Agreement and documents for Kazakhstani to Hong Kong.

Good day. As I know there was an Agreement signed on 9 May 2012 between Kazakhstan and Hong Kong Special Administration stating that for Kazakhstan citizens no need to have visa to enter Hong Kong. Could you please tell me whether this Agreement is in force. And if it is I am planning to travel to Hong Kong after a week, would I need any extra documents? I will be flying there from Kuala Lumpur, will I be able to get it in any airport or in some only?
Thank you very much.
