Tiong King Sing

Dato' Seri Tiong King Sing (simplified Chinese: 张庆信; traditional Chinese: 張慶信; pinyin: Zhāng Qìng Xìn; born 3 September 1961) is a Malaysian politician. He is currently the Member of the Parliament of Malaysia for the Bintulu constituency in Sarawak and East Asian special ambassador. He is the President of the Sarawak Progressive Democratic Party (SPDP), a component party of Malaysia's governing Barisan Nasional coalition.

Tiong was originally a member of the Sarawak National Party but was dismissed in 2002 for what the party cited as disciplinary reasons. He subsequently joined the SPDP. In 2007 he became involved in a dispute with police administration alleging that criminal gangs were acting with impunity throughout Sarawak but that his concerns were not being addressed by police. His outspokenness was reported to have triggered a large police operation against criminal organisations in the State. Tiong subsequently received mail threats, including a parcel of shotgun cartridges, at his constituency office. At the 2008 election, he successfully defended his seat receiving 73% of the vote.
