Lien arrived in Beijing on Sunday and is scheduled to leave for Taiwan on Wednesday. The 30-strong delegation has representatives from the political, religious and business sectors as well from the media.
Taiwan leader Ma Ying-jeou met with Lien on Friday, and asked Lien to extend his greetings to Xi, the Hong Kong-based takungpao.com reported.
Lien sent Taiwan-produced organic food, including oatmeal, dried fruit, and barley noodles, as a gift to Xi, Taiwan-based TVBS reported.
Wang Hailiang, a researcher with the Taiwan Studies Center at the Shanghai Academy of Social Sciences, said the meeting went well.
"General Secretary Xi Jinping recalled his private friendship with Lien during the meeting, showing his willingness to improve cross-Straits ties," he said.
Cross-Straits communication will be steadily promoted by both parties, he said.
Chen Xiancai, a professor with the Taiwan Research Institute at Xiamen University, said that economic exchanges will continue to play a leading role in cross-Straits relations.
"Political dialogue between the highest leaders of both parties is in the distant future," Chen said. "NGOs, such as think tanks, should take the first step."
