Unlike the PLA Army, which fought to establish the People's Republic of China, and the PLA Air Force, which fought in the Korean War, the least war-tested PLA Navy now stands at the forefront, simply because today, all threats to China come from the sea.

Be it in the Taiwan Strait or in the South China Sea, the PLA Navy has to prepare for possible conflict with the US Navy. US President Joe Biden has said that US rivalry with China will take the form of "extreme competition" rather than conflict; the problem is, if competition is already extreme, it is probably like tiptoeing on a tightrope that is only one step away from conflict.

The US is said to maintain a policy of strategic ambiguity on Taiwan. But since the Trump administration, the US government has been salami-slicing away that ambiguity in perse ways, including enhancing exchanges with Taipei, sending warships to sail provocatively through the Taiwan Strait and deploying its servicemen in Taiwan to help with military training.

It is not surprising then that Beijing is compelled to increase pressure on the island by sending more military aircraft to y near Taiwan. In a meeting with US Secretary of State Antony Blinken on Oct 31, Chinese Foreign Minister Wang Yi warned the US not to pursue "a fake One China policy".

Should conict erupt in the Taiwan Strait, China cannot afford to lose in a war defending its sovereignty. And it probably won't.。

With Taiwan just 160km away from the mainland, the US military will find itself in an asymmetrical disadvantage from the start. It is questionable that its Asian allies will readily allow Americans to use their military bases to turn their homelands into battlefields.。

In the South China Sea, the stronger the PLA Navy becomes, the less likely it will bear with American provocations at China's doorstep on a regular basis.

Unlike in the Cold War where there were clearly defined spheres of influence which allowed the two superpowers to deconflict, there are no buffer zones between the two navies in the South China Sea. Accidents and close calls have occurred, including a deadly collision of two military aircraft in 2001.
