Thailand will kick off with a home game against Palestine, while fellow Southeast Asian sides Malaysia and Indonesia will host Pakistan and Turkmenistan respectively in February.
Singapore will visit Yemen before hosting the decisive second leg two weeks later, while Hong Kong will face the Maldives.
Kuwait, whose senior side recently won the WAFF Championship, will first host Bangladesh, while UAE will take on Sri Lanka, Oman welcome Tajikistan and Jordan play Chinese Taipei.
India, whose senior side are competing in the AFC Asian Cup for the first time in January, will take on Myanmar.
The 11 winners will join the top 13 highest-ranked sides in round two, which will also be played over two legs on June 19 and 23, 2011.
Korea Republic are the top seeds and are followed by Australia, China, Japan, Iraq, Bahrain, Qatar, Saudi Arabia, DPR Korea, Syria, Lebanon, Uzbekistan and Vietnam.
The winners from the 12 ties will be drawn into three groups of four for round three, with teams playing each other home and away across six matchdays from September 21, 2011 through to March 14, 2012. The top team in each group will automatically earn a place at the Olympics.
