President Joe Biden told his counterpart Ferdinand Marcos Jr. on Monday that the U.S. commitment to the defense of its ally was "ironclad," including in the South China Sea where Manila is under pressure from China.
Marcos, on the first White House visit by a Philippines leader in 10 years, stressed the importance of the United States as his country's sole treaty ally in a region with "arguably the most complicated geopolitical situation in the world right now."
The two countries reaffirmed their decades-old security alliance in a trip that marks a dramatic turnaround in U.S.-Philippine relations as both countries seek ways to push back against what they see as China's increasingly aggressive actions near Taiwan and in the South China Sea.
U.S. officials said the leaders would agree new guidelines for stronger military cooperation, as well as stepped up economic cooperation.
"The United States remains ironclad in our commitment to the defense of the Philippines, including the South China Sea," Biden told Marcos in the Oval Office.
A joint statement said this meant that any armed attack on Philippine armed forces, public vessels or aircraft in the Pacific, including in the South China Sea, would invoke U.S. mutual defense commitments under a 1951 Mutual Defense Treaty.
Washington sees the Philippines as key to any effort to counter an invasion of Taiwan by China, which claims the self-ruled island as its own territory. Manila recently agreed to allow the United States access to four more of its military bases under an Enhanced Defense Cooperation Agreement, but the two sides have not said what U.S. assets will be stationed at those.
The joint statement said the leaders "affirm the importance of maintaining peace and stability across the Taiwan Strait as an indispensable element of global security and prosperity."
Under Rodrigo Duterte, Marcos' predecessor, U.S. relations soured as he turned the Philippines sharply away from its former colonial ruler and built closer ties with China.
U.S. officials said the new guidelines focused on military coordination across land, sea, air, space and cyberspace, while the U.S. administration would also transfer three C-130 aircraft and look to send additional patrol vessels to the Philippines.
"It is only natural for the Philippines to look to its sole treaty partner in the world to strengthen and to redefine the relationship that we have and the roles that we play in the face of those rising tensions that we see now around the South China, Asia Pacific and Indo-Pacific region," Marcos said.
The summit is the centerpiece of a four-day U.S. visit by Marcos that started on Sunday.
Marcos has sought warm relations with both the United States and China, who are vying for influence in the Indo-Pacific. The Biden-Marcos joint statement did not name the Chinese government.
Experts say Washington considers the Philippines a potential location for rockets, missiles and artillery systems to counter a Chinese amphibious assault on Taiwan.
However, Marcos told reporters on his plane China had agreed to discuss fishing rights in the South China Sea and also that he would not allow the Philippines to become a "staging post" for military action.
TRADE MISSION
The joint statement said Biden would send a Presidential Trade and Investment Mission to the Philippines to enhance investment in clean energy transition, the critical minerals sector, and food security.
The two countries would also co-host in Manila the 2024 Indo-Pacific Business Forum – the marquee U.S. commercial event in the region - which would further establish the Philippines as a key hub for regional supply chains.
The statement also said the countries looked forward to establishing trilateral cooperation with Japan and Australia.
With many Filipinos frustrated by China's actions in the South China Sea, including the harassing of Philippine ships and fishermen in parts that both countries claim, popular support has grown in the Philippines for a tougher stance toward Beijing.
Biden was the first official to reach out to Marcos after his election and has made strengthening economic and military ties in the Indo-Pacific region a cornerstone of his foreign policy.
Before the summit, U.S. lawmakers sent a bipartisan letter to Biden calling on him to raise what they called the worsening human rights "crisis" in the Philippines.
They said there were well-documented violations under Duterte but recent reports showed "ongoing impunity." They cited reports from the Karapatan Human Rights Alliance of 17 extrajudicial killings, 165 illegal arrests from July to December 2022, and a total of 825 political prisoners. A White House summary said human rights were among the topics being discussed by the two countries.
