the president of Taiwan is extremely important for the peace and harmony between China and USA. notice during Ma President era, there is not much tension between US and China as well
On the contrary, the cssta was signed in 2013, and the early signs of USA-china trade war started in 2016
this of cos has nothing to do with Taiwan presidency but the message that is sent to china from Taiwan and other countries, has to do with the direction that china adopt thereafter.
which means if china believe that they can make unfair trades even more unfair then USA is more likely to react strongly.
Ma’s failed policies didn’t just cause the downfall of kmt in his own country. It does give the wrong message to china, and though not the deciding factor is a contributing factor to increased USA-china tension
in the same line, Sri Lanka and all the oboe debt trap countries also lead to that
