THOUSANDS of US and Filipino military personnel began annual combat drills today that have antagonised China, including a “full-scale battle scenario” to simulate the defence of the Philippine archipelago and seas.

The annual Balikatan military exercises are due to continue until May 9, involving about 9,000 US and 5,000 Filipino soldiers, sailors and air force personnel. Fighter jets, warships and an array of weaponry including a US marine anti-ship missile system will be involved, US and Philippine military officials said.

China has resolutely opposed such war drills in or near the disputed South China Sea and in northern provinces of the Philippines close to Taiwan, especially if they involve US and allied forces that Beijing says aim to contain it and, consequently, threaten regional stability and peace.
