MANILA, Philippines — China deployed on Saturday six more maritime militia ships from Panganiban (Mischief) Reef to Ayungin (Second Thomas) Shoal as it enforces its new regulation to detain foreigners it suspects of trespassing its borders, including disputed areas in the South China Sea.

According to retired United States Air Force Col. Ray Powell, director of SeaLight, a maritime transparency project that monitors and reports activities in the South China Sea, one Chinese ship pushed further east of the atoll early Saturday morning.
