He demanded that allies spend at least 3.5% of their GDP on defence, warning that "allies who refuse to step up and carry their own weight for our collective defence will face a clear shift in how we do business.""For those nations, we are moving them to the front of the line: expedited arms sales, deep industrial-based collaboration, expanded intelligence sharing," he said.He praised India, Vietnam, the Philippines, Australia, Indonesia, Malaysia and Singapore for stepping up and improving military readiness, while taking aim at Europe."Europe should take note," Hegseth said, adding that "for too long, the security of this region has rested disproportionately on American military power, while many of our allies and partners allowed their own defence capabilities to atrophy."Alliances should happen "without the drama and the moralising," he said.Iran-linked security concerns in the Gulf region and the blockade of the Strait of Hormuz are also key themes of this year's discussions. Many Asian countries are anxious to see the conflict resolved as they depend on fuel and fertiliser imports from the region.What is the Shangri-La Dialogue?Billed as "Asia's premier defence summit," the Shangri-La Dialogue is an annual security conference hosted by the International Institute for Strategic Studies (IISS) in Singapore. It brings together defence ministers, military chiefs, and security officials from across the Asia-Pacific and beyond to discuss regional security challenges, military cooperation, and geopolitical tensions.This year's edition runs from Friday to Sunday. Attendees include Australian Defence Minister Richard Marles, French Armed Forces Minister Catherine Vautrin, and Qatar's Deputy Prime Minister and Minister of State for Defence Affairs Sheikh Saoud bin Abdulrahman bin Hassan Al Thani.Chinese Defence Minister Dong Jun is not attending for the second consecutive year. Beijing has instead sent a delegation of "experts and scholars" from the People's Liberation Army.
