Updated at 6.02pm: Taiwan's Nationalist Party Chairman Lien Chan and his delegation concluded their eight-day visit to the mainland on Tuesday and passed in transit through Hong Kong, a government spokesman confirmed. Mr Lien, who is chairman of the Kuomintang, and his party were returning to Taipei after flying out from Shanghai earlier on Tuesday. His wife, Lien Fang-yu also accompanied him. A pool of journalists, comprising staff members from APTN, Asia Television and the Hong Kong Economic Times covered the delegation's arrival at the Hong Kong International Airport. Further details were not available on Tuesday afternoon. Mr Lien's visit to the mainland was the first by a Nationalist leader since China and Taiwan split amid civil war in 1949. Taiwan barred contact with the mainland for decades but has eased those limits since the early 1990s. Since then, Taiwanese companies have invested about US$100 billion (HK$778 billion) in China. Mr Lien said that during his meeting with Chinese President Hu Jintao, he had stressed Taiwanese proposals for talks on a peace agreement and he said that the Chinese leader gave a 'positive response ' - although he didn't commit on any specific arrangements.
