Koo was the founding chairman of the
Straits Exchange Foundation (SEF). On 16 December 1991, a little over ten months after the establishment of the SEF, the authorities of
People's Republic of China (PRC) set up the
Association for Relations Across the Taiwan Straits (ARATS), with
Wang Daohan as its chairman. The following year Koo and Wang held preliminary talks in
Hong Kong that resulted in the so-called "
1992 Consensus" and facilitated negotiations of practical matters. However, the content and the existence of this "1992 consensus" is widely disputed. In 2001, Koo publicly affirmed that the meeting did not result in a consensus on the issue of "one-China". In April 1993, Koo and Wang met in Singapore to hold the first formal discussions between Taipei and Beijing since 1949. The two met again in Shanghai in 1998. On 18 October 1998, Koo met
Jiang Zemin,
General Secretary of the Chinese Communist Party, in Beijing, in what was then the highest-level talks yet held between the two sides. The talks were called off by Beijing in 1999 after ROC President
Lee Teng-hui proposed his
two-states theory. ==Death==
