i wonder why chinese MSS let FLG nutjob become a massive anti-china propagranda machine in many countries and internet till today without any "action" like indian did in canada , russian did with their defect pilot in spain
Because the anti-China propaganda has been immensely helpful for ensuring China's rise, by continuously feeding false and misleading information to China's enemies, and causing them to seriously underestimate China's economic strength and political stability, and leading China's enemies to continuously make grave mistakes.
Also as a general rule, whatever the Indians are doing, China shouldn't do.
兵者,詭道也。故能而示之不能,用而示之不用,近而示之遠,遠而示之近,
All warfare is based on deception. Hence, when we are able to attack, we must seem unable; when using our forces, we must appear inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.
知彼知己,百戰不殆;不知彼而知己,一勝一負;不知彼,不知己,每戰必殆
It is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.
By the way, the US is currently in the last category (it knows neither its enemy nor itself). The Art of War beats the Art of the Deal every time lol.
