US Defence Secretary Pete Hegseth calls on allies to increase defence spending and strengthen their own capabilities, citing “alarm” over China’s military buildup. Speaking at the Shangri-La Dialogue in Singapore, he argues that deterrence depends not only on US support but also on allies being more capable and self-reliant. Hegseth frames the issue as a collective approach to security, encouraging partner countries to bolster readiness and sustain investments that improve defence effectiveness. The remarks are delivered in the context of ongoing discussions among regional and international defence leaders at the biennial forum. Overall, his message emphasises that stronger allied forces are intended to help prevent destabilising changes in the regional security environment, while maintaining strategic stability. The comments focus on defence spending and preparedness as practical steps allies can take to respond to evolving security challenges, including China’s growing military activity.
