American leaders have made numerous visits to the Philippines, a long-standing military ally in Southeast Asia. But Vice President Kamala Harrisā stop on Tuesday in the countryās archipelagic province of Palawan represents something new. She is the first U.S. official to go there, in what observers say is meant more as a message to China than one to the Philippines.

Harris toured a coast guard vessel and spoke to Philippine officials in Palawan to underscore Americaās values and hopes for the region: ārespect for sovereignty and international integrity, unimpeded lawful commerce, the peaceful resolution of disputes, and freedom of navigation.ā

The Vice Presidentās visit, along with talks in Manila on Monday about increased joint defense projects, leaves the Philippines in a precarious positionāstraddling the line between the interests of its colonizer-turned-ally in the U.S. and its largest trade partner in China. Across the region, countries have been put in a similar tight spot, increasingly forced to choose a side where they might prefer to stay above the fray in the competition for global influence between the U.S. and China.

Ferdinand Marcos Jr., who was elected president of the Philippines in May, said in July that, like many of his regional counterparts, he would pursue āa friend to all, an enemy to noneā foreign policy. But this aim has become more untenable as differences between the worldās two superpowers grow over issues concerning human rights, economic policy, and the rule of law.

Itās no coincidence Harris visited Palawan. Just off its west coast is the South China Sea: a waterway that has become a regional flashpoint after Beijing lay claim to virtually all of it and its encompassing islands, citing historic maps. China is not the only claimantāthe Philippines, Vietnam, Malaysia, and Taiwan have also staked claims to overlapping maritime territories. But China has bolstered its presence in recent years, building artificial islands from the seaās obscure reefs and sandbars and arming them with missile systems. A U.N.-backed tribunal in The Hague, Netherlands, invalidated most of Chinaās sweeping claims in 2016, but Beijing ignores the ruling and continues to militarize the region.

Local tensions in the South China Sea eased some after the Philippines, which lodged the complaint against China to The Hague, under former President Rodrigo Duterte did not enforce the tribunalās ruling. Duterte was keen on pivoting the Philippines away from its deference to the U.S.. As Duterte was reluctant to hold Beijing to account to smooth diplomatic relations, Chinese incursions in the contested waterway increased.
Since Marcos Jr. succeeded Duterte, he has sought to restore the Philippinesā relationship with the U.S., whose military still actively challenges Chinaās claims in the South China Sea. At the same time, Marcos Jr. insists that Harrisā visit will not strain Manila-Beijing ties. āI donāt think it will cause problems,ā he told Philippine reporters last week. But Lucio Pitlo, a research fellow from Manila-based think tank Asia Pacific Pathways to Progress Foundation, says China will definitely be keeping an eye on the visit and will āsurely express serious concern aboutā the U.S.ās increasing military footprint in the country.
Resetting the relationship with the U.S.
Several key treaties over past decades form the bedrock of the partnership between the U.S. and the Philippines. A 1951 Mutual Defense Treaty states that both nations will provide support to each other in the event of an external attack. This has been reaffirmed by a 1998 Visiting Forces Agreement and a 2014 Enhanced Defense Cooperation Agreement, allowing the U.S. military to access bases in the Southeast Asian nation and store defense equipment there. The two militaries also regularly hold joint exercises.
By virtue of its geography, the Philippines has strategic value for the U.S. in its competition with China. Besides having the South China Sea to its west, the major island of Luzonāwhich contains the countryās capital Manilaāis only 360 km south of Taiwan.

Derek Grossman, a senior defense analyst at the global policy think tank RAND Corporation, says the reinvigorated U.S.-Philippines alliance under Philippine leader Ferdinand Marcos Jr. has āreal security implications for China in the South China Sea.ā
Gregory Poling, director of the Southeast Asia Program and Asia Maritime Transparency Initiative at the Washington-based Center for Strategic and International Studies, said the Philippines will find it āvery difficult to stay neutralā if conflict arises in Taiwan and the U.S. becomes involved. Some 150,000 Filipinos residing in Taiwan would be at risk, and the Philippines may ādeal with a refugee crisis along with other externalities,ā he adds.
In a September interview with Japanese outlet Nikkei Asia, the Philippine envoy to the U.S. Jose Manuel Romualdezāa cousin of Marcos Jr.āsaid Manila would let Washington use its bases in the event of a Taiwan conflict, āif itās important for us, for our own security.ā Itās a tonal shift from when Duterte, who wanted to boot U.S. forces out of the archipelago, was in charge. In a 2016 trip to Beijing, Duterte proclaimed that it was ātime to say goodbye to Washington.ā

But while Marcos Jr. has taken a different tack than his predecessor, he is cautious not to alienate China as he pursues revamping ties with Washington. He met with Chinaās Xi Jinping on the sidelines of the Asia-Pacific Economic Cooperation Summit in Bangkok, Thailand, last week shortly before Harrisā visit, promising an improvement of the Manila-Beijing relations.
Marcos wants to avoid a repeat of the past. After a Philippine vessel squared off with Chinese boats within the Philippinesā exclusive economic zone back in 2012, China imposed trade barriers on bananas from the Philippines. Banana exports to China fell by around 27% to 473,000 metric tons in 2012 from 650,000 tons the year prior. The fruit is one of the countryās major agriculture exports, and its growers believed the dispute was to blame for their economic losses.
Treading a fine line with China
Chinaās foreign ministry issued a statement after the meeting in Bangkok last week saying it must work together with the Philippines against ābullyingā in the South China Seaāsomething Beijing and Washington each accuse the other of doing with their military movements in the region. Marcos Jr., for his part, clarified that his foreign policy doctrine has always been to engage with all parties, especially concerning the maritime dispute. āLetās not allow anyone to dictate what we should do,ā he told reporters last week.
In a briefing in Palawan, Harris reiterated Americaās support for the 2016 ruling from The Hague on the South China Sea dispute, adding that the U.S. āwill continue to rally our allies and partners against unlawful and irresponsible behaviorā in the region. Washington also promised to give Manila $7.5 million worth of assistance to its maritime law enforcement agencies.
Beijing has yet to react to Harrisā statement, although its response is expected to be much more muted than the response to Democratic House Speaker Nancy Pelosiās visit to Taiwan in August. The Philippines is not disputed territory. The day before Harrisā trip, Chinaās foreign ministry said it is not against the U.S. interacting with other states in the regionābut it should be for āpeace and stability and not damaging to other countriesā interests.ā

Richard Heydarian, a Manila-based political scientist and senior lecturer of international affairs at the University of the Philippines, says Philippine-China ties wonāt break down over the South China Sea territorial row. But itās Washingtonās increasing military investments on the archipelago that Beijing will be wary of, particularly when it comes to potential future conflict over Taiwan. āBoth the South China Sea and the Taiwan crisis are nudging the United States and Philippines to fortify their alliances,ā he says.
To reap the benefits of amicable relations with both China and the U.S., as the Philippines and many of its counterparts across Southeast Asia seek to do, says Anna Malindog-Uy, a geopolitical analyst at the Asian Century Philippines Strategic Studies Institute in Manila, the Philippines must āprevent at all costs the possibility of becoming a pawn of any superpower to encircle another superpower.ā
