Reading this excellent piece by Chris Buckley on Xi’s search for “absolute loyalty,” it’s hard not to think the PLA’s new ideological rectification campaign could actually aggravate the very problem of “divided hearts” Xi believes plagues the military. nytimes.com/2026/05/09/world…

China is stepping up antifascist rhetoric, military pressure, and legal instruments to lay the groundwork to legitimize future “targeted actions", whether military in nature or akin to law enforcement operations.

This is likely to continue intensifying in 2026/2027, and Beijing is unlikely to reconsider its strategy unless there is an electoral demonstration in Taiwan that the use of antifascism and targeted extraterritorial actions is counterproductive.

Une analyse du rôle croissant de la rhétorique "antifasciste" dans la politique taiwanaise de la Chine - la construction d'un récit pour convaincre de la légitimité, voire de la légalité, du recours à des formes de violence. @i_montaigne institutmontaigne.org/expres…

China's angry statement at Trump's Venezuela strike can't all be about international law. What else might it be unhappy about? Maybe Beijing doesn't like that: 1: Trump now 'runs' Venezuela's oil, at a time when China needs an alternative to Iranian oil 2: Chinese radars didn't work against incoming US missiles 3: A Chinese delegation had just met Maduro. "Whatever assurances Beijing gave in that meeting had a remarkably short lifespan," @michaelsobolik says My take: Trump's Venezuela strike will likely change China's regional calculations asia.nikkei.com/spotlight/tr…
