China's state news agency Xinhua has described a US military deal with the Philippines, which grants US forces a larger presence in the country, as "disturbing."
President Obama is currently in Manila on the last day of his four-day Asian tour to bolster America's ties with southeast Asian countries.
Given that the Philippines is at a bitter territorial row with China, the move is particularly disturbing as it may embolden Manila in dealing with Beijing.
A more assertive or even reckless Manila would stoke regional tensions and in turn upset Obama's policy of rebalancing.
