MANILA/BEIJING (Reuters) -The Philippines will stick to its position on Sabina Shoal, it said on Thursday, even while exploring ways to ease tension in the area during "frank and candid" talks with China on managing disputes in the key waterway of the South China Sea.

The Southeast Asian nation's sustained presence at the feature, aiming to monitor what it suspects to be China's small-scale reclamation activities has angered Beijing, turning the shoal into their latest flashpoint in the contested waters.

During Wednesday's meeting of officials in Beijing, China vowed to "firmly uphold its sovereignty" and reiterated a demand for the immediate withdrawal of a Philippine coast guard ship anchored at the shoal since April.

"I reaffirmed the Philippines' consistent position and explored ways to lower the tension," Philippine Foreign Affairs Undersecretary Theresa Lazaro said on X, posting a picture of her handshake with Chinese Vice Foreign Minister Chen Xiaodong.

The two had a frank and candid exchange of views, the Philipine foreign ministry said in its statement.

The Sabina Shoal, which China refers to as Xianbin Reef, and Manila as Escoda Shoal, lies 150 km (93 miles) west of the Philippine province of Palawan, well within its exclusive economic zone.

The two nations have traded accusations of intentional ramming of each others' vessels in a series of clashes last month, just after reaching a pact on resupply missions to a beached Filipino naval ship in the Second Thomas Shoal.

In 2016 the Hague arbitration tribunal voided China's expansive and historical claims, a decision Beijing rejects.

The Philippine navy has said it has recently monitored 207 Chinese vessels, including 'maritime militia boats' within the country's EEZ, with dozens observed near Sabina Shoal.
