Algernon Yau Ying-wah JP (Chinese: 丘應樺; born 1959) is the current Secretary for Commerce and Economic Development in Hong Kong, appointed on 1 July 2022 as part of John Lee's administration.

[5] In December 2023, Yau appealed to the US government to stop a proposed bill that would strip HKETO offices in the US of special privileges.

[3] In September 2022, in response to Hong Kong and quarantine-free travel, Yau claimed that the government uses a pragmatic approach and will make a science-based decision.

Yau criticised the US ban hours after the WTO ruling, and stated of the US actions that it was "politically motivated and a vain attempt to interfere with Hong Kong's internal affairs through weaponizing trade.

He said that the move by the United States had "confused" customers and that his "government's successful challenge to a US ban on the 'Made in Hong Kong' label is a matter of upholding the SAR's separate status in the World Trade Organisation.
