The future of the global economic order is in flux. Beijing's coercive economic policies, President Trump’s unprecedented tariffs, and the embrace of industrial policies around the world have cast doubt on the future of international economic rules. Globally, countries like Australia are being forced to contend with a more fragmented economic landscape that is affecting trade and technology flows, supply chains, multilateral institutions, and relations with the major powers.

In this era of unpredictability, critical questions arise:

• Where are Trump's tariffs heading and how will they impact US economic relations and the United States as a place to do business?
• Are the US and China heading for economic decoupling?
• How should countries like Australia, Japan, South Korea, and India navigate great power competition and economic pressure?
• What is the impact on alliance relations?
• What role will minilateral and regional groups play in shaping a post-tariff global order?

These questions were discussed by leading expert in diplomacy and economic affairs in East Asia, Ambassador Kurt Tong and USSC CEO, Dr Michael J. Green, at a public event moderated by USSC Director of Economic Security Hayley Channer.

To launch USSC senior lecturer Dr Kathryn Schumaker's new book, Tangled Fortunes: The Hidden History of Interracial Marriage in the Jim Crow South (Basic Books, 2025), Dr Schumaker was joined by scholars Dr Michael Green, Associate Professor Frances Clarke, and Dr Aaron Nyerges to discuss the themes of the book.

Prior to the US Supreme Court’s 1967 ruling in Loving v. Virginia, most American states prohibited interracial marriages at one time or another. But as Dr Schumaker reveals in Tangled Fortunes, such laws did not effectively prevent interracial marriages. Indeed, enforcement of such laws was inconsistent when it came to relationships between white men and Black women. In some Southern communities, such unions were tolerated – though often subject to social disapproval. The book offers a new narrative of the rise and fall of racial segregation from the perspectives of ordinary people whose primary goal was to keep their families together in the face of great difficulty.

Out of sight, out of mind. Low Earth Orbit has undeniably become busier, with upwards of 10,000 satellites and millions of pieces of space debris currently in orbit. With vital services—ranging from communications to climate monitoring, national defence, and financial services—increasingly reliant on space, the proliferation of space assets and debris, and the associated risks of collisions, explosions, and anti-satellite warfare have become a major political issue.

Countries have developed new tools and cultivated norms to improve traffic management and space sustainability. However, amid a proliferation of space stakeholders; the absence of binding international agreements; and challenges in monitoring activities in space, significant gaps remain.

How are public and private actors navigating the challenges of growing congestion in space? How can international frameworks like the Outer Space Treaty be strengthened to address these risks? And how can space sustainability be integrated into the national security policy debate?

To address these questions, the United States Studies Centre was pleased to host a webinar with Audrey M. Schaffer. Ms Schaffer is an internationally recognised expert in space policy, currently serving as Vice President of Strategy and Policy at Slingshot Aerospace and Non-Resident Senior Associate with the Aerospace Security Project at the Center for Strategic and International Studies. She previously served in the US government for over 15 years, holding positions in the Executive Office of the President, Department of Defense, Department of State, and National Aeronautics and Space Administration (NASA). Ms Schaffer led the US delegation that negotiated the UN Guidelines for Space Sustainability and, from 2021–23, served as Director for Space Policy on the National Security Council of the Biden-Harris Administration.

This webinar was hosted by Dr Kathryn Robison, Lecturer in American Studies at the United States Studies Centre and Senior Research Fellow at the Australian Centre for Space Governance.

This event was made possible with funding from the US State Department.
