ANGKOK (AP) — With its ground troops forced to pull back in Ukraine and regroup, and its Black Sea flagship sunk, Russia's military failings are mounting. No country is paying closer attention than China to how a smaller and outgunned force has badly bloodied what was thought to be one of the world's most powerful armies. 

China, like Russia, has been ambitiously reforming its Soviet-style military and experts say leader Xi Jinping will be carefully parsing the weaknesses exposed by the invasion of Ukraine as they might apply to his own People’s Liberation Army and his designs on the self-governed island of Taiwan. 

“The big question Xi and the PLA leadership must be asking in light of Russian operations in Ukraine is whether a military that has undergone extensive reform and modernization will be able to execute operations that are far more complex than those Russia has undertaken during its invasion of Ukraine,” said M. Taylor Fravel, director of the security studies program at the Massachusetts Institute of Technology.

Russia's armed forces have undergone an extensive process of reform and investment for more than a decade, with lessons learned in combat in Georgia, Chechnya, Syria and its annexation of Crimea helping guide the process. The Ukrainian invasion, however, has exposed weaknesses from the top down.
