The Hong Kong Jockey Club has cancelled the midweek race meeting at Happy Valley due to ongoing protests and political unrest.

It is the second time in the past two months a Hong Kong race card has been called off because of the social turmoil gripping the country.

The Jockey Club said its decision to cancel Wednesday's Happy Valley meeting was made in the interests of its employees and racegoers.

"In organising race meetings, the Club always puts safety as a top priority," the HKJC said in a statement.

"The Club has been monitoring the situation in Hong Kong closely.

"It has conducted a thorough risk assessment of the race meeting tonight and concluded that the latest social unrest and public transportation situation throughout the territory do not support our employees and racegoers arriving and particularly departing from the racecourse smoothly and safely."

The HKJC is due to host it's major International meeting at Sha Tin on December 8.

Happy Valley is situated on Hong Kong Island close to the unrest while Sha Tin is in the New Territories.

Sha Tin hosts the annual International meeting in December featuring four Group One races.
