The South China Sea remains a focal point of escalating tensions between the United States and China, with the two superpowers clashing over territorial claims and freedom of navigation operations (FONOPs). Recent U.S. naval maneuvers have drawn strong reactions from Beijing, while reports suggest that China is considering similar operations in the northern Pacific, further fueling concerns over regional security and strategic competition.
U.S. FONOPs Challenge Beijing’s Expanding Claims
In recent months, the United States has intensified its freedom of navigation operations in the South China Sea, challenging China’s extensive maritime claims. On January 18, 2025, the USS Gabrielle Giffords, a Littoral Combat Ship, conducted a FONOP near the contested Spratly Islands. This operation follows a series of similar missions, including one in December 2024, when the USS Benfold navigated near the Paracel Islands. These operations, according to the U.S. Navy, aim to uphold international maritime law as defined by the United Nations Convention on the Law of the Sea (UNCLOS).
China has condemned these actions as provocations, accusing Washington of undermining regional stability. The Chinese Ministry of National Defense released a statement asserting that the People’s Liberation Army (PLA) Navy had “expelled” the USS Gabrielle Giffords from what it calls its “indisputable waters.” However, the U.S. maintains that these waters are part of the global commons and that no nation can lawfully restrict navigation rights.
The Philippines Pushes Back Against Chinese Incursions
The Philippines has become increasingly vocal in defending its maritime rights in the face of Chinese encroachments. On January 21, 2025, the National Task Force for the West Philippine Sea lodged an official protest against the presence of Chinese vessels near Ayungin Shoal (Second Thomas Shoal), a strategic reef within Manila’s Exclusive Economic Zone (EEZ). According to Philippine officials, Chinese coast guard and maritime militia vessels have been conducting “illegal operations” in the area, disrupting fishing activities and asserting control over the disputed waters.
President Ferdinand Marcos Jr. has reaffirmed his country’s commitment to the 2016 international tribunal ruling that rejected China’s sweeping maritime claims. Despite China’s disregard for the ruling, the Philippines continues to strengthen security ties with the United States and other regional allies.
China’s Potential FONOPs in the Northern Pacific
In a significant development, reports indicate that China may conduct its own freedom of navigation operations in the northern Pacific in response to U.S. activities in the South China Sea. According to a report from TASS News, Beijing is considering sending PLA Navy ships near U.S. territories such as Alaska or the Hawaiian Islands, mirroring the operational pattern set by the United States.
A move of this nature would mark a shift in China’s naval strategy, extending its presence beyond the first island chain and asserting its right to operate in international waters off the U.S. coastline. Analysts suggest that such operations could be part of Beijing’s broader strategy to challenge American military dominance and send a clear message that it, too, can project power far from its shores.
Implications for Regional and Global Stability
The strategic contest in the South China Sea is not just about territorial control; it has significant implications for global trade and security. Over $3.4 trillion worth of goods transit through these waters annually, making them a critical artery for the global economy. Any escalation in tensions could disrupt supply chains and heighten military risks in the Indo-Pacific region.
Additionally, a potential Chinese FONOP near U.S. waters would exacerbate tensions between the two nations, raising the specter of a new phase in their strategic rivalry. Such an operation could provoke countermeasures from the U.S. Pacific Fleet, further entrenching the cycle of military posturing.

The Next Move
The U.S. Navy’s recent freedom of navigation operations in the South China Sea have once again highlighted the fraught maritime contest between the world’s two largest powers. As China considers extending its operational reach with similar maneuvers in the northern Pacific, the situation underscores a fundamental geopolitical standoff with global ramifications. While the U.S. seeks to enforce international law through its FONOPs, China’s potential response in American waters could redefine the strategic landscape.
Whether these maneuvers lead to a diplomatic breakthrough or further militarization of the world’s most contested waters remains to be seen. What is clear, however, is that the South China Sea will remain a flashpoint for the foreseeable future, with both Washington and Beijing unwilling to cede ground in their pursuit of strategic dominance.
