BY A STAFF REPORTER: The United States and the Philippines announced on Thursday an agreement to expand American military presence in the Southeast Asian country, where U.S. forces would be granted access to four more Philippine military camps, effectively giving them new ground to ramp up deterrence against China’s increasingly aggressive actions toward Taiwan and in the disputed South China Sea.The agreement between the longtime treaty allies under a 2014 defense pact was made public during the visit of U.S. Secretary of Defense Lloyd Austin.
