From countering a Western "information war" during a Taiwan conflict to using "shock and awe" to swiftly subdue the island's forces, Chinese strategists are soaking up lessons from Russia's Ukrainian quagmire, diplomats, scholars and analysts say.

Chinese military experts are discussing the conflict in private chat groups, offering their takes on Western involvement in Ukraine and Russia's perceived failings, say two scholars and four Asian and Western diplomats who are in touch with Chinese strategists.

Although their conclusions have yet to surface in official military journals or state media, Russia's failure to quickly crush the Ukrainian military is a key topic — as are fears about how well China's untested forces would perform.
