U.S. President Barack Obama put tensions over Beijing's claims to the South China Sea squarely on the agenda ahead of an Asia-Pacific summit on Tuesday, pointedly visiting the main warship of close ally the Philippines shortly after he landed in Manila.
While Obama affirmed a commitment to the Philippines' security and to freedom of navigation in regional waters, a senior official in Beijing said China was the real victim of the waterway dispute because other countries had illegally occupied islands there.
Xi also arrived in Manila on Tuesday, but did not make any public comments.
Shortly after Air Force One touched down in Manila, Obama boarded the Gregorio del Pilar, a Philippines navy frigate that was a U.S. Coast Guard cutter until 2011 but on Tuesday flew the flags of the two allies.
