China has warned countries in Asia to be vigilant about the US "using" them, after American forces secured access to a further four military bases in the Philippines.
The United States already had access to five military bases in the Philippines, and would be given access to four more locations under the 2014 Enhanced Defense Cooperation Agreement (EDCA), US Defense Secretary Lloyd Austin and Philippines Defence Secretary Carlito Galvez said during a joint news conference at the Philippines' military headquarters in Manila.
