The social media site Rappler reports that “Pentagon chief Chuck Hagel will discuss expanding the US military’s presence in the Philippines in a visit to the country Friday as Manila looks to defend its territorial claims in disputed waters.”

“Hagel flew into Manila on Thursday amid fresh strains between the Philippines and China over disputes in the South China Sea, with President Benigno Aquino calling off a visit to Beijing next week at China’s request.”

“The Philippines has accused Beijing of an arms buildup and coercive moves in the strategic South China Sea, which is believed to hold unexploited oil and gas deposits.”
