In April and May 2005, Lien Chan and James Soong made separate trips to Mainland China, during which both explicitly supported the Consensus of 1992 and the concept of one China and in which both explicitly stated their parties' opposition to Taiwan independence. Although President Chen at one point supported the trips of Lien and Soong for defusing cross-strait tensions, he also attacked them for working with the "enemy" PRC. On April 28, 2008, Honorary Chairman Lien Chan of the then opposition Kuomintang visited Beijing and met with Hu Jintao for the fourth time since their historic encounter on April 29, 2005 in their respective capacity as party leaders of both the Chinese Communist Party and the KMT. Lien also met Chen Yunlin, director of the PRC's Taiwan Affairs Office of the State Council.
