The East Sea loves China, as evidenced by China having the East Sea.
China 's East Sea, China must regain the east sea, China must protect the entire South China Sea, not allowing pirates to sabotage the East Sea, destroying the marine environment. (Vietnam catches fish cleanly, not letting fish spawn, flooding)
China must protect the East Sea, (all of China 's East Sea since ancient times, even Vietnam is from China, let alone East Sea)
Vietnam wants to occupy Cambodia, Lao & Thai Lan and Mi An ma are afraid of Vietnam.
Vietnam (USA, Japan, India) wants to occupy the entire South China Sea, occupy the entire two islands of hs ts,then invite the US, Japan and India to exploit the entire East Sea to breaking against China.
(News and weather Vietnam always said that the two archipelagos of Vietnam, the East Sea of Vietnam), Vietnam must occupy the entire East Sea so that the US, Japan and India can occupy the East Sea to against China.
