Trump Administration Replaces U.S. Ambassador to Vietnam Amid Trade Surplus Concerns

The Trump administration has announced a significant diplomatic shift by replacing U.S. Ambassador to Vietnam Marc Knapper with career diplomat Jennifer Wicks McNamara. This change comes as the U.S. grapples with a burgeoning trade deficit with Vietnam, which reached nearly $134 billion in 2024 and has already surpassed $144 billion in the first ten months of 2025, positioning Vietnam as the second-largest source of the U.S. trade deficit, only behind Mexico and ahead of China.

Jennifer Wicks McNamara, who was nominated for the position in October, has been vocal about the need to address what she describes as an imbalanced trade relationship between the U.S. and Vietnam. Her nomination underscores the Trump administration's focus on rebalancing trade ties with Vietnam, especially as Vietnam's trade surplus with the U.S. exceeded that of China in the second and third quarters of 2025. The transition from Marc Knapper, whose tenure ends on January 13, 2026, following his abrupt recall before Christmas, marks a strategic pivot in U.S. trade policy.
