And they conveniently gloss over British imperialism (which was extensive and explicitly said as imperialism), French imperialism, and German ones. (Germany before WWI was no saint towards China eitehr, but you won't find the William II-do-to-Chinese-as-historical-Huns speech during the Boxer Rebellion appearing in modern mainland Chinese texts). But many will rise up and denounce the then US SoS John Hay about his "Open Door" policy and Teddy Roosevelt as preparing a subtle strategy to keep China prized for imperialistic expansions from the United States later.
Selective memory, and the first lesson of Soviet/Communist/"liberal"/"progressive" histography is when you learn how P.R. China teaches Chinese history.
