Lien, an honorary chairman of Taiwan's ruling Kuomintang (KMT) party, will discuss issues of mutual interest with Xi during a three-day visit to Beijing beginning Monday under the invitation of the Chinese side, Lien's office said in a statement.
"Members of the delegation include people from various civilian sectors who will voice their expectations and suggestions on future cross-strait exchanges... In the hope that China can directly understand and keep abreast of Taiwan's public opinions," it said.
Wang Yu-chi, Taiwan's top official overseeing China policy, on Tuesday met his Chinese counterpart Zhang Zhijun in Nanjing in a symbolic yet historic move between the former bitter rivals.
Beijing still claims the self-ruled island as part of its territory awaiting reunification.
Lien became the first leader of the nationalist KMT party to visit China in 56 years when he met President Hu Jintao in 2005 to formally end hostilities with the communists. Last year, Lien met Xi in Beijing.
