Sin Chung-kai

Individual CALD member Chung-Kai Sin was formerly the Deputy Chairman of the Democratic Party of Hong Kong, which was dissolved at the end of 2024 because of irresistible political pressure. He had been a member of its Central Committee since the party’s founding in 1994. 

Born and educated in Hong Kong, Sin was part of what used to be the city’s vibrant political institutions. His long public service record includes his being a member of the Housing Authority from 2001 to 2009. He also served as an elected representative at all three tiers of the Hong Kong government, starting at the Kwai Tsing District Council from 1985 to 2003, and then at the Regional Council, which was abolished by the Hong Kong Special Administrative Region (HKSAR) government in 1999. 

At the Legislative Council or Legco, Sin represented New Territories South from 1995 to 1997, and then the Information Technology Sector from 1998 to 2009. He was also an elected Legislative Councilor of Hong Kong from October 2012 to September 2016. In addition, Sin was among the 1,200 members of the Election Committee that selected nominees for the post of HKSAR Chief Executive.

In November 2019, Sin was again elected Kwai Tsing District Councilor for a term that would have run from 2020 to 2023. But he was disqualified from the post because of a criminal conviction for organizing an unauthorized assembly. The conviction came with a jail sentence of 14 months.  The “unauthorized assembly” was part of the anti-extradition movement in Hong Kong that began in 2019 and lasted until 2021.

Sin is a lifetime member and fellow of the Hong Kong Computer Society. He has a Bachelor of Science degree from the University of Hong Kong, as well as a Master of Business Administration degree from the Chinese University of Hong Kong. He is married and has two sons.
