Russian navy vessels arrived in the Philippines on Thursday for joint exercises as part of a drive for new security ties under President Rodrigo Duterte's revamped foreign policy of courting the traditional foes of Manila's top ally, Washington.

The guided-missile cruiser Varyag, accompanied by the fuel tanker ship, Pechenge, are on a four-day goodwill visit to the Philippines, the second port call by Russian warships in three months.

The move is part of what Duterte describes as a pursuit of a constitutionally mandated "independent foreign policy". He has made no secret of his grudge against the United States and has made befriending Russia and China the priority of his diversification drive.

Captain Lued Lincuna, director of the Philippine navy's public affairs, said the Philippines hoped to learn from the Russians during training activities and a demonstration of advanced equipment and weapons systems.

The schedule includes training and sports activities with the flagship vessel of the Russian Pacific fleet, plus a Russian concert in a park.

Russian commander Captain Alexsei Ulyanenko said the port call would make a "significant contribution" to strengthening relations and maintaining stability in the region.

Moscow wants to help Manila combat extremism and piracy, stepping up cooperation and training in areas where the Philippines has traditionally worked closely with its former colonial master the United States.

The relationship is expected to develop further next month when Duterte and Russian counterpart Vladimir Putin witness the signing of defense agreements in Moscow.

When Duterte met Putin for the first time last year, the Philippine leader spoke at length about what he called U.S. "hypocrisy".

Duterte has instructed his defense minister to look into how the Philippines could acquire modern military equipment from Russia, like drones, night-vision gear, sniper rifles, and even helicopters. (Reporting by Manuel Mogato; Editing by Martin Petty and Michaedl Perry)
