I'd say a reason, not necessarily the reason. Taiwan rubbed China's face in it for decades, it seems like a long-held grudge: > During the 1960s and 1970s, the National Palace Museum was used by the Kuomintang to support its claim that the Republic of China was the sole legitimate government of all China, in that it was the sole preserver of traditional Chinese culture amid social change and the Cultural Revolution in mainland China, and tended to emphasize Chinese nationalism. Even though, if you read further down in the article, there's not as much acrimony about it in recent years. Still, China has had dreams to invade Taiwan for decades, mostly for nationalist reasons, and this is likely one of the reasons that's higher in the list.
