HONG KONG, Aug 8 (Reuters) - Beijing's top representative office in Hong Kong said on Saturday it strongly condemns sanctions imposed by Washington that targeted the bureau's most senior official in the city, in addition to other senior current and former officials.

The head of Beijing's Liaison Office, Luo Huining, was among those Washington accused of curtailing political freedoms in the global financial hub, along with Hong Kong leader Carrie Lam.

"The unscrupulous intentions of the U.S. politicians to support the anti-China chaos in Hong Kong have been revealed, and their clowning actions are really ridiculous," the Liaison Office said in a statement.
