The Hang Seng index fell 0.7 percent, to 21,161.50, while the China Enterprises Index lost 1.3 percent, to 9,090.85 points.
Energy shares led main indexes lower, as oil prices fell sharply in response to disappointing results from the weekend meeting.
Some 18 oil exporting nations gathered in Doha, Qatar, in an attempt to agree on stabilising output at January levels until October 2016. The deal fell apart after Saudi Arabia demanded that Iran join in. (Reporting by Samuel Shen and Nathaniel Taplin; Editing by Richard Borsuk)
