MANILA, Philippines — Secretary of State Marco Rubio used a series of high-level meetings in the Philippines this week to announce more than $2.5 billion in new U.S. strategic investments across Southeast Asia, unveil new security, technology and infrastructure initiatives, and reaffirm Washington’s commitment to its alliance with the Philippines and its broader partnership with ASEAN.
Rubio’s July 21-23 visit to Manila comes as the United States seeks to deepen its presence across the Indo-Pacific amid growing geopolitical competition and expanding economic and security challenges in the region.
The State Department said the investments are aimed at strengthening security cooperation, expanding strategic infrastructure, advancing technology partnerships, improving energy security, combating transnational crime and creating new commercial opportunities for American businesses.
Among the largest announcements is a new U.S.-ASEAN AI SPARK initiative under the broader Pax Silica program.
According to the State Department, AI SPARK will support American artificial intelligence exports to Southeast Asia by providing financial and technical assistance to governments interested in deploying American AI technology for public-sector applications.
The United States also announced plans to provide $10 million to strengthen and modernize the Philippines’ critical information and communications technology infrastructure.
Energy security formed another major component of Rubio’s visit.
The Millennium Challenge Corporation approved a $60 million Threshold Program grant for the Philippines designed to enable energy sector investment, strengthen institutions and expand opportunities for American commercial engagement.
Additional funding includes $17 million for the Mekong Minerals Partnership to strengthen critical mineral supply chains and $5 million through the Japan-U.S.-Mekong Power Partnership to promote regional electricity markets, LNG development, U.S. grid technologies and cross-border energy cooperation across Cambodia, Laos, Thailand and Vietnam.
Washington also announced plans to provide $4 million to support mining investment opportunities in the Philippines.
The single largest investment announced during the visit is a $1.5 billion platform through the U.S. International Development Finance Corporation to facilitate energy security infrastructure throughout the Indo-Pacific.
According to the State Department, the investment represents the largest project investment in the Development Finance Corporation’s history.
The United States also announced plans to work with Congress to provide more than $100 million in strategic infrastructure assistance centered on Subic Bay within the Luzon Economic Corridor.
The funding will support upgrades to port facilities and construction of a fuel storage terminal capable of holding more than 120 million liters.
Law enforcement and regional security also featured prominently throughout Rubio’s meetings.
The United States announced plans to provide $2.5 million to help ASEAN countries combat transnational scams, cybercrime, narcotics trafficking and money laundering.
Another $9 million will expand a Philippine Coast Guard pier in Palawan to strengthen maritime law enforcement operations in the South China Sea.
Commercial cooperation also remained a major focus.
The State Department welcomed Philippine Airlines’ announced intent to purchase up to 20 Boeing 787 aircraft powered by GE Aerospace GEnx engines, describing the agreement as evidence of expanding commercial ties between the United States and the Philippines.
According to the department, U.S. companies generated more than $14 billion in commercial agreements across ASEAN during the past year, supporting the potential creation of more than 40,000 American jobs in sectors including aerospace, technology, transportation, energy and health care.
Defense cooperation received significant attention during the visit.
The United States announced $100 million in Foreign Military Financing for the Philippines during fiscal year 2026, representing a $60 million increase over previous annual funding levels.
Another $21.45 million will support International Military Education and Training programs throughout ASEAN, including a new program in Brunei and the resumption of training assistance in Cambodia.
Washington also announced plans to provide $19 million for Philippine counterterrorism programs supporting investigations, prosecutions, information sharing and specialized training.
The United States additionally announced a $6.5 million contract providing the Philippines access to the Rhombus AI Concierge platform for national security analytics, along with $3 million in cyber-related training assistance.
More than $130 million will also continue demining and unexploded ordnance removal efforts in Cambodia, Laos and Vietnam.
Public health initiatives were also announced.
The United States and the Philippines signed a five-year Strategic Objective Agreement containing a jointly funded plan of up to $685 million to improve HIV and tuberculosis prevention, treatment and detection while strengthening global health security.
