Unfortunately, sometimes it's also contributing to each side knowing each other better. There was some disenchantment from many Taiwanese businessmen in China, who did not always have positive experiences. It's not necessarily the case that trade between the two sides has improved relations between them. Of course, the intent was there.
From the Chinese side, it was also seen as an inducement to convince the Taiwanese to move closer to China. Also, many Taiwanese businesses saw there was a risk of deterioration of their economic position if they became integrated too closely with China. One instigation of the Sunflower Movement was precisely because the previous president Ma Ying-jeou wanted to move Taiwan closer to China. The young entrepreneurs in Taiwan were really worried about that.
