[7] The pro-Beijing Federation of Trade Unions (FTU) selects members for two Legislative Council seats comprising the Labour functional constituency.

He made a post on his Facebook page boasting that a footbridge in his district (Provident constituency), on Tong Shui Road, had been cleared of homeless people (and their belongings) on 23 November 2017.

An anti-poverty activist said that Kwok's post was reminiscent of the concurrent purge of Beijing's so-called "low-end population" that has drawn international attention.

[12] In response to the controversy, Kwok responded that the street sleepers posed a health and safety issue, and that he had received complaints about the footbridge from his constituents.

Live footage filmed during the meeting by Radio Television Hong Kong showed Kwok grabbing Raymond Chan Chi-chuen by the collar and dragging him to the floor.

Chan said he would also launch a crowdfunding campaign to fund private prosecution against Kwok, as he stated that he had little faith in the police nor the Department of Justice.

[18] On 22 November 2018, Kwok voted against a legislative motion that called for the government to explore legal unions for same-sex couples in Hong Kong.

[22][23] LGBT singer Anthony Wong Yiu-ming stated that Kwok's stance represented outdated views on homosexuality from the pro-Beijing faction.

[22] On 14 January 2021, Kwok participated in a video conference of the Legislative Council's Panel on Housing, where he was suspected to have been driving while in the meeting, potentially violating the Road Traffic Ordinance.

[25][26] During the debate on the Motion of Thanks for Chief Executive's 2020 Policy Address on 21 January 2021, Kwok falsely claimed The Guardian (衛報) is a paper for WHO (世衛).
