The Philippines


Overview and Recent Deveopments
The United States and the Republic of the Philippines
maintain a relationship that includes a bilateral security
alliance, extensive military cooperation, close people-to-
people ties, and many shared strategic and economic
interests. The United States administered the Philippines as
a colonial territory (1898-1946) after 300 years of Spanish
rule. There are over 4 million Filipino Americans, and the
U.S. Department of Veterans Affairs operates its only office
outside of the United States in Manila, serving thousands of
veterans of the U.S. Armed Forces.

Situated east of the South China Sea and south of Taiwan,
the Philippines has long played an important role in U.S.
Asia policy as a security and counterterrorism partner. The
1951 Mutual  Defense Treaty (MDT)  requires the two
countries to help defend each other against external armed
attack. Rising tensions between the Philippines and the
People's Republic of China (PRC or China) over maritime
claims in the South China Sea are a potential regional
flashpoint. Trump Administration officials have reaffirmed
the ironclad U.S. commitment to the Philippines,
including by continuing $500 million in Foreign Military
Financing (FMF)  pledged under the Biden Administration
and approving the sale of 20 F-16 fighter jets.

In late July, Philippine President Ferdinand Bongbong
Marcos  Jr. visited the United States, meeting with President
Donald Trump  and the U.S. secretaries of defense and state.
In addition to reaffirming the importance of the alliance, the
two leaders agreed to a trade framework setting tariff rates
on Philippine goods exports to the United States at 19%.
The United States is the Philippines' third-largest trading
partner, after China and Japan, and its largest export
market. During Marcos' visit, the two sides also announced
that the United States would provide over $60 million in
new  foreign assistance to support energy, maritime, and
economic  growth programs. In September 2025, the United
States announced $250 million in foreign assistance to the
Philippines to improve health systems, disease detection
and response, and maternal and child health services.

Congress has provided oversight, policy direction, and
funding to shape the U.S. relationship with the Philippines,
which is located in the first island chain in the Pacific and
could play a key role in a regional conflict. Members of
Congress have sought to shape U.S. policy on human rights
and counterterrorism in the Philippines, as well as security
cooperation related to the South China Sea.

Ph-pp nes Politics
In 2022, Filipinos elected Marcos Jr. as president and Sara
Duterte-Carpio as vice president. Marcos's father,
Ferdinand Marcos  Sr., ruled the country from 1965 to 1986,
including through martial law from 1972 until he was


ousted by the 1986 People Power Revolution. Sara Duterte
is the daughter of former President Rodrigo Duterte (in
office 2016-2022). The Philippine constitution limits both
the president and vice president, who are elected on
separate tickets, to one six-year term. The Philippines held
midterm  elections in May 2025, in which Marcos-aligned
candidates fared poorly compared to pre-election polling.
Prior to the election, the vice president was impeached in
the House of Representatives for corruption and voicing a
threat against the president; on July 25, the Supreme Court
dismissed the proceedings as unconstitutional, citing a lack
of due process. In March 2025, Rodrigo Duterte was
extradited to the International Criminal Court to face
charges of crimes against humanity for his anti-drug war;
he was formally charged in September.

The   U.S.-Phiippines Allance
In 1992-in  the face of vocal Philippine opposition to U.S.
military bases and during a period of relative peace and
stability following the fall of the Soviet Union-the U.S.
military withdrew from the two bases it had operated since
the Philippine-American War (1899-1902). In 1998, the
two countries signed a Visiting Forces Agreement. In 2014,
with increasing tensions in the South China Sea, the U.S.
and Philippine governments signed an Enhanced Defense
Cooperation Agreement  (EDCA),  allowing the rotational
presence of U.S. military forces, aircraft, and ships at
agreed locations in the Philippines. The two countries
agreed to increase the number of Philippine military bases
open to U.S. forces from five to nine in February 2023.

In May 2023, the two allies established new Bilateral
Defense Guidelines, which aim to help modernize
Philippine defense capabilities, deepen interoperability,
enhance bilateral planning and information-sharing, and
combat transnational and nonconventional threats. The
guidelines appear to reinforce treaty obligations, stating that

either party's armed forces-which includes both nations'
