Obama says a deal signed on Monday to give the US military greater access to Philippine bases will help strengthen security in the region. He said it also will allow for a faster response to natural disasters.
It is being seen as an effort by Washington to counter Chinese aggression in the region. Obama says he hopes at some point that the US will be able to work cooperatively with China as well.
Obama was speaking at a news conference with President Benigno Aquino III.
