Vietnam has been chosen to host the playoff round of the Asian Football Confederation (AFC) Asian Qualifiers for the 2012 London Games from March 25 to 31.
Previously, Malaysia had been chosen but facilities there did not meet the requirements, so AFC decided to move the venue to Hanoi.
Currently, only the first leg matches of the third qualifying round have been played and it is not clear which teams will go to Vietnam for their playoff matches.
Japan, South Korea and Uzbekistan are leading the three groups, followed by Oman, Iraq and Syria. The second-placed teams will play their playoff matches in Vietnam.
However, Qatar and Australia still have a chance to finish in second places to travel to Vietnam for the playoff round.
In the second qualifying round, Vietnam lost 6-1 to Saudi Arabia, who has no chance to go any farther than round 3.
As a rule, the three top teams from Asia automatically qualify for the London Olympics with the fourth place team competing against the fourth best team from Africa, which is Senegal this year.
The second-placed teams in the three groups in Asia will play round robin style playoff matches in Vietnam and the best team will play Senegal in the English city of Coventry on April 12.
