Philippine President Expresses Concern Over Russian Submarine in Exclusive Economic Zone

President Ferdinand Marcos Jr. described the recent presence of a Russian attack submarine within the Philippines' exclusive economic zone (EEZ) in the South China Sea as "very worrisome." Speaking to reporters on Monday, he emphasized the significance of safeguarding the country's territorial waters, stating:

"Any intrusion into the West Philippine Sea, of our EEZ, of our baselines, is very concerning."

Incident Details

The Russian Kilo-class submarine, identified as UFA 490, was detected 80 nautical miles off the coast of Occidental Mindoro on November 28, according to Philippine Navy spokesperson Roy Vincent Trinidad. The Philippine Navy frigate BRP Jose Rizal established radio contact with the submarine, which confirmed its identity and stated it was awaiting improved weather conditions before continuing its journey to Vladivostok, Russia.

Naval forces escorted the submarine to ensure adherence to maritime regulations, although no further explanation was provided for its presence in Philippine waters.

Submarine Capabilities and Context

Kilo-class submarines, first introduced in the 1980s, are renowned for their stealth capabilities and have undergone continuous upgrades, making them some of the quietest submarines in operation.

The incident has heightened concerns over increased Russian and Chinese activity in the region. Russia and China, allies under a declared "no limits" partnership, conducted joint live-fire naval exercises in the South China Sea earlier this year.

Geopolitical Implications

The South China Sea remains a flashpoint for territorial disputes. The Philippines, a U.S. treaty ally, has faced growing tensions with China due to overlapping territorial claims. A 2016 international arbitration ruling invalidated China's expansive claims, but Beijing has refused to recognize the decision.

This latest development adds another layer of complexity to the region's security dynamics, with Manila urging vigilance in upholding its sovereignty. The Russian Embassy in Manila has not yet commented on the incident.

As regional tensions persist, President Marcos’ remarks underline the Philippines' commitment to safeguarding its maritime interests amid increasing foreign activity in its waters.
