From the Overview: "The United States and the Republic of the Philippines have maintained a deep relationship that includes a bilateral security alliance, extensive military cooperation, close people-to-people ties, and many shared strategic and economic interests. U.S. past administration of the Philippines as a colonial territory (1898-1946) also has shaped the relationship, by both forging bonds, on the one hand, and, among some Filipinos, creating a wariness of drawing too close to the United States, on the other. Filipino-Americans constitute the third-largest Asian-American group in the United States, numbering over 4.2 million people, and comprise the most numerous foreign-born group in the U.S. Armed Forces. [...] The Philippines has long played an important role in U.S. Asia policy, and it figures prominently in the Biden Administration's Indo-Pacific strategy as one of five regional treaty allies with which the United States has a deepening relationship. The Philippines has been a treaty ally since 1951 and a major non-NATO ally since 2003. It is the largest recipient of U.S. military assistance, equipment, and training in the region."
