Coinciding with the 4th plenum of the 12th NPC session, the USS John S. Stennis, a Nimitz-class aircraft carrier; two guided-missile destroyers, the USS Chung-Hoon and USS Stockdale; the guided-missile cruiser USS Mobile Bay; and the supply ship USNS Rainier have been operating in the eastern part of the South China Sea since March 1, 2016. The command ship 'Blue Ridge', the floating headquarters of the Japan-based 7th Fleet, is also in the area, en route to a port visit in the Philippines. Fu Ying, a spokeswoman for China's National People's Congress (NPC) said “The accusation can lead to a miscalculation of the situation. If you take a look at the matter closely, it’s the US sending the most advanced aircraft and military vessels to the South China Sea.”
