Jamieson Greer, the recently appointed U.S. Trade Representative under President Donald Trump, has taken bold steps in reshaping America’s trade policy to prioritize domestic production and address foreign trade imbalances. Since his confirmation by the Senate in late February 2025, Greer has been a central figure in implementing the administration’s protectionist agenda, marked by a significant expansion in tariffs and trade policy initiatives targeting unfair practices.
One of Greer’s first major actions was overseeing the release of the 2025 National Trade Estimate Report, which outlined foreign trade barriers impacting U.S. exports, investments, and e-commerce across 59 markets. The report has historically served as a foundation for addressing trade challenges, but the Trump administration is seeking to accelerate progress. President Trump tasked Greer with leading efforts to investigate and counteract harmful trade practices through reciprocal tariffs. Beginning April 5, 2025, a baseline 10% tariff will apply to imports from most countries, a move designed to compel foreign partners to reduce their barriers to U.S. goods and services while supporting domestic industries.
In late March, Greer engaged in high-profile discussions with Vice Premier He Lifeng of China. These talks centered on the economic and trade relationship between the two nations, with Greer emphasizing the need for fair competition and addressing China’s anticompetitive policies. While there were no immediate breakthroughs, both sides recognized the importance of maintaining communication amidst trade tensions. Greer also participated in public hearings focusing on Section 301 investigations into China’s practices in key sectors like semiconductors and shipbuilding, which are seen as critical to U.S. national security and economic interests.
Greer’s approach is deeply influenced by his experience as chief of staff to former USTR Robert Lighthizer during Trump’s first term. He was instrumental in shaping the United States-Mexico-Canada Agreement (USMCA), a trade deal that replaced NAFTA and emphasized protections for American workers. Building on this experience, Greer has promised to open new markets for U.S. goods, tackle the trade deficit, and reinforce the nation’s manufacturing base. Recently, he announced plans for a public consultation process to assess the USMCA’s impact, ahead of its mandatory review in 2026.
Domestically, Greer has garnered praise from industry leaders for his commitment to reorienting trade policy. The American Apparel & Footwear Association lauded his veteran expertise and public service, expressing optimism about collaborating on policies that support U.S. workers and businesses.
As the Trump administration implements sweeping reforms, including additional tariffs on imports from allies such as Canada and Mexico, Greer faces criticism as well. Opponents argue that these measures risk economic inflation and could strain relationships with key partners. Nonetheless, the administration believes this strategy will bolster U.S. manufacturing, strengthen national defense, and restore America's role as a leading producer on the global stage. Greer remains at the forefront of efforts to execute this trade agenda, reflecting the administration’s "America First" philosophy.
