PLAN already defeated USN in the South China Sea. Why else did the USN scurry away like rats in July 2017 when they initially threatened to enforce the PCA ruling? Your boasting is delusional. Just like India boasting about its military while unilaterally retreating in Doklam after a spanking.
LOL so-called US intelligence thought China could not spank USA in Korea, in the East China Sea and in the South China Sea. (They did, however, correctly predict India's miserable defeat.) Yet, we defeated USA and all its allies to get to our present position as the undisputed hegemon of East Asia.
LOL boasting about "sub-Mekong delta shupa powa" is brain gymnastics for somebody with obvious Agent Orange effects
LOL this is the PDF section for China but all the Viets are here crying about how we butchered your three frogmen marines with our automated explosives
