Philippines.

Philippine foreign policy under President Ferdinand Marcos Jr. is defined by external balancing against China while preserving ASEAN diplomacy and the legal language of non-alignment. Marcos is both head of state and head of government, and the Department of Foreign Affairs is led by Secretary Enrique Manalo; that leadership configuration matters because the presidency now drives the strategic file more directly than under the previous administration, especially on the South China Sea and alliance management [Official Gazette of the Republic of the Philippines](https://www.officialgazette.gov.ph/), [Department of Foreign Affairs, Philippines](https://dfa.gov.ph/). The formal doctrine remains anchored in the 1987 Constitution’s commitment to an “independent foreign policy,” but in practice Manila has moved toward a tighter US alliance, expanded security cooperation with Japan and Australia, and more open resistance to Chinese coercion in its exclusive economic zone [Official Gazette of the Republic of the Philippines](https://www.officialgazette.gov.ph/constitutions/1987-constitution/), [National Security Policy 2023-2028](https://nsc.gov.ph/images/NSSP/National-Security-Policy-2023-2028.pdf).

Its interests pyramid is unusually clear. Survival and territorial integrity sit first: the top operational priority is defending maritime rights in the West Philippine Sea, backed by the 2016 arbitral award under UNCLOS, which Manila continues to invoke as the legal baseline for its claims [Permanent Court of Arbitration](https://pca-cpa.org/en/cases/7/), [Department of Foreign Affairs, Philippines](https://dfa.gov.ph/). Regime and state security are tied to deterrence credibility and alliance assurance, which is why the Enhanced Defense Cooperation Agreement with the United States has been expanded to additional agreed locations and why joint patrols have resumed [U.S. Department of Defense](https://www.defense.gov/News/Releases/Release/Article/3285858/us-and-philippines-announce-four-new-edca-locations/), [Reuters](https://www.reuters.com/world/asia-pacific/us-philippines-launch-joint-air-sea-patrols-south-china-sea-2023-11-21/). Economic interests come next: China remains a major trade partner, but the Philippines is reducing the strategic risk of overdependence by widening investment, infrastructure, and supply-chain ties with the US, Japan, South Korea, Australia, and the EU [World Bank](https://data.worldbank.org/country/philippines), [Philippine Statistics Authority](https://psa.gov.ph/). Status matters too. Manila wants recognition as a frontline maritime law claimant, a credible US ally, and a middle power voice inside ASEAN rather than a spoiler outside it [ASEAN](https://asean.org/), [Center for Strategic and International Studies](https://www.csis.org/).

The alliance map is asymmetrical but widening. The United States is the Philippines’ only treaty ally through the 1951 Mutual Defense Treaty, and recent bilateral statements have made explicit that armed attacks on Philippine armed forces, public vessels, or aircraft in the Pacific, including the South China Sea, would trigger treaty commitments as interpreted by Washington [Avalon Project, Yale Law School](https://avalon.law.yale.edu/20th_century/phil001.asp), [U.S. Department of State](https://www.state.gov/u-s-security-commitments-to-the-philippines/). Japan has become the most important non-treaty strategic partner, supplying coast guard vessels, negotiating reciprocal access arrangements, and funding maritime capacity-building [Ministry of Foreign Affairs of Japan](https://www.mofa.go.jp/), [Japan International Cooperation Agency](https://www.jica.go.jp/english/). Australia has deepened defense cooperation through a status of visiting forces agreement and increasingly regular exercises [Department of Foreign Affairs and Trade, Australia](https://www.dfat.gov.au/geo/philippines), while South Korea has expanded defense-industrial and naval ties [Ministry of Foreign Affairs, Republic of Korea](https://www.mofa.go.kr/eng/index.do). China is the central rival, but not a severed relationship: Manila still keeps diplomatic channels open, pursues trade, and uses protest notes and leader-level messaging in parallel with deterrence signaling [Department of Foreign Affairs, Philippines](https://dfa.gov.ph/), [Ministry of Foreign Affairs of the People’s Republic of China](https://www.fmprc.gov.cn/eng/).

Regionally, the Philippines uses ASEAN as diplomatic cover but not as a ceiling. It is a founding ASEAN member and continues to support ASEAN centrality, the ASEAN Outlook on the Indo-Pacific, and a rules-based South China Sea order, yet it has been more willing than some mainland Southeast Asian states to name Chinese actions directly and internationalize incidents [ASEAN](https://asean.org/), [Department of Foreign Affairs, Philippines](https://dfa.gov.ph/). That is the key divergence from its bloc: while ASEAN consensus often produces diluted language, Manila increasingly supplements ASEAN with minilateral and alliance-based formats, including trilateral cooperation with the US and Japan and a visibly denser exercise schedule with extra-regional partners [The White House](https://www.whitehouse.gov/briefing-room/statements-releases/2024/04/11/joint-vision-statement-from-the-leaders-of-japan-the-philippines-and-the-united-states/), [U.S. Indo-Pacific Command](https://www.pacom.mil/). The break is not rhetorical; it is structural. The Philippines still defends ASEAN centrality in principle, but when ASEAN underperforms on hard security, Manila now routes around it.

At the UN, the Philippines usually aligns with the broad middle position of a US-partnered but formally independent Southeast Asian state: supportive of the UN Charter, sovereignty language, maritime law, and most human-rights and humanitarian resolutions, but selective where domestic security sensitivities or bloc politics intrude [UN Digital Library](https://digitallibrary.un.org/), [UN General Assembly Voting Data](https://www.un.org/en/ga/). Its clearest pattern is issue-based rather than camp-based voting. Manila has used multilateral law aggressively on maritime disputes through UNCLOS and the arbitral award, yet it does not vote as a simple Western proxy across all files [Permanent Court of Arbitration](https://pca-cpa.org/en/cases/7/), [United Nations Convention on the Law of the Sea](https://www.un.org/depts/los/convention_agreements/convention_overview_convention.htm). The analytically useful insight is that the Philippines breaks from both sides: it is more forward-leaning than much of ASEAN on China, but more autonomy-minded than formal US allies
