A delegation led by Cheng Li-wun, chairwoman of the Chinese Kuomintang party, wrapped up its six-day visit to the Chinese mainland on Sunday. They visited Jiangsu, Shanghai and Beijing and were met with by Xi Jinping, general secretary of the Communist Party of China Central Committee. The visit is widely seen as a fresh opportunity to reopen channels for peace across the Taiwan Strait, despite existing tensions and challenges. CGTN's Zheng Yibing followed the delegation throughout their visit and filed this report on the significance of the visit at this point in time.
