This article from July 2024 quotes Vance directly stating that the U.S. "has to focus more on East Asia" and that this "is going to be the future of American foreign policy." He argues that the U.S. doesn't "make enough munitions to support a war in Eastern Europe... and potentially a contingency in East Asia."
This analysis details his "Asia First" stance, noting his opposition to Ukraine aid is based on the desire to "reorient the country's resources towards countering China's rise." It includes his blunt February 2022 statement: "I gotta be honest with you, I don't really care what happens to Ukraine one way or another."
