The USSR coming closer to nuking China than arguably any other country has since WW2 didnt help
Also
why post colonial bourgeois nationalism flared up in border struggles with Vietnam and China, and now regrettably we have a china that continues many of these trends.
China has diplomaticaly resolved the large majority of the border and maritime disputes it found itself in with the establishment of the PRC due to the massive changes from decolonial movements in the region, constantly changing and uncertain borders for China in the previous period, lack of border treaties with its neighbors before 1949. Often by surrendering the majority of the disputed ereas to the neighbouring country. Since its inception the PRC resolved border disputes with Vietnam, Myanmar, Nepal, Kazakhstan, Kyrgyzstan, Laos, Mongolia, North Korea, Pakistan, Tajikistan, and Russia without maximalist demands, without domination through coercion and without lasting negative impact on their relations (from that aspect at least).
As for the rest of the comment this seems like half baked Pekingology to me. Psychoanalysing Xi's tone and word choice. Finding some lib professors and analysts from Shanghai saying their own shit and doing the "they werent cencored by the ever cencoring no freeze peach 1984 CCP so that indicates a change in attitude state wide". Like, there are probably hundreds of thousands of west loving libs both in the CPC and in chinese univercities and commentators, there are thousands of talks, forums and articles every week across China and China always had reasonable tolerance for these people saying their minds no matter the actual shifts and trends in domestic and foreign policy. We all know these things. Gathering 5, 10 or even 50 quotes from them to make any point isnt too hard. Im 100% sure they could have written the same article last year, and the year before. Hell im sure someone else did.
Weird for someone as knowledgable as you to continue posting low quality stuff like this along with "ohhhh its so over" commentary. On your 4th account in 5 months no less
