78 years ago today, on March 14, 1947 (February 22, 1947 lunar calendar), the US-Philippines military base agreement was signed, with a lease term of 99 years. On March 14, 1947, the United States and the Philippines signed an agreement in Manila for the continued use and expansion of US military bases in the Philippines. The term is 99 years. The main content of the agreement is: The United States leases 23 land, sea and air bases in the Philippines, and can add and open new bases as needed. The United States enjoys extensive extraterritorial jurisdiction in the bases. The agreement has been revised many times. The main US military bases in the Philippines are Subic Naval Base and Clark Air Force Base in southern Luzon, which are also the main US bases in the Pacific. In 1979, the two sides revised the agreement, and the Philippines regained sovereignty over the base and appointed a Filipino as the base commander, but the US commander retained control. The agreement is reviewed every five years. After the expiration of the agreement in 1991, if the two sides agree to extend it, the United States will provide the Philippines with five hundred million US dollars in assistance within five years as compensation for the use of the base. In June 1983, the United States and the Philippines signed another agreement. The Philippines agreed to continue to use the Subic Naval Base and Clark Air Force Base from 1984 to 1989, and the United States provided the Philippines with nine hundred million US dollars in economic and military assistance.
