As Chiang-kai Shiek would respond: "come get it 😡🚀"

On a more serious note, I wouldn't say it was robbed, it was basically the only capital that was allowed to leave during wartime because by all measures the bulk of industry and human capital remained seized in China. (Communism is predicated on theft) The gold that left mainland China certainly doesn't belong to the CCP -- there's a pile of artillery shells on Kinmen to make that point. The narrative that KMT bankrupted mainland China is just another entry to the long list of excuses of how communists mismanaged resources; for the purpose to draw blame away from the central planners. For example, Chinese visitors to the National Palace Museum often say that the treasures were stolen but all it takes to shut them up is to say "well, you'd have all of this stuff and more if you guys didn't burn down everything in the Cultural Revolution"🤷
