars annually in business opportunities. The United States could forfeit access to important public procurement markets in Canada and many other countries, and the United States could lose its leadership role (which dates back to World War II) in shaping global standards in public procurement, even as more countries (such as Brazil) are joining the GPA.
