Putin's Meeting with Philippine President Signals Bigger, Trickier Russian Role in Disputed South China Sea Ralph Jennings TAIPEI, TAIWAN - Philippine President Rodrigo Duterte's meeting this week with Vladimir Putin in Russia signals Moscow's interest in playing a tricky but persuasive role in the South China Sea maritime sovereignty dispute now dominated by China and the United States, specialists in the region say. Duterte is visiting Russia October 1-5, partly to speak with Putin about increasing security and defense cooperation, the Philippine presidential office website says. Duterte toured Vnukovo Military Base Airport in Moscow on Wednesday. Russia might offer to sell arms to the Philippines, experts say, having sold weapons to other Southeast Asian countries claiming the 3.5 million-square-kilometer sea. Russian arms sales to the Philippines would reduce U.S. military influence in the sea but yet be handled in ways that avoid weakening the presence of Moscow's decades-old friend, Beijing, they add. "For Russia, I think it's clear U.S. influence is very extensive in the Philippines, so by selling arms to the Philippines they are in effect promoting their political influence," said Aaron Rabena, a research fellow at Asia-Pacific Pathways to Progress Foundation, a Manila research organization. "There might be certain concern by China about what type of weapons we will get from the Russians and where those weapons will be used," Rabena added. Were they to be used in the South China Sea, he said, "then the Chinese might raise their eyebrows." .
