Wife of Hong Kong's Chief Executive is in no conflict of interest by setting up a food waste recycling company, because it's a non-profit organization, Secretary for Constitutional and Mainland Affairs Raymond Tam said on Wednesday.

His comment came in response to a media enquiry. Tam said the company, named "Food for Good", aims to contribute to environmental sustainability, through establishing a platform to promote food waste recycling and waste reduction at source in Hong Kong. The project also proposes to donate food it receives to the needy.

He said "Food for Good" was incorporated in November, but has yet to commence operation. The CE's wife, Regina Leung Tong Ching-yee, is one of the founding members of the project. After the project is formally inaugurated, she intends to resign from the directorship and take up an honorary post. She will obtain no economic benefit.