Rubio later met with Philippine President Ferdinand Marcos Jr. at Malacañan Palace, where both leaders reaffirmed the U.S.-Philippine alliance and discussed regional security, infrastructure development and economic cooperation.
According to the State Department, both sides reaffirmed their commitment to freedom of navigation and overflight in the South China Sea and referenced the tenth anniversary of the 2016 South China Sea arbitral ruling, noting there is no legal basis for China’s expansive maritime claims.
The two leaders also discussed infrastructure projects under the Luzon Economic Corridor, including the State Department’s commitment to work with Congress on more than $100 million in new assistance for logistics and energy projects in Subic.
Rubio and Marcos also discussed opportunities connected to the Philippines’ participation in the Pax Silica initiative and the country’s plans to host the program’s first Economic Security Zone in Clark.
The secretary also highlighted deployment of the Expeditionary Cutter Squadron, which will operate from forward locations in Singapore and the Philippines to support maritime interoperability and regional security.
Rubio also met separately with South Korean Foreign Minister Cho Hyun and Japanese Foreign Minister Motegi Toshimitsu on the sidelines of the ASEAN Foreign Ministers Meetings.
According to the State Department, the three officials emphasized strengthening defense cooperation, maritime security, cybersecurity, energy security and regional stability while expanding efforts against transnational criminal organizations operating scam centers throughout Southeast Asia.
The ministers also reaffirmed support for complete denuclearization of North Korea, continued coordination against North Korean cyber activity and illicit financing, peace and stability across the Taiwan Strait, and expressed concern regarding China’s recent intercontinental ballistic missile launch into the Pacific Ocean.
The officials additionally discussed implementation of their trilateral Memorandum of Cooperation on Small Modular Reactor deployments and efforts to diversify critical supply chains while expanding trusted technology cooperation.
Rubio also met with Indian External Affairs Minister Subrahmanyam Jaishankar.
According to the State Department, the two officials discussed developments in the Middle East and the Indo-Pacific, reviewed progress toward finalizing defense agreements stemming from commitments made by President Donald Trump and Prime Minister Narendra Modi, and said work continues on an interim trade agreement that is nearly complete.
Rubio also joined Australia, India and Japan in issuing a joint statement reaffirming support for ASEAN centrality and unity while emphasizing cooperation on maritime security, economic security, emerging technologies, humanitarian assistance and regional stability throughout the Indo-Pacific.
Before meeting Marcos, Rubio praised the Philippines’ hosting of the ASEAN meetings.
“Well, thank you for welcoming me, first of all, and to congratulate you on the great job hosting this conference, which, in addition to being so critically important for the region, provides us the opportunity to interact with so many countries.”
Rubio also emphasized the longstanding relationship between Washington and Manila.
“And this is a country that has deep ties to the United States in many ways and it’s a partnership that is only growing, and in light of recent events, it’s become more important than ever.”
During remarks at the ASEAN Post-Ministerial Conference with the United States, Rubio reaffirmed American support for the regional organization.
“As President Trump stated last year at the leaders meeting, the U.S.-ASEAN, at the summit, we’re with ASEAN 100 percent.”
Rubio also addressed tensions involving Iran and maritime security.
“The United States is always committed to diplomacy. We are open-minded and always willing to engage in negotiated settlements of differences.”
He added that the United States remains willing to negotiate if commitments are honored.
“If they’re serious, we’re serious. If they’re not, then we will do what is necessary to protect that, our interests, and also the interests of our allies.”
Rubio argued that freedom of navigation through the Strait of Hormuz carries implications far beyond the Middle East.
“So what is at stake here is not simply the issue of what’s happening in the Straits of Hormuz. It’s a very fundamental principle about freedom of navigation.”
Rubio also underscored the strategic importance of Southeast Asia to U.S. national interests.
“This is not charity. This is not something we’re doing because we’re nice people – although I believe we are nice people, but it’s in our national interest.”
He concluded by describing Southeast Asia as central to the future global economy.
“As this region becomes the engine of economic growth in the 21st century – and I’ve said this with all due respect to other parts of the world that we also care about and are involved in – but I believe very much that the future and the story of the 21st century will be written in this region and by how events unfold here.”
